Best Battery Powered 14″ Concrete Cutter (Cut-Off Saw) | Head-To-Head

A Concrete Cutter sometimes called a cut-off saw, masonry saw, road saw, “consaw,” or concrete saw is a hand-held tool designed to cut concrete, asphalt pavement, rebar, steel and plastic pipe. Typical uses include making openings in walls, floors, manhole structures, road surfaces, and curbs.

We all recognize that battery-powered saws require less maintenance, are easier to start, and forgo the need for the 50:1 fuel mixture.

Our industry is now experiencing an increased focus on the integration of battery-operated equipment across the job site, driving the discussion of gas tools vs. battery-powered tools. For us to even have this conversation we need to agree battery tools need to compete with gas in performance, power, and run-time.

We decided to perform a Head-to-Head test on four cordless concrete cutters (cut-off saws) to determine which one was the best saw and if these saws could compete with gas saws.

To give clarity to our testing we included the Husqvarna K770 gas saw, as a comparison standard.  Husqvarna has been making cut-off saws since 1958, and we chose the K 770 because it is a powerful, all-around concrete cutter with features that make it one of the best saws on the market.

Cordless Cut-Off Saw | Line-Up

Four manufacturers sent their cordless cut-off saws and saw blades.

NOTE – The Hilti cut-off saw is a 12″ saw but was allowed to participate in this test because it has a feature called OutCut, which allows it to cut at similar depths as the other three 14″ saws. To understand what OutCut is, the arm of the saw narrows to a smaller point compared to other saws and uses a smaller diameter flange-set for use with steel core diamond blades.

Our Testing Criteria

Our team scored the cordless cut-off saws on eight criteria, each ranked independently, and the “Overall Best Cordless Cut-Off Saw” was determined using the combined test results.

We include but did not rank Watt-Hours Per Cut, and Best Value categories, but list them here for your own informational purposes. We did NOT include decibel testing since all of these saws are well over the OSHA rating for hearing protection.

Scoring Criteria – Cordless Cut-Off Saws

1. Concrete Cutting Test – Most lineal feet cut in concrete with embedded rebar [Ave. speed]
2. Rebar Cutting Test – Fastest cutter of five ganged #4 rebar. [Ave. speed]
3. Watt-hour per cut – we include this for your reference
4. Depth of Cut – Saws were ranks for cut capacity
5. Charging Time – We ranked the time it took to charge depleted batteries.
6. Ergonomics – Ergonomics is really important to users and an important category to consider when purchasing any power tool.
7. Features – We discuss stand-out features and team favorites
8. Size and Weight – Size matters and weight can get cumbersome. We measured the dimensions and scored weight of each concrete cutter as tested (with Batteries)
9. Best Value – Not ranked.
10. Price – The kit price at the time of publishing.

Concrete Test Blocks

We poured 3,500 psi concrete blocks, 12” x 24” x 4.5″ deep. We made the blocks deep enough for all cutter blades to be able to cut all the way through and allow ¼” for any blade wear.  Each concrete block also had two embedded # 4 rebar running along its length. 

Performance Testing  | Concrete with Embedded Rebar Cutting [Ave. Speed]

Each cordless concrete cutter was outfitted with a fresh battery and manufacturer specific blade. All of the manufacturers insisted on us using their branded blades with their saws, claiming that the blades were designed and optimized for the saw.

Run-time on cordless cut-off saws is important when discussing how battery and gas operate differently.  The number one question we are asked is,  “How do these saws compare to a gas concrete cutter? In order for us to address this question we included the  Husqvarna K770 gas saw as a comparison.

Run-time Test Procedure:

Without a test rig to eliminate these types of variables, it is very hard to have a controlled test. Technique is important and we recognize that we needed to let the tool do the work and not bog it down, which is why we designed our tests with the following criteria:

1. All 4 battery saws had two sets of fresh batteries and new Manufacturer blade.
2. The Husqvarna K770 had a full tank of gas and a fresh Milwaukee Diamond blade.
3. 4 operators per saw.
4. We used the 24″x12″x4.5″ concrete test blocks.
5. Each cut was timed and recorded.
6. Water was used on each cut.
7. Each operator made 3 cuts and swapped out to prevent fatigue. [Fatigued users tend to lean on the saw]
8. Every operator employed a “stepped” cutting method.
9. Every operator let the tool do the cutting, and listened to the motor for feedback. Operators applied pressure when the tool would allow it, and if the motor seemed like its bogging down they let up on the pressure.
10. The test ended when the saw battery died, and when the K770 ran out of gas.
11. The total slices [including partial cuts] were recorded for a total lineal foot measurement.

Note – The Husqvarna K770 gas saw has a fuel tank capacity of 0.95 qt.

Note on Step Cutting:

Step Cutting, also known as incremental cutting, involves making multiple incremental cuts with the saw until the overall desired depth of cut is reached. The number of cuts taken to reach the desired depth depends on the material being cut, the saw’s horsepower, and the operator’s experience.

• Step Cutting Increases Cutting Efficiency
• Step Cutting Increases Blade Life
• Step Cutting Results in Cleaner, Straighter Cuts

Note on Run-time Testing

With any cut-off saw you will experience varying results based on the material you’re cutting, you’re cutting style, operator experience, blade used, etc.  Ambient temperature also affects run-time. The more demand you put on the motor, for example leaning into the saw too much, the more Amps it will pull from the battery to keep the power output. The same effect can happen with a gas saw, except run-time is just not usually taken into consideration given the quicker refueling vs. recharging time.

Run-Time Testing | Winner –    Husqvarna

In all cases, it is necessary to supply two sets of batteries in order to compete with the expected run-time of a single tank of gas, on a gas saw. Manufacturers recognize this, and most are starting to sell these saws as a kit with two sets of batteries

The Husqvarna concrete cutter was able to complete 36 cuts, or 36 linear feet, in the concrete blocks, compared to the K770 gas saw which completed 30 cuts (30 linear feet). Second place was the Hilti cut-0ff saw with 29 cuts (29 linear feet), followed by the Makita with 24 cuts (24 linear feet) and Milwaukee with 23.5 cuts (linear feet).

One interesting fact was the average speed to complete these cuts.

The gas K770 saw completed 30 cuts  [30 lineal feet] with an average speed of 35.5 seconds.  The Milwaukee which brought up the rear with the least amount cut, was powerful enough to cut the concrete blocks even faster than the gas saw at 34.9 seconds.   The Husqvarna cut an average of 40.7 Seconds and both the Hilti and Makita tied with 45 seconds.

Note – photos in this article show K1 Pace with a smaller battery. This saw was photographed, and tested with a smaller battery, and later that week, tested again with a larger battery. The stats in this article are from the larger battery.

Watt-Hours Per Cut

While many sectors of the power tool industry have transitioned to battery power and cut the cord, there remains some specific tools like cut-off saws (concrete cutters) where there is no cord to cut.  Instead the power source is a small engine that runs on gas.  In order for the cordless cut-off saws to compete with the gas power standards, they need to not only have similar cutting power but also carry enough potential energy on board to get the job done. 

With all the tools running at different voltages, the quickest way to get a snapshot of how big a “gas tank” the tool has is to see how many Watt-Hours the batteries on board have.  We ran our endurance test with one battery swap so Watt-Hours are doubled in the chart.  By calculating Watt-Hours per cut we can get a good idea of how efficient the tool is at transforming that battery potential capacity into concrete cut. 

The Husqvarna had the largest battery of the group which helped it achieve top rank of cuts.  But it was also the second most efficient at using its “gas tank.” The Hilti had the least amount of Watt-Hours but cut the second most amount and was a standout as the most efficient with 35.17 Wh/cut.

The Makita and Milwaukee have exactly the same Watt-Hours on board and cut almost an identical amount concrete.  The Makita edged out a half cut over the Milwaukee which translates to a lower Wh/Cut value of 48.00.

An interesting observation when comparing the efficiency ranking of the tools is to compare them to the following speed and power rankings.  It’s clear there are always design tradeoffs between power and efficiency and these tools are no exception.

Performance Testing  |  Rebar Cutting [Ave. Speed]

Each cordless cut-off saw was outfitted with a fresh battery and the same brand specific abrasive cutting disk. One operator was used to make three cuts in five ganged #4 rebar for an average time.

Speed Test Procedure:

1. The same operator and timer teamed up to make 3 through cuts in five #4 rebar.
2. Each cut was timed separately.
3. The operator pushed as hard as the saw would allow.
4. The three cuts were averaged and scored.

