Questions & Answers


can I use this to cut concrete?

Asked by Anthony May 15, 2021

Hello Anthony, While technically this tool could cut concrete, it’s not at all practical based on engine & blade size. However, where this tool shines in my experience, is cutting small tile, grinding out grout & sheet metal/tin. It will cut 1/8” steel plate but, again not practical. Anthony, this will also cut copper tubing & PVC’s quite well (deburring of course is still needed). Good luck!

Can it be used to score retainig wall bricks, so i can make small custom size pieces?

Asked by PartimeToolguy May 12, 2021

yes it will score it nicely, it is a very easy tool to user

When attached, should the shoe guard allow for a little wiggle/play, or should it be firmly attac...

Asked by TWI April 25, 2021

Hello TWI! If I understand your question correctly, the guard should be firm in place with no wiggle. Good luck sir!

is this ideal for cutting drywall or am I better off just using a utility knife?

Asked by thatguy April 25, 2021

no not good for Drywall to much dust better to use a knife or a small sawzall

How much power does this tool have? Does it have at least the same amount of power as the M12 Fu...

Asked by TWI April 11, 2021

yes better use the big battery the saw uses a lot of power

IF U DONT KNOW, DONT ANSWER! Does anybody know of a cut off blade that is designed to cut wood? I...

Asked by Craig March 22, 2021

I can pretty confidently say that there isn't one. I have looked far and wide, name brand, off brand, through a plethora of websites and blades, and haven't been able to find one. Don't shoot the messenger.

Can I cut wood with this tool?

Asked by Mike March 22, 2021



Asked by JC February 26, 2021

Yes. I use it to cut aluminium shower doors. It cuts slow though.

Can I use this to cut laminate flooring?

Asked by PrimeRealty February 15, 2021

you could if you do not have much to cut. But making a good square cut can be hard

Can it be used for buffing?

This little thing is amazing!
I've used this tool on 4 different projects in the first week. Changing the blades is a snap and takes about 2 minutes. The power is surprising and it blew through stainless steel and then 50 year old plumbing pipe that ate a metal Sawzall blade in seconds (not cast iron pipe either). I was able to finish cut terra cotta pipe and finished fiberglass... The uses are endless. I'd buy this again without question and highly recommend it!

I love milwaukee tools!
This tool works great. (fyi for anyone buying: the auto stop protect feature will wear in overtime so dont be alarmed!) its to protect the fuel motor ;) nice cutting tool for basic cuts, i figured the compact'ness would help me get in to those tighter areas but it would be nice if the cutting blade "stuck out" a little more and if the motor portion was shorter, if possible. I continue finding the tool/motor bumping into other surfaces and not being able to get it in there, then switching to the either angle grinder, die grinder, or the vibrating multitool. Works great for straight cuts on top of metal or even wood if u got the blade, love it, just wish it were designed to get into tighter areas like you'd think
by jacobi
M12 3” circular saw
I was debating on this little guy or the 6-1/2 saw I figured that I would get this one and I’m impressed with how small it is and powerful Milwaukee is definitely top of the line with there tools I’ll never buy anything else they have seriously done a great job with all the M12 tools small and tough as heck love it buy it
by Scotts752
Perfect for any cutouts on any material.
This tool is the perfect multi functional cutting tool. Compact size. The forward and reverse options to make the best possible cuts without fear of the blade jumping the edge and damaging finished surfaces. Haven’t quite perfected installing and removing the guard. May be that I’m doing something wrong.
by RED 371
great tool
I do a lot of small projects that use various sizes of metal. in the past i would use a scroll saw with a metal cutting blade or put a metal cutting blade on my hand saw. this tool handles all those situations. it’s light, easy to handle with one hand, and the forward/reverse switch helps with cutting direction and directing cuttings away from you. used it to cut through 4x4x1/4 angle iron. went right through, just take your time and let the wheel cut. the add on blade wheel guard has a vacuum port and flat guide so it’s like using a hand saw.
by 99jeep
Worth every penny!
Bought this to cut wire shelving in a pantry that I just built, needless to say this cut off saw handled the cutting like a charm, smooth and quick. 48 ft of wire shelving cut precisely and in a short manner of time. It was great that I could cut forward and reverse to keep the sparks away from my face and body. What a great tool!
by petienne
Ideal solution for a single handed cutting tool
Weight and portability is very nice. Bought for doing high end aluminium soffit and siding. Could use an 18v version, as power is a little lacking unless you slap a 6AH battery on. Directional blade control is a game changer, as there are many different applications. Love the dust shoe, great for keeping the metal fragments contained during a cut. Only things I would change is the range in which the guard can turn, and the light should illuminate the material in front of the dust shoe, instead of from underneath
by Hawn Aldo
Great when you need a compact tool
Did a great job for what I needed (cutting already installed floor tile in a confined space). Easy to change discs. It does it bound up easily so you have to take it slow. The cover is nice to control dust but the plastic window is difficult to see through.
by Bjdraw
Good compact tool ideal for cutting mc,pipe and metal but battery would last only for 30 minutes or so. pretty ideal for small tight spaces and definetely will keep it.
Immediately let down by the lack of torque
I have a lot of M18 and M12 tools for a variety of tasks. I bought this tool specifically because I had a job that required cutting a lots of 1/8" aluminum stock into 1 foot sections. The stock was only 1-1/2 inches wide. The motor would constantly overload and stop. Very disappointed in its performance
