    • YOU NEED THIS!!
Review Image by Greg Wiedeman Greg Wiedeman
Wow, this small cutoff tool is incredibly impressive! I used it to cut my entire patio, and the results went beyond my expectations. The powerful performance it provides makes it ideal for cutting stone and masonry easily. Its lightweight design and simple handling have quickly made it my favorite tool for working with stone. If you're searching for a dependable, efficient tool that gets the job done effortlessly, this is the one you need! The cordless feature is also a bonus. The tools cut accurately, and the speed is fantastic. The battery lasted through cutting 10 stones before needing a second, but they charge so fast—just keep a couple handy. ... show more

    • ⭐⭐⭐⭐⭐ Pocket Rocket of Power! The Most Versatile Tool I Own
The DeWalt 20V MAX XR Cut-Off Tool is not just a niche specialty tool; it is a compact powerhouse that has become my most used and favorite grab-and-go device in the truck. If you are looking for a small tool that can tackle huge jobs with minimal fuss, this is it. Unmatched Versatility in a Tiny Package What makes this tool truly shine is its ability to handle virtually any material you throw at it. I’ve been blown away by its capability and have used it on countless projects: Wood: Quickly trimming down fence pickets or cutting away damaged wood sections. Tile/Concrete: Cutting intricate curves in floor tile or making shallow, precise cuts through concrete patches and mortar. Metal: Slicing through bolts, rebar, or light gauge metal sheeting. Changing blades is fast, and the small size allows you to get into places where a full-size angle grinder would never fit. Power, Portability, and Endurance Despite its small form factor, the brushless motor and XR technology deliver plenty of torque. It chews through material much faster than you’d expect. The fact that it's so compact means I rarely bother dragging out bigger, corded tools anymore. It’s always charged, always in the truck, and always ready for that unexpected cut. The convenience factor of this tool is what truly sets it apart. If you are a professional or a serious DIYer who needs reliable cutting power across multiple materials, this is a 100% essential purchase. It’s a small tool that performs like a giant. Highly recommend! ... show more

    • Great tool
This is a great little machine Especially if you use a multi purpose blade on it. It puts the milwaukee 12 volts on its pocket Any day of the week. I have both of them. Just saying before you start b******* over there.

    • Very quick work of car exhaust cutting.
I have owned DEWALT tools for about 10 years. I have always found them to be reliable and long lasting. I needed this cutoff saw to cut an exhaust pipe that was hanging under a car in a junk yard. Too far away to string a power cord, and too small of a space for anything I owned to do the job. The saw cuts very quickly and isn't overly rough on the cutting blades. My Dremel tools (corded) go through cutting discs way too fast. So no problem hear with the DEWALT. The saw also did not draw much on the battery. I had the saw on for probably 15 minutes total. I do have one issue with the saw: The speed on the blade rotation is really fast. I don't know if it has to be that way, but I would prefer a variable speed or maybe a 2 or 3 speed. Some jobs require a more gentle touch and a slower RPM option would make it better. I did not have an extra hand to video my work, but perhaps on the next project I can make an addition to this review. ... show more

    • Buy it. You won't be sorry.
This little cutter is awesome 0 kickback. It shuts down before it will twist and snap the cutting disc. You just gotta let the tool do the work. One hand cuts are common and easy. Compared to a 4 inch grinder with no blade guard. It's balance is spot on even with a 6 ah battery. I doubt I'll ever use a 4 inch or 6 inch cut off wheel again. It blasted through a 1/4 steel plate with very little effort. Almost no vibration at the start and throughout the cut. Feels very safe. The DeWalt all metals disk it came with didn't do that great on 1/4 aluminum. It started plugging up the disk. Which is common w cutting aluminum. This thing would be perfect for using in the field. Cutting tops of posts.. whatever. Totally worth it. After using it once. I would pay double what I paid. It's that good.👍 ... show more

    • Another Good Dewalt Tool To Have
Just purchased and like the size and feel for my small jobs. Very happy with all of my Dewalt products and expect this one to perform well. Have several small uses already planned.