Fastest Rebar Cutting |  Winner – Milwaukee

The Milwaukee was able to cut through five #4 rebar in. 7.78 seconds. Second place was the Makita at 10.3 seconds, and third was Husqvarna at 16.4 seconds, Hilti fourth at 17.0 seconds.

The team felt that this test, with all of the saw using an identical blade, was a great indicator of the available cutting power.

Depth Of Cut | Winner – Husqvarna

The depth of cut on a saw is important to all users. Husqvarna had the deepest depth of cut with 5-5/8 inches. Second place was the Makita and Milwaukee both with 5 inches, followed by the smaller Hilti saw at 4-3/4″. Husqvarna’s unique design where the arbor is offset from the drive band allowed for this impressive cutting depth.

Power Cutter Ergonomics | Winner – Husqvarna

The ergonomics evaluation in this section is purely subjective and based on the opinions of the testing crew. After a full day of running performance tests, the team sat down and ranked each tool in several categories on a score of 1-4 [1 being the best]. For the ergonomics evaluation, the team evaluated the following criteria:

1. Grip
2. Balance
3. Line of Sight
4. Vibration
5. Blade change
6. Battery change

The Husqvarna was the clear winner and a team favorite with final ergonomic score of 9. It won three categories with top score for grip, balance and line of sight.

The team did not like that the Husqvarna does not have rollers but all agreed that it had excellent vibration damping, excellent balance, was the smoothest cutting and its streamlined design contributed to its excellent line of sight. It was very obvious to the team that Husqvarna has been making these cutters for a long time, and the form factor of their battery powered and gas powered saws is very similar.

Second in ergonomics was a tie between the Hilti and Milwaukee. Hilti took tops in vibration, and scored second in balance. Milwaukee came in second in grip, line of sight and blade change.

The team liked the Hilti grip and balance and felt it had a really good line of sight. All of us felt that it was a smooth cutting saw  and was one of the easiest saws to start and operate. The only criticism was that the batteries tucked under the tool and are not as easy to insert or remove compared to the others.

Milwaukee is a powerful cutting saw that you can lean on. It has a nice grip, excellent line of sight, great balance, good battery removal but is a bit bulky and heavy.  The Milwaukee saw has no visible decoupling  but had surprisingly low vibration. Milwaukee does isolate the drive systems gear box to minimize vibration.

Makita which scored tops in blade change and had very easy battery changes. However its bulky size, weight, and uneven balance hindered its ergonomics score. The Makita had the easiest blade change, was a super powerful saw, it was the only saw that you never had to back off on while cutting.

While cutting concrete the Makita seemed to vibrate quite a lot. However when more force was applied the vibration lessened considerably. Basically the user was forced to “preload” the decoupling spring to prevent blade chatter. This seemed to be a non-issue in rebar cutting and led us to wonder if it was due to the blade more than the saw itself.

Cordless Concrete Cutter Features | Winner – Hilti

We considered 8 features on these cut-off saws:

1. Tool Activation
2. Water connection
3. Decoupling [vibration]
4. Blade Brake
5. Wheels
6. Handles [Multiple Hand Placement]
7. Indicator Light
8. Arbor Lock
9. LED Light

Hilti took first place in features with a top score in tool activation, blade brake, had the best wheels, and second best water connection. Second place went to the Makita with a well designed arbor lock, water connection and the only saw to feature an LED light. Third place in features was a tie between Husqvarna and Milwaukee.

Husqvarna has an electronic brake called “X-Halt,” which  stops the blade in a fraction of a second if a kickback occurs. The function cannot fully prevent personal injury from a kickback, but it decreases the risk.

Husqvarna had the most informative user interface, great decoupling and tool activation.  It will also time out [turn off] after 3-minutes, a time period we feel is too short.

Makita had the best auxiliary handle in terms of the amount of usable space or hand positions. It is also the only tool in the test to feature a push-button arbor lock.

Makita is equipped with “Active Feedback-Sensing Technology,” which electronically turns off the motor if the rotation of the cutting wheel is suddenly forced to stop. It also features Extreme Protection Technology, which is engineered for improved dust and water resistance.

No one on the team liked how the Makita lock-off button is actuated. This single-sided safety switch  [set up for right-hand thumb] is difficult for left-handed users to activate. Instead of a safety switch integrated into the palm grip which naturally gets depressed when holding the tool the users must push this button with their thumb 90 degrees offset to the spine of the tool. It’s neither intuitive, nor comfortable to actuate, and we all fumbled with it.

Milwaukee had a fantastic blade brake, and incorporates their RAPID STOP technology to help prevent damage from kickbacks and unexpected handling behavior. It has a unique trigger activated water valve which turns on or shuts of the water with the trigger.  This initially received high praise from the review team but later in testing proved to be a hindrance due to erratic behavior likely due high water pressure.

The Milwaukee states in the manual that the MAX water pressure for the tool is rated for 60 psi. We measured 97 psi at our test site. Milwaukee needs to address this, as contractors do not want to add an additional accessory, like a pressure reducer, to their set up.

Bluetooth Functionality

Husqvarna has built-In connectivity for asset management, allowing you to monitor location, run-time, service intervals and receive wireless updates.

Milwaukee has One-Key connectivity which allows for fleet management, location tracking and lockout.

Power Cutter Weight | Winner – Husqvarna.

Weight can cause fatigue with cut-off saws. The lightest saw was the Husqvarna weighing in at 30.8 lbs. Second lightest saw was the Hilti at 30.1 lbs, third went to Milwaukee at 33.35 followed by Makita at 34.25 lbs.

Note – the Husqvarna K770 gas saw has a weight of  26.12 lbs. without gas.

Best Concrete Cutter Battery Charging Time | Winner – Milwaukee and Hilti

In order to achieve gas saw performance you will need two sets of batteries. The theory is to have a battery(s) on the charger while you are working. This reduces downtime and maximizes your productivity. That being said, will the battery reach a full charge before you need it? The answer to that depends on how much cutting you are doing at one time.

The fastest battery charging time was a tie between Hilti and Milwaukee MX battery, both with charging times of 45 minutes. Its important to note that the Hilti ran off of two B22-255 batteries and to achieve this time you will need two chargers. Otherwise you’ll have to double this time.

Husqvarna was third with a 55 minute time, thanks to its “express charge” feature on the charger. This feature allows the user to press a button on the front of the charger to activate. However, you don’t want to fast charge batteries on a regular basis because it’s hard on the cells. A standard charge time is about 75 minutes. The express charge is there for when you need it. We are based in the North East USA and our electrical system is based on a 110V AC standard.  Its important to note for European customers that the Husqvarna charger is able to perform slightly faster on the 220V AC standard and give a 45 minute express charge.

The Makita dual charger simultaneously charges both Makita 40V 8.0Ah batteries at the same time in 76 minutes.

Best Priced Power Cutter | Winner – Hilti

These four saws are unquestionably pricey tools. In order for these saws to achieve gas performance you will need two sets of batteries. Replacement blades on these machines runs approximately $150.

The Milwaukee and Makita saws are offered in a kit that includes two sets of batteries and a charger. The Milwaukee comes with two batteries, whereas the Makita comes with four (the saw requires two batteries to function).

Our conclusion is that these cut-off saws all require two batteries to match one tank of gas. For pricing we included the saw, two sets of batteries, and a charger for the Husqvarna and Hilti.

The winner of the best price is the Hilti DHS 700-22 priced in our kit form at $2,493.00

• Tool cost: $1,183.00
• 4 batteries:  $243.00 each
• 2 chargers: $169.00 each

Second place was the Makita Power Cutter Kit totaling $2,699.00 and third was Milwaukee, sold as a kit for $2,999.00.

The most expensive cut off saw was the Husqvarna which when added all together was $3,996.00. This extremely high price is due to the cost of the batteries. The B750X battery is $939.00 each and when adding in two of them it contributes 50% of the total price. At this cost users could almost purchase two competitor saws for the price of the Husqvarna.

Overall Best 14″ Cordless Cut-Off Saw (Concrete Cutter) | Winner – Husqvarna

Its important to note that ALL of these cut-off saws performed well and were extremely close. Two of the manufacturers Hilti and Makita also have huge power tool platforms that their batteries will interchange with.  The other two Husqvarna and Milwaukee, only have a few dozen tools currently that their batteries will power.

The overall Best Cordless Cut-Off Saw in our testing was the Husqvarna with a score of 21.  Hilti came in second with 23 and Milwaukee just one point behind with 24.

Note: Given the number of categories scored for our overall ranking we decided to double the value of our performance tests.  Both the Concrete Endurance and Rebar Speed scores were multiplied by a factor of 2 in the final chart.  We feel that the cutting endurance and cutting power of these tools carry the most weight and importance to the potential end user.

The Hilti saw is technically a 12″ power cutter, had the shallowest depth of cut, but clearly punched above its weight in this test with a great feature set, low weight, and impressive run-time and speed scores.

The Husqvarna K1 Pace power cutter was a team favorite and a clear winner with top scores in five out of nine categories. It is a lightweight, well balanced cut off saw with great runtime, functionality and line of sight.

The Makita saw was heavy and powerful. It was the only saw we NEVER had to let up on and you can actually lean into cuts with. It has excellent features and ergonomics, a generous depth of cut and was second fastest in our metal cutting test.

The Milwaukee MX saw is a Gen 2 saw and was a speed demon when cutting metal averaging almost 3-seconds faster than the next concrete cutter. It too was a powerful cutter with an excellent depth of cut, great price with good features and ergonomics. The water connection issue hurt the MX saw and kept it from standing alone in 2nd place.

Best Value Cordless Concrete Cutter | Winner – Hilti and Milwaukee

Best value is typically awarded to the saw that performed well and is lowest or low in price. The Hilti and Milwaukee were close in scores and $500 apart in cost. With regard to performance the Milwaukee power cutter performed slightly better than the Hilti. One tool did well in concrete endurance, and the other in cutting speed.

The Hilti cordless cut-off saw surprised us all in its performance and frankly price. Hilti has historically been at the top of the pricing charts in all of our head-2-Head tests. The bottom line is both concrete cutters have great feature set, good ergonomics, and excellent charging times which is important to keep you in the “cutting” game.

Either of these cutters are great! ~ Rob

Closing Thoughts

The biggest issue with cordless cut-off saws is charge time. It’s our opinion that contractors who cut concrete with 2 tanks of gas or less a day are in the “sweet-spot” to convert to a battery power cutter.  If you are cutting all day and using 5 to 7 tanks of gas you should stay with a gas cutter or invest in more batteries.

Speaking of batteries, the Hilti and Makita tools both use batteries that are compatible with a wide variety of smaller tools (Hilti’s Neuron line and Makita’s 40v XGT line). This could be a factor in purchasing decisions.

Lastly, charge time, and power to charge is a consideration.  Many of these batteries require 45 minutes to charge, and  you also need to consider how remote you are working. Do you have access to electricity or an inverter to charge your batteries?

We get lots of comments about how we make the final rankings. There are dozens of ways to compare tools, our goal when testing is to achieve repeatable, consistent results. We share ALL the data from our tests, so you can re-rank the tools however you want. If you don’t care about an item we ranked? No problem. Remove that from the matrix above and re-rank them.

Hopefully you’ll find this Head-To-Head useful when considering purchasing a larger cordless power cutter, or comparing them to gas models.

Greenworks 12-Inch Cut-Off Saw [Power Cutter]

We recently looked at the Greenworks 12-Inch Cut-Off Saw . The 12-inch Greenworks cutter is powered by an 82V 3.2kW battery platform. The beauty of a battery power cutter set up like the Greenworks is all you have to do is insert a battery and start cutting. There is no pull start, 50:1 gas ratio, spark plug, stale fuel or clogged air filters.

Greenworks currently is offering 4 battery sizes, we tested our unit with w 4.0 Ah battery.

First Impression | Greenworks 12-Inch Cut-Off Saw

The Greenworks 12-Inch Cut-Off Saw is a brushless, direct drive, zero- emission power cutter that allows users to work indoors without the worry fumes. It is compact and seemingly well built. This 82 volt cutter has a 4.3″ depth of cut and is lightweight and well balanced.

The LED light on the blade guard is a nice feature, we wondered, due to its proximity to the blade if slurry splatter would build up and obscure the LED during our testing. It did not!

Operating the saw is simple and intuitive with an electronic power button, safety switch and trigger.  This two-step process to turn on and off the tool is easy to follow and we liked the simplicity of it.

Testing the Greenworks 12-Inch Cut-Off Saw

The cutter has a deeper cut than other competitor 12″ gas saws, 4.3 vs 3.9 inches, and we liked that the 4.0 Ah battery charges in 30-minutes. We tested the Greenworks 12-Inch Cut-Off Saw in several materials: concrete with embedded rebar, metal pipe and rebar.

Metal Cutting Test

Outfitted with a fresh battery and abrasive cutting disk we used the Greenworks cutter to cut metal pipe, and five #4 ganged rebar. The cutter made fast cuts and was easy to use. 

Concrete Test Blocks

We poured 3500 psi concrete blocks, 12” x 24” x 4.5″ deep for a Head-to-Head test we were working on, so it made sense to use the same blocks to test the Greenworks concrete cutter. Each concrete block also had two embedded #4 rebar running along its length.

Note – the Greenworks cutter was not able to cut all the way through our test blocks. We maxed the cutter out for cutting and counted the slices completed.

Performance Testing | Concrete with Embedded Rebar Cutting [Ave. Speed]

Run-time on cordless concrete cutters is important when discussing how battery and gas operate differently.  The number one question we are asked is,  “How do this saw compare to a gas power cutter? In order for us to address this question we included the Husqvarna K770 gas saw as a comparison.

Run-time Test Procedure:

Without a test rig to eliminate these types of variables, it is very hard to have a controlled test. Technique is important and we recognize that we needed to let the tool do the work and not bog it down, which is why we designed our tests with the following criteria:

1. The Greenworks had two fresh batteries and new diamond cutting blade
2. The Husqvarna K770 had a full tank of gas and a fresh Milwaukee Diamond blade
3. 4 operators per saw.
4. We used the 24″x12″x4.5″ concrete test blocks
5. Each cut is timed and recorded.
6. Water was used on each cut
7. Each operator will make 3 cuts and swap out to prevent fatigue. [Fatigued users tend to lean on the saw]
8. Every operator will employ a “stepped” cutting method.
9. Every operator will let the tool do the cutting, and listen to the motor. Operators could apply pressure if the tool would allow it, and if the motors seem like its bogging down they were to let up on the pressure.
10. The test ended when the saw battery died, and when the K770 ran out of gas
11. The total slices [including partial cuts] were recorded for a total lineal foot measurement.

Note on Run-time Testing

With any power cutter you will experience varying results based on the material you’re cutting, you’re cutting style, operator experience, blade used, etc.  Ambient temperature also affects run-time. The more demand you put on the motor, for example leaning into the saw too much, the more Amps it will pull from the battery to keep the power output. The same effect can happen with a gas saw, except runtime is just not usually taken into consideration given the quicker refueling vs. recharging time.

Cutting Results | Greenworks 12-Inch Cut-Off Saw

We made 14 cuts in concrete [14-lineal feet] before draining both batteries. The Husqvarna K770 gas saw completed 30 cuts/feet and was able to cut completely through the test blocks. We recognize that we were cutting with a 4.o Ah battery and had we had the 8.0 Ah battery to test we probably would have had 28+ cuts. and be much closer the the K770 saw.

We did notice that the Greenworks 12-Inch Cut-Off Saw if pushed too hard can be bogged down and it was important to let this tool do the work and not bear down too hard.

The reality is that with two batteries, the Greenworks cut-off saw can compete with a gas saw.

Improvements

If we were to offer Greenworks advice on improving their saw, it would be the water connection. The saw has a flexible water hose which makes one-handed hose connecting impossible. We recommend that the water connect be mounted to the side of the saw as a solid connection.

Price and Where To Buy

The Greenworks 82 volt power cutter costs $439.99 as a bare tool, and $699.99 as a kit. The kit includes:

• 82V 12″ 2.5KW Power Cutter – 82PC12
• 12″ Diamond Blade
• 4Ah Battery
• Charger

I included the Greenworks graphic below because it tells an interesting story comparing cost of ownership between the Greenworks saw and a gas power cutter.

Final Thoughts

We enjoyed using the Greenworks concrete cutter and all agreed when paired with a 4.0 Ah battery its best suited for lighter masonry work such as cutting pavers. If you plan on cutting basement slabs open, or doing any full depth concrete cutting, then we recommend pairing it with an 8.0 Ah battery.

We think that battery power cutters have their place, especially when remodeling indoors. It’s our opinion that contractors who cut concrete with 2 tanks of gas or less a day are in the “sweet-spot” to convert to a battery power cutter.  If you are cutting all-day and using 5 to 7 tanks of gas you should stay with a gas cutter or invest in more batteries.

I was worried that one of two limitations would happen, either 1) the battery would overload and the chop saw would auto-shutoff mid-cut or 2) the battery would run down too quickly making the cordless saw less effective (and less useful) than its corded cousin. Thankfully, neither limitation occurred. The 2990-20 chop saw cut and kept cutting as advertised and required.

The Battery life was a strength and not a limitation at all. While the saw doesn’t come with a battery out of the box, Milwaukee recommends using an M18 HD12.0 battery for peak performance. As is standard with most newer chip-enabled power tools, the HD battery line-up enables peak saw performance by optimizing cutting operations between the saw and battery. The first day I cut 2 x 2 x 1/8″ angle iron and 1 1/4″ Schedule 40 pipe intermittently for about 2 hours while doing trailer repair and handrail fabrication jobs. At the end of cutting I still had 2 bars left on the battery. The battery life was also optimized in part by not overloading the saw via the REDLINK PLUS overlight light.

So what is the REDLINK PLUS Intelligence & overload indicator light? Simply explained it’s an integrated light in the handle of the saw that lets you know when the voltage draw from the battery is exceeding the recommended max draw and could potentially be adverse for the brushless motor. Even more basic, cut as hard as you want until the red light turns on and then back off a bit. It was easy to use and gave peace of mind that I wasn’t overtaxing the motor. Because what PRO wants to invest in a new job-site tool only to burn it out sooner than expected? This is a great and simple feature to optimize the 2990-20’s cutting performance!

Ergonomics and Design Features

So the Milwaukee 2990-20 Chop Saw cuts well. But is it well designed from a user standpoint? Yes. Two features made it very user-friendly; The well-placed top-mounted carry handle and the overall tool-free adjustability. The carry handle is well placed and balanced. This may seem like an easy takeaway but not all handles are equal. Because the base is flat on both sides parallel to the saw handle, there was no instance of knee-knocking into the motor or blade assembly. The saw side comfortably rested against my upper leg regardless of carrying left or right-handed (yes I tested out both). The weight was also well balanced when carrying without the battery mounted. With the battery on it, the chop saw was a little back heavy but I prefer to carry tools without the battery loaded to and from the job site.

The Milwaukee 2990-20 Chop Saw was also easily adjustable without tools which is essential for job site performance. There are a number of standard features: an integrated blade change locking button (to the right of the handle), quick release flip-up threading, and a tool-free adjustment to the miter angle. Even moving the backstop either forward or backward can be done tool-free, although there is an integrated Allen wrench for really tightening the locking bolt 100%. The only adjustment that requires a tool/feature not integrated into the 2990-20Chop Saw is the depth stop bolt. It requires a wrench to adjust. Overall adjusting the 2990-20 Chop Saw is a breeze and offers sturdy settings once locked in place.

I was also a big fan of the placement of the battery mostly due to the easy-to-use battery indicator status light. Sometimes the battery indicator light is awkwardly located on the backside of a tool. THis is not the case with the Milwaukee 2990-20 Chop Saw though. It was extremely easy to check the battery in the middle of cutting!

Safety Features

So the Milwaukee 2990-20 Chop Saw cuts well as is easy to adjust. But is it safe to use? Also, yes! The true test on job site performance is safety and we at Tool Box Buzz have always placed an emphasis on safety first and doing things right even when no one is watching. With those standards in mind, the Milwaukee 2990-20 Chop Saw again stood out. It has 3 safety features that make it safe and reliable to operate:

• RAPID STOP Brake
• Blade guard
• Spark guard

These 3 features mean that the blade stops when you want it to, and while it’s running it offers safe cover and control of both the blade and the sparks it produces. The last thing you want is to have accidental cutting or contact with a blade that’s still turning after letting go of the trigger. The RAPID STOP brake excelled mostly because it actually rapidly stopped the blade. The blade guard worked well and was of a pretty standard design. It was easy enough to pull back when changing the blade and protected the blade well from upright to fully lowered blade positions. And the spark guard did a great job of redirecting almost all the sparks downward toward the ground allowing for great mitigation of fire starting risk. Overall these safety features worked well.

Final Thoughts | Milwaukee 2990-20

There is really nothing but positive things to say about Milwaukee’s M18 FUEL Chop Saw (Model 2990-20). It performed exceptionally, was easy to adjust on the job site, and offered well-performing standard safety features. It’s a great addition to the M18 family of tools and a no-brainer for any PRO already using the M18 lineup. And if you haven’t committed to a cordless brand yet and are in the market for a 14″ abrasive chop saw, then the 2990-20 Chop Saw is likely the saw that will get you hooked on the Milwaukee M18 lineup. At $400 this tool is an investment but certainly, a smart one you won’t regret!

Milwaukee MX FUEL Equipment On My Job (An Ongoing Series) -The 14″ Cut-Off Saw

MILWAUKEE MX FUEL 14" CUT-OFF SAW 2 BATTERY KIT W/ ONE-KEY MXF314-2XC

4.5/5

Manufacturer: Milwaukee
Price: 2,499.00
Power source: MX FUEL Battery
Motor size: 5350 RPMs
Weight: 32

In this review, I’m going to focus on my experience with the MX FUEL 14” Cut-Off Saw. But make sure you check out the article about my experience with the MX FUEL Core Drill as well!

A Monday Morning-Type Problem, Right?

“What do you mean you can’t get the concrete coring subcontractor out here until Thursday? I’m dead in the water until I have those cores drilled. And that’s four days from now!”

In the 2021 commercial construction environment where I operate, a real constraint is keeping up with changes and issues that mean getting a concrete slab cut or concrete cores done ASAP. Often, someone has dropped the ball or realized they need to react to the situation immediately. Mostly, these kinds of issues are not significant in scope but are undoubtedly large in impact. This is especially the case if the GC contract has Liquidated Damages or other punitive clauses for failing to meet the schedule. That is why getting these seemingly small items done right away can be critical to an organized and effective workflow.

Wishful Thinking

Certainly, I wish that people would plan better so that these kinds of issues do not pop up.  However, I think we will solve global warming or world peace long before getting people to plan proactively.

Bur rather than accept the time delays, I now have a great option with Milwaukee MX FUEL equipment. I can call on these battery-powered tools when I need some quick turnaround on concrete cutting and coring. The Milwaukee MX FUEL equipment are a key to solving such pressing job site problems.

First Call for the MXF314-2XC  Cut-Off Saw

Earlier this month, I received two Milwaukee MX FUEL  tools on my jobs to evaluate their use and performance. I had the equipment less than one week before I put them to productive use.

First, my crews used a 14″ cut-off saw to open up asphalt streets for digging test pits that the engineers recently requested. The engineers needed additional information to complete their work and the entire project was on hold until they had the test pit information.

With the MX 14″ cutoff saw, my crew was able to start cutting up the street within minutes of when the request came in. Most importantly, I did not have to wait the three days for a specialty subcontractor to get to the site. In addition, we did not have to run to the gas station or find the two-cycle oil to mix up the correct ratio of gas-to-oil. We plugged in a charged battery and started up the saw and a battery-operated Milwaukee tank and pump. The guys started cutting up the pavement right as our vac truck backed up to the site.

Milwaukee MX FUEL Cut-Off Saw Performance

The Milwaukee saw performance tracked the Milwaukee-suggested performance. It is as fast as a conventional gas-powered saw. This MX FUEL saw delivers the power to provide a best-in-class cutting solution. Milwaukee has a table of anticipated lineal feet to expect from a fully charged battery. I have copied the factory data in the table below:

A Great Solution for Confined or Interior Spaces

The battery-powered equipment does not have the run-time to match a gasoline-powered saw. But the crew remarked that they like the idea of a battery-powered saw in a confined space. These guys often work inside of manholes or in deep trenches. The same goes for cutting in an interior space. Also, one crew member said how much he liked the idea of 100% certainty that the saw will start, no matter what the temperature is at the site. There was no more pulling, choking, wasted time, and colorful language needed to start up the cutoff saw.

Our field experience tracked in agreement with the factory data. We had four fully charged batteries available, and we cut 28 linear feet of street asphalt with three batteries depleted fully and one battery with 50% charge remaining.  Each of the crew that used the saw was impressed with the electric motor’s torque and power. “This Thing is a Beast” one of the crew said multiple times (some language censored out of that quote).

The Milwaukee 2819-21WS  Water Supply Kit in a Remote Location

Part of the challenge with remotely located asphalt cutting is how to provide a consistent flow of water onto the blade. In our case, we had a great Milwaukee accessory to use with the saw. I own a 2820-21WS M18 Switch Tank Water Supply Kit. I used this tank during a Tool Box Buzz 9-inch cordless cutoff saw comparison. In our MX FUEL equipment use case, this tank came in very handy and married up to the MXF314-2XC saw with no issues.

This tank is a great solution. It holds 4 gallons of water and contains a battery-operated pump. The M18 XC3.0 battery can power the tank through 12 full tanks of water. Users can adjust the 2820-21WS pump through a range of 20 psi to 60 psi. The quick connector coupling on the end of the 10 feet of hose clipped onto the 14 “cutoff saw with no issues.

To cap off one of the most significant features of the 2820-21WS water supply kit, it helps users will comply with the OSHA Table 1 requirements for dust mitigation. For inside or confined space work, the 2810-21WS enhances safety and cleanliness.

Water Source

We had a very convenient source of water from the onboard water tank in the vac truck at the job site. That water source allowed the crew to refill our Milwaukee pump. The work crew usually splashes water from a 5-gallon bucket onto their cutoff saws in the past. In our setup, we had a tank/pump combination with a variable flow adjustment. Our equipment configuration meant a much more steady water source that flows water directly onto the cutting blade. The crew was impressed with the entire equipment setup.

MXF314-2XC Has Great Wheels – Way Easier on our Backs!

One of the best-liked features was the wheels on the bottom of the saw. That meant the crew did not need to support the saw’s weight as they would need to when they use their gas-powered equipment.

The pavement supports the weight of the saw. The crew used their efforts to control the plunge cut’s depth and the speed of advancement. They remarked about the lack of fatigue and strain on their backs. Even our safety personnel seconded that observation and noted the process improvement and potential reduction of lost-time back injuries using the Milwaukee MX saw.

The Milwaukee equipment allowed us to get a timely start on opening the roadway and start excavating the test pit with no delays. While the runtime of a battery-powered piece of equipment will not match up to that of a gas-powered cutoff saw, the MXF314-2CX goes toe-to-toe with power and torque. The added convenience of instant start and no exhaust fumes and engine noise put this saw way above the gas-powered equipment. Great engineering features like the wheels on the bottom and the accessory tank make the Milwaukee MX FUEL system a compelling investment. It is going to be my go-to equipment for light-duty quick turnaround projects.

Final Thoughts – Milwaukee MX FUEL Cut-Off Saw

An investment in Milwaukee MX FUEL equipment is a lot of money for any contractor. The MXF314-2XC cut-off saw with two of the XC406 batteries and charger will run online for around $2,500. Is this kind of investment justified for a commercial contractor? My personal answer is an unqualified – YES.

Here is why the MX Equipment is Worth the Investment.

In my company, we hit the start of a job very hard because our experience has shown that getting a job underway is often a slow ramp-up. But in my case, I push the job start as the most critical time in the job because it is the time where I can make up or better the time in the schedule at a minimal cost. Tell me which is easier. Saving (or not losing) time when you have about 12 guys and two subcontractors present, or scrambling to save time when you have 150 personnel and 15 subcontractors tripping all over themselves near the end of a job? At the end of jobs, I have seen contractors and owners throw barrels of money away just to save (or pick up) a few days on the schedule. Those dollars are often spent with questionable actual results.

But let me bring the discussion back to the case at hand. My current job has liquidated damages clause that would cost my company an amount that equates to $2,095/ workday.  With the Milwaukee MX FUEL equipment, I avoided wasting three days on the roadwork to start the test pits. I also avoided another three days of delay in starting  the electrical conduit work. Both of those delays would cost me valuable time at the critical start of the job. by my calculations, having the Milwaukee MX FUEL equipment available to go with minimal startup timing was worth $12,600 to me. That value is just shy of 2 times what the equipment initially cost.

Many Many More Uses

In the future of this project, I will guarantee that both of these pieces of equipment will be used repeatedly during the next 25 months. So right out of the box I saw that the investment was more than paid off and the rest of the use will be additional justification for having made the investment in this Milwaukee MX FUEL Equipment.

Both the MXF314-2XC 14″ cutoff saw and the MX301-2CP Core Drill saved us extremely valuable time in the critical start of the job. Also, the Milwaukee 2819-21WS  Water Supply Kit aided in delivering water supplies to both machines. Both of these use cases were in remote locations that did not have an external power sources or water feeds available. With this equipment system, the work proceeded as soon as we showed up with the equipment. These real examples are why the MX line of Milwaukee tools is an excellent investment to save time and money in the commercial contracting world.

Now if I only had gotten ahold of the Milwaukee MXF368-1xc Breaker, I would not have had to rent that jackhammer and air compressor…… Stay Tuned…

Check Back for More!

Like I mentioned, this is the first of two MX FUEL products I’ve gotten a chance to try. Hopefully, over time as the MX FUEL System grows, I can try out some more and report back!

Milwaukee M18 Fuel 9 Inch Cut-Off Saw –  Feature-Rich

The Milwaukee 9-Inch Cut Off Saw is a new tool to the Milwaukee lineup and the designers were paying attention to the market and created a cut-off saw that competes well. We especially liked the friction glide adjustable guard that the user can adjust to any position without having to use any pre-set detents. This feature allows a lot of flexibility in how the saw fits with workpieces and the user stance.

The Milwaukee is the only saw that offers the One-Key system. This feature allows users to track the location of their tool; allows the user to lockout/disable the saw out from unauthorized users and the One-Key app offers a tool inventory management function as well.

Onboard Tool Storage

Milwaukee stores two tools in a convenient location at the rear of the tool; a spindle wrench and an Allen wrench. To change the blade, one feature we liked is that once the user indexes the Allen key into a hole in the shaft, it locks the shaft in place. That way, the user has a free hand to assist in removing the arbor nut and installing the blade.

Wet Saw Features

The hose connection on the Milwaukee M18 Fuel 9 Inch Cut-Off Saw has a nickel-plated aluminum ball valve attached to a PVC-reinforced Nitrile Butadiene Rubber hose. Because Milwaukee mounts the hose on the outside of the tool housing, the user needs to be careful not to snag the hose.

We did like the metal valve for its ruggedness. The water supply hits both sides of the blade and delivers a sufficient amount of water to assist in wet cutting operations.

Heavy Load Indicator Light

Milwaukee provided a heavy load indicator on the top of the tool housing. The heavy load indicator provides real-time power and run-time feedback to the user during demanding applications. According to Milwaukee, this light tells the user that the tool is pushing past its optimal cutting power and that pushing harder on the cut-off saw while the indicator is lit will not provide more performance, However, it will significantly reduce the run-time battery life.

The Milwaukee Cut-Off Saw is belt driven and is very smooth and vibration-free.  Long sessions with the tool will have the users welcoming the very low vibrations due to the belt-driven blade. Of the saws tested, the Milwaukee was the smoothest with a vibration reading of 1.8 m/s². This reading was substantially less than the other saws.

Safety Switch

The Milwaukee Cut-Off Saw uses a dual-trigger, which encompasses a small trigger safety- spring flap on the main trigger. The spring-loaded flap that needs to be depressed before activating the trigger.

Milwaukee M18 Fuel 9 Inch Cut-Off Saw Price

Bare tool pricing for the Model 2786-20 starts at $599.  The Kit, offered at $899.00 includes a charger and two 12.0 Ah batteries. This is a larger size than the battery sized offered by the other kitted tools we tested in the Head-To-Head review. The 12.0 Ah batteries add to the overall value of the kit.

Milwaukee M18 Fuel 9 Inch Cut-Off Saw – Final Thoughts

The Model 2786-20 is a great system to cut masonry, concrete, and steel with a tool that is fully compatible with my M-18 battery system. Surprisingly, the M-18 cut-off saw will do most of the same things that a gas saw performs until you get to the upper limits of the tool’s capability.

I welcome this cut-off saw to my stable of tools. I may not need the Model 2786-20 every day, but I sure am glad I own one when the need arises. It an excellent value and capable machine. I have a cordless cut-off saw that is an extremely versatile solution for cutting a large variety of materials without the hassles of a traditional gas-powered saw. That is a win in my book!

Husqvarna 9 Inch Battery Powered Cut-Off Saw

Husqvarna 9 Inch Batter Powered Cut Off Saw K535i

3.5/5

Manufacturer: Husqvarna
Model number: K535i
Price: $599 Bare Tool
Power source: 36V 9.4ah Liion
Weight: 7.7 lb w/ bat

We recently tested the Husqvarna 9-inch 535i Off Saw as part of our Best 9 inch Cut off saw Head to Head.    The K535i performed well and is a great lightweight option for small to medium masonry and metal cutting tasks.  The Husqvarna 9-Inch Cut Off Saw K535i is powered by Husqvarna’s 36V Lithium Ion battery platform.

Husqvarna 9-Inch Cut Off Saw Specifications

• Cut depth:  3″
• Blade Diameter 9″
• RPM:  5,940
• Blade Arbor 7/8 in.
• Onboard Water Connection: Quick Connect
• Blade brake 
• Fixed Blade Guard
• 36v battery platform
• Tool Length: 22.2″
• Tool Weight (w/ battery):   7.7  lb.

Lightweight and Compact

The Husqvarna 9-Inch Cut Off Saw has some serious power to weight ratio.  This is moslty due to the fact that with the battery installed this saw weighs in at a featherweight 7.7 lbs.  That’s almost 30% lighter than its closest battery powered competitors.  Pair that lightweight with a nice neutral balance due to the centerline battery position and you have a tool that is extremely easy to use.

The handle is has a smaller diameter, a nice gradual curve and is comfortable to use. The handles slight-slope to the side, was no doubt designed to support hand, wrist and elbow comfort. It allows for many hand positions and does an excellent job of providing comfort in overhead use applications.

The Husqvarna 9-Inch Cut Off Saw is belt driven and is very smooth.  Long session with the tool will welcome the very low vibrations due to the belt driven blade.  Vibrations measure at a low 2.1 m/s².

Water Feed System

The Husqvarna 9-Inch Cut Off Saw has a fixed blade guard with integrated dual side water delivery system.  The water hose is made out of PVC Flex and tucks away nicely into a grooved channel but may be susceptible to snagging and damage.

Husqvarna separated the valve knob from the water nipple by placing  high on the tool  giving it a much easier location to reach and activate.  The K353i water delivery system achieves OSHA Table 1 compliance for dust management when cutting concrete and masonry materials.

Battery Features

The Husqvarna 9-Inch Cut Off Saw uses the 36V lithium ion batter battery platform employed by all of Husqvarna’s battery powered tools. The battery is side-fed and positions itself centerline with no additional covers or compartments.  This open air cooling helps prevent overheating, something we saw in other similar tools during our Head to Head testing.

The battery comes with Husqvarna’s savE feature that allows the user to limit electric motor RPM in the effort to save battery and improve runtime during low load tasks.

Safety and Ease of Use Features

The Husqvarna 9-Inch Cut Off Saw has an on / off keypad switch that will time-out with 1 minute of non-use.   After this 1 minute period the keypad will have to be powered on again.  The rear handle also has a “power trigger lockout safety switch”, similar to other Husqvarna power tools.

The Husqvarna 9 Inch Battery Powered Cut Off Saw features an electric blade brake.  For increased safety and ease of use, the blade will stop its rotation – from full throttle to zero in 3.1 seconds.

The K535i  provides both a wide metal shoe plate and  two rubber feet to keep the tool from sliding when not in use.

Suggested Improvements

The fixed blade guard is something that could be improved on with the addition of a variable or multi location locking guard.

Price

Bare tool pricing for the K535i starts at $599.  The tested 9.4 Ah battery is sold seperately at $279 and quick charger for $184.99.

Battery Powered 9 Inch Cut-Off Saw – Head-To-Head Test

An abrasive saw, or cut-off saw, is a circular saw which is typically used to cut metal and masonry. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel. Technically speaking this is not a saw, as it does not use regularly shaped edges (teeth) for cutting. In this Head-To-Head we determine 9-inch cordless cut off saw.

9 Inch Cordless Cut-Off Saws

In 2015 Stihl was the first company to introduce a 9-inch cordless cut-off saw. Husqvarna was the second. Both of these saws are 36 volts and have a reputation for impressive run-times but were sorely lacking in power.

Then in 2018 DEWALT introduced the 60V FlexVolt which we reviewed last winter, and have been using on our job sites. Last to market was the Milwaukee in the Fall of 2019.

You might be asking why would you want a 9 inch cut-off saw?

It’s a fair question. The TBB Crew feels that these saws are NOT entry-level tools, but more of an expansion tool for users already on the platform. We refer to them as “80% Tools,” meaning they will do 80% of the tasks a gas tool will do.

Cordless cut-off saws enjoy a great range of applications and “niche wins.” Some examples are; mechanical contractors who use it for fast, super straight cuts in 8” PVC pipe, masonry and foundation contractors like it for the basement drains and “first-pass” door entry cuts. [occupied spaces] And let’s not forget the call back cuts or punch list applications once space is occupied.

Advantages of a 9 Inch Cordless Cut-off Saw

• Fast Ramp Up
• No Gas
• No Fumes
• Less Noise and Vibration
• Lighter and easier to use overhead

The fast ramp up on a cordless saw means that you can still get the power needed for cutting and Go After It!

9 Inch Cordless Cut-Off Saw Lineup

In order to keep the tools in this Head-to-Head somewhat similar, each manufacturer was asked to provide their most powerful battery. The following cordless cut-off saws were included in the test:

1. DEWALT
2. Husqvarna
3. Milwaukee
4. Stihl declined to participate

Best 9 Inch Cordless Cut-Off Saw – Factors Considered

The challenge for any Head-to-Head test is developing the testing and evaluation criteria in order to create a valuable comparison for users. There are hundreds of tests that could be performed, however with limited time and resources for this article we chose tests that we feel give a good baseline comparison.

For this evaluation the tests we selected to give a good relative, measurable comparison of run-time and the speed of cutting. We feel these tests will give you a good baseline on overall tool performance. Clearly run-time is hugely important with high demand cordless tools, and productivity is always an important benefit to consider when buying a cut-off tool.

9 Inch Cordless Cut-Off Saw Comparison Testing

1. Full Depth 3″ Granite block cutting for run-time evaluation
2. Rebar cutting for power and speed
3. Multiple metals and masonry cuts in various materials for ergonomic review
4. Cutting of concrete blocks and bricks

Cut-Off Testing Materials

Several test simulations were used which are considered typical of tasks where a contractor might use a 9-inch cordless cut-off saw for, these simulations include:

1. 1. Cutting concrete block [CMU]
   2. Cutting solid concrete block – this block has a very consistent matrix and is made in large precast batches.
   3. Cutting #5 rebar
   4. Gang cutting 5 pieces of #5 rebar
   5. Full-depth cuts in 3″ granite paver slabs
   6. ¼” thick steel channel stock cuts

Cut-Off Saw Testing Categories

In addition to the simulations, each of the crew members spent time cutting varying materials, to evaluate the cut-off saws independently. Our testing simulations and these individual evaluations were used to determine the Best 9 Inch Cut-Off Saw in several categories including:

1. Size and Weight
2. Features
3. Performance
4. Ergonomics
5. Price
6. Best in Class – derived from the above categories

Size and Weight

WINNER –  HUSQVARNA

The length, width, and height of the cut-off saws were used to determine their cubic volume,  and rank was assigned based on volume and tool weight. In the accompanying graph, the left column is the size ranking of the saw and the right column is the weight of the saw.

The Husqvarna is noticeably smaller and lighter than the other two. Its battery placement is the dead center of the tool and between the users’ hands, making a well-balanced tool.

9 Inch Cordless Cut-Off Saw –  Best Features

WINNER –  DEWALT

The team felt that DEWALT beat out the Milwaukee and Husqvarna by two and three points respectively. DEWALT excelled in the disc guard, water feed, base plate, and battery compartment design.

Milwaukee excelled in their heavy load indicator and tool management [One-Key]. They took the number 2 slot in every other category.  Husqvarna excels in their safety switch, water valve location and lanyard hook. They came in a solid second place in tool management [SavE function] and their shoe plate design.

For each “feature” category, the team ranked the tools 1, 2 or 3, (1 being the best).

Stand Out Features

It’s one thing to tell you we rated the features and throw a number at it. It’s another to explain the differences and give you the detailed information. Below we break down the specific stand-out features on these saws.

Cutting Disc Disc Guard

All three tools have three different disc guard designs, they are:

• DEWALT – 5 positions, lock in position.
• Husqvarna  – fixed.
• Milwaukee – fully adjustable, friction slide.

Both DEWALT and Milwaukee cut off saws have adjustable guards that offer the exact same range of adjustment. The difference is in how the guard is adjusted. The Husqvarna guard is fixed, you get what you get!

The DEWALT uses a 5-position system that allows users to move in position and lock it. Their belief is that this design is best for avoiding future problems. They designed their guard with this motto in mind:

“Living with the tool past a year or two!”

The Milwaukee has a friction glide and allows you to adjust the guard without having to be limited to pre-set detents. Many gas tools have friction adjustments and all work great when new for the 1st year. The problem is that crud and grit get inside the guard and freeze it up – it gets stuck! Let’s face it, no one cleans the guard until its frozen.

Tool Management

DEWALT has a tool tag accessory you can purchase and attach to their saw. Husqvarna has a feature on their keypad called the SavE.  This feature decreases the blade speed [not power] and gives the longest run-time. Milwaukee is the only tool that offered true built-in tool management. They accomplished this with their One-Key system which provides the three options:

• Allows users to track tools that are lost or stolen
• Allows users to lockout the tool from unauthorized users
• Inventory management included in the app

Onboard Storage Wrench

Removing discs is easy on all three tools. The DEWALT stores its onboard wrench in the battery compartment. This wrench should never get lost! The DEWALT has a spindle lock that you hold in with one hand to lock the driveshaft, allowing the user access to the disc arbor nut.

The Husqvarna wrench is excellent but is not stored on the tool.  Husqvarna has the easiest push-button, spindle lock of all three saws. The button has a rubber boot to protect it from slurry and water spray.

Milwaukee stores two tools at the rear of the tool; a wrench and an Allen wrench. The Allen wrench indexes into a hole to lock the shaft, freeing your hand up, and allowing the user access to the disc arbor nut.

The team felt that while Husqvarna has the best spindle lock and a 1-wrench system, not having onboard storage was a massive drawback. The DEWALT 1-wrench system onboard storage and spindle lock approach was simpler than Milwaukee’s two wrench approach. They also felt that was much less of a  chance of losing the wrench given it is stored inside a latched battery compartment.

The nice thing about the Milwaukee is that once the Allen wrench is indexed, you can let go of the wrench – freeing one hand. The DEWALT arbor lock needs to stay depressed, if you let go of the arbor lock and move the blade slightly it will disengage.

Water feed

All three saws have water feeds on both sides of the saw – some companies offer only one side.

The DEWALT tool was designed with an enclosed Polyether-Class hose system. Polyether-class hoses are resistant to degradation, UV-resistant, durable, have good anti-aging properties and low-temperature-resistant properties. The DEWALT hose is also inside the tool until it transitions out of the tool at the guard handle. This encasing and shrouding protect the hose from snags and damage over time.

The Husqvarna water hose is made out of PVC Flex and tucks away nicely into a grooved channel, but the team felt that this hose is susceptible to snagging and damage.

The Milwaukee hose is exposed inside a small channel and secured with one clamp. Milwaukee uses PVC reinforced Nitrile Butadiene Rubber hose, designed for a long-life. The team felt that this hose could also be prone to snagging and damage. History and use have proven with gas model saws that have exposed hoses, over time they get hung up in metal and masonry – snag and rip off.

The DEWALT hose is visually smaller than the other two tools. One thing that we noticed is that DEWALT uses an internal stainless-steel spring inside the water hose as it travels up and over the saw to feed the other side of the disc. The spring results in a consistent hose radius.

Milwaukee’s hose was kinked in this location.  The Husqvarna and Milwaukee both use a larger water hose. The DEWALT hose nipple is stainless steel, Husqvarna is made out of brass and polymer and the and Milwaukee uses Nickel-Plated Aluminum. None of the saws suffered from water flow issues and the larger diameter Husqvarna, and Milwaukee hoses probably have a larger flow than the smaller DEWALT hose with the inserted spring.

Heavy Load Indicator

DEWALT and Milwaukee have a heavy load indicator.  This light tells the user that the tool is working hard, which will reduce battery life. Heavy load indicator light provides the user with real-time power and run-time feedback during demanding applications. If you want or need power it’s OK to keep pushing the tool “Go get it!” If you need additional run-time – back off.

Husqvarna has an indicator that will advise you when risking overloading or overheating the tool, and when the tool needs servicing. When seeing this indicator light both DEWALT and Milwaukee say backing off cutting pressure will increase run-time.

Milwaukee says pushing harder does NOT get you more with their tool. DEWALT says go get it and push if you need the power, but you’ll sacrifice on run-time.

We were able to stall all three saws by applying too much pressure. When pressing too hard, you can actually hear the saws struggle, indicating the need to back off slightly. This was something a user quickly gets used to and adjusts accordingly. On the DEWALT cut-off saw the light is either ON or OFF. Milwaukee says that the sweet spot is to get the light to flicker…. The perfect top-end of cut pressure/speed. They equate a flickering light to “Pushing to the edge of the cliff w/out overloading it.” [practice this to find sweet spot]

Milwaukee says when cutting rebar, you should “listen to the light,” and with concrete: pick a style and go!! [stay with it]

Drive System – Direct Drive vs Belt Driven

The folks at DEWALT say their shaft drive system is “Legit!” It’s a shaft drive system with a Lovejoy coupling. It is more efficient than a belt and helps minimize vibration. Because it is a shaft drive it will not slip and does not need regular maintenance unlike a belt that requires tensioning and replacement. DEWALT feels that their drive shaft is better than a belt-driven tool, resulting in no maintenance or slippage.

Husqvarna and Milwaukee both use a belt drive system and we noticed that the belt-driven saws result in slightly less cutting vibration. The Husqvarna and Milwaukee cut-off saws are smoother to run.

The Milwaukee vibrates at well under half of the vibration from the DEWALT. 
The Milwaukee has vibrations readings at 1.8 m/s² and the Husqvarna at 2.1 m/s².  All three of these tools vibrate 3 times less than an orbital sander, making them very smooth to operate and not imparting much vibration to the user. In contrast, an electrical demolition hammer is around 18-22 m/s^2.

All three saws have a similar design and size. The measurement from spindle to the rear handle set is the same as the popular gas models. On its simplest level, user experience [UX] is how you feel about every interaction you have with the tool in front of you, at the moment you’re using it. UX is a lot more than that; ranging from concept to research, engineering, prototyping, testing, and user testing, to list a few.

These tools were clearly designed to give users the same feel as a gas tool. Users are conditioned to the gas feel and these tools mimic that experience

Handles

All three tools featuring a front handle that can be held in three positions can be used to cut in both horizontal and vertical positions.

The DEWALT front rubberized handle looks a lot like the non-rubberized Husqvarna. It is comfortable, and the handle does an excellent job of providing comfort in overhead use applications.  The Dewalt front handle has a few indented places to rest a thumb when holding horizontal. We felt that these indexes were not great and would be hit or miss depending on the user.

The Husqvarna handle has more hand room than the other three, allowing for easy winter-gloved operation. The handle is has a smaller diameter, a nice gradual curve and is comfortable to use. The handles slight-slope to the side, was no doubt designed to user support hand, wrist and elbow comfort. It allows for many hand positions and does an excellent job of providing comfort in overhead use applications.

The Milwaukee cut off tool has a thick rubber rear handle, and a much a thinner, smooth plastic front handle. The handle design is straight across and allows more room for a gloved user. Comfort and securing the tool in the hands was the GOAL for these tool companies and they clearly approached their designs differently.

Base Shoe

DEWALT’s base shoe is wider than one would think it needs to be. The team felt that this shoe provided an excellent pivot point for plunge cutting. Husqvarna provides both a wide metal shoe plate with two rubber feet to keep the tool from sliding. The Milwaukee shoe plate is half the width.

The tools with the wider shoes result in the tool cutting straight and also helps with perpendicular plunge cutting.  The team felt that the wider DEWALT and Husqvarna bases provide more protection, better pivoting and provided better stability side to side.

Safety Switch

The DEWALT has a manual push-button on/off switch, once activated the tool trigger is live. The Husqvarna has an on / off keypad switch that will time-out with 1 minute of non-use. While this is outstanding as a safety feature, the team often picked up the tool to use it and were annoyed that they had to turn the saw back on repeatedly. The Husqvarna rear handle also has a “power trigger lockout safety switch”, similar to their chainsaws. Milwaukee uses a dual-trigger, which encompasses a small trigger safety- spring flap on the main trigger. The spring-loaded flap that needs to be depressed before activating the trigger.

Water Feed Valve

The DEWALT has a T-handle valve knob that is very easy to operate. The ease to operate also equated to valve slop – meaning that the knob had a lot of side-to-side play. Husqvarna separated their valve knob from the water nipple by placing t higher on the tool – a much easier location to reach and activate. The Milwaukee uses a  half t-style knob, we found it is stiff more secure and durable.

All three tools [dual-sided water delivery system] achieve OSHA Table 1 Compliant solution for dust management when cutting concrete and masonry materials.

Tool Head Style – Maneuverability

Left to Right [close] all three tools are small enough, and designed for a solid angle cut approach. With a fresh masonry blade attached, the DEWALT is capable of a 3-3/8” deep cut, the Husqvarna a 3″ cut and the Milwaukee a 3-1/2” deep cut.

9 Inch Cut Off Saw – Run-time Testing

WINNER – DEWALT

Which 9 Inch Cordless Cut Off Saw had the most run-time? We used several large 3″ thick slabs of granite scraps, fully charged batteries, and the same brand diamond blade for this test. After scribing lines on the granite, we had the same operators cut the slices of granite using the water cooling systems on the saws. We were careful not to push the saws too hard and monitored the load indicators to ensure that we did not use excessive pressure.

We continued to cut until the tool could no longer cut the granite. It was interesting to note that both DEWALT and Milwaukee [with the enclosed battery compartments] had thermal overloads activate before the batteries were exhausted. We allowed the hot batteries to cool and continued to cut until the battery registered no power. The Husqvarna battery is not enclosed in a compartment, so it did not have a thermal issue.

The DEWALT saw cut 3″ thick solid granite for a distance of  6’9-3/4″ on a single battery charge. The Milwaukee was able to cut 6’-4” and the Husqvarna 5’-7 3/4”.

Granite Cuts Per Watt-Hour

One interesting aspect of the run-time test came to light when the TBB Crew looked at the capacity of the batteries in the three cut-off saws. The DEWALT and Milwaukee saws have a 12.0 amp-hr battery. The Husqvarna has a 9.4 amp-hr battery. By using watt-hour (total battery pack energy) we level the field for both voltage and amp-hours.

Watt-Hours is calculated by multiplying the voltage (actual voltage, not the MAX that some companies advertise) by the battery pack Amp-Hours. This calculation allows us to compare the total energy available to do the work based on both the voltage and size of the battery pack (amp-hours).

The Husqvarna comes with a smaller amp-hour battery than the DEWALT or the Milwaukee (9.4 vs.12 amp-hr). However, the Husqvarna is a 36-volt battery. This means that the total watt-hr. for the Husqvarna is 338 vs. 216 watt-hr. for the other two saws. However, despite the size differential in watt-hr, the results look the same for the regular runtime test as for the normalized-runtime test. The DEWALT and Milwaukee saws are newer and the results of the normalized data show us that these two saws are more efficient than the Husqvarna.

9 Inch Cut-Off Saw –  Performance (Speed) Testing

WINNER  – MILWAUKEE

We performed a speed test in the 3″ granite to see which saw was capable of cutting the most granite in one minute. The operator pushed each saw to the point where the overload light came on, or rpm decreased, then backed off the pressure to operate in the tool’s performance “sweet spot.”   The test was timed and stopped after one minute of cutting.  The distance cut was measured at the bottom of the saw blade kerf. The Milwaukee cut slightly faster than the DEWALT and almost twice as fast as the Husqvarna.

What a great system to cut masonry and concrete with a tool that’s fully compatible with my BRAND  batteries ~ JEFF   [TBBCrew]

Steel Cut-Off Performance (Speed)

WINNER – DEWALT

The performance of the three saws were evaluated cutting steel. We put the saws through their paces by cutting five “ganged-together” set of #5 pieces of rebar. In addition, we cut through a piece of structural steel C-Channel. The TBB crew kept the saws spinning at, or near, they’re “sweet spots” for performance by modulating the pressure on the saws.

The DEWALT was the fastest cutting at 14.7 seconds followed Milwaukee 5-seconds after and third was the Husqvarna at 35.6 seconds.

• DEWALT was 14.7 sec
• Milwaukee was 19.2 – about 33% longer
• Husqvarna was 35.6 – 2.4 X  the DEWALT time

In both of these steel cutting tests, the DEWALT saw really outperformed the other two saws, as can be seen in the following two graphs.

In the 4” C-Channel steel cutting test, the DEWALT was the fastest saw, at 20 seconds, cutting almost twice as fast as the Milwaukee and four-times faster than the Husqvarna. The Milwaukee saw cut at 30.4 seconds and the Husqvarna at 80.5 seconds.

9 Inch Cut-Off Saw –  Ergonomics Evaluation

WINNER – HUSQVARNA

Ergonomics play a major role in all of our evaluations and 9-inch cordless cut off saw testing. Not only does a tool need to perform well, but it’s very important that tools are comfortable, which ultimately leads to more productivity and reduced risk of injury.

50% lighter than gas saws and with no gas headaches ~ ETHAN  [TBBCrew]

For the ergonomics evaluation, the team evaluated the following: grip, handle, blade guard, disc change, power switch, battery change, vibration, balance, and maneuverability. For each category, the team ranked them 1, 2 or 3, (1 being the best). Much of the ergonomics evaluation came from team members using the cut off saws. Each team member used each tool, cutting different materials to get a relative comparison of each tool.

The Husqvarna beat the DEWALT by one-point and the Milwaukee by six points. The Husqvarna excelled in almost every category but lost points due to its fixed disc guard, multiple switch operation,  and lack of onboard storage. Overall the team felt that the Husqvarna was the nicest, smoothest operating saw tested.

The saw starts with a squeeze of the trigger instead of repeated pulling on a cord and eliminates the need to mix gas and oil or maintain a gas engine, gotta love that! ~ STAN   [TBBCrew]

Both DEWALT and Milwaukee saws came out after the Husqvarna giving them time to improve their design. The DEWALT came in one point behind excelling on improvements to the grip, guard, and trigger switch.  The Milwaukee excelled in grip and was consistently number two in almost every category except blade change and maneuverability.

9 Inch Cut-Off Saw Best Price

WINNER – DEWALT

Pricing is a key part of the purchasing mix, and it’s crucial that you get it right in order to determine the Best 9-inch cordless cut off saw. For this Head-to-Head we looked at bare-tool pricing to eliminate discrepancies in the composition of the kits provided by different manufacturers. 

When you look at the bare tool pricing the DEWALT is lower than the competitors and a competitive kit price. Keep in mind that we tested the DEWALT kit with 12Ah batteries but at the time of publication the DEWALT kit comes with 9.0Ah batteries and the Milwaukee kit comes with 12Ah batteries which definitely adds value.

Below is a graph showing the pricing (at the time of publication) of each tool:

• DEWALT $549.00 
• Husqvarna $599.99
• Milwaukee $599.00

The DEWALT is $50.00 less than the Milwaukee and while a $50.00 difference is not a big spread, the bigger story may be purchasing this tool as an expansion to your current DEWALT or Milwaukee battery platform.

Less noise, less vibe, no maintenance and great for overhead work, that’s a win! ~ ROB [TBBCrew]

WINNER – DEWALT

As usual, the Head-to-Head competition was very close but at the end of the Day the Tool Box Buzz Crew must pick a winner and the DEWALT is our winner of Best 9 inch cordless cut-off saw.

The Best 9-Inch Cordless Cut-off saw is the DEWALT Flexvolt DCS690B. This saw looks feels and performs like a pro-grade tool. It was pretty obvious during our testing that the DEWALT was a powerful cutter, and the results showed that.  The DEWALT saw took first place in five categories, and second place in two categories for a total of 8-points. The first place categories were; features, runtime, [2] metal cutting speed tests and the bare tool price evaluation.

The Milwaukee came in second, with 12-points.  The Milwaukee took first place in the granite speed test, third place in ergonomics and second place in every other category. It is a powerful, fast, and solid performing saw. Following up in third place, with 16-points, was the Husqvarna, which took first place in ergonomics, second in price and third place in all other categories. The Husqvarna has been out a lot longer than the other two tools and has not benefited from a “Gen 2” upgrade. If they do – watch out!!

Final Thoughts  

So why would you want a 9 inch cordless cut-off saw?  The simplest answer is that these saws are an extremely versatile solution for cutting a large variety of materials, these tools harness cordless technology to deliver the power to cut metal and masonry materials without using gas like most traditional cut off saws.
