  • YOU NEED THIS!!
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

  • Perfect!
We ordered the bundle and saved a lot. Amazon was where we found it at the best price. Husband said it fits comfortably in the hand and it’s easy to use. Cuts through nearly everything. Very happy with this product.

  • Awesome tool, until the trigger stops
Overall this has become one of the most versatile tools we use. And its used to cut everything -> bought it for tile, but now its more things like metal locks, window casings, large cast sewer pipes, random grinding, siding, and even down to trimming parts off my old foxbody. Its freaking awesome... until last month when the trigger sporadically works. You have to continually push the trigger and it comes to life for a fraction of a second with the wheel turning about an 1/8th of a turn. After pushing the trigger and moving the wheel a tiny bit about 100 or so times, it suddenly starts working. Repeat daily... its annoying as hell. Its not abused, prob dropped from 2 feet or less a few times in its life, and kept as clean as possible. I took it apart and cleaned it and it worked for about a week, now back to the same trigger issue. Such a good tool it deserves 5 stars. It gets so annoying it deserves 1 star. So 4 stars it is cause when it works, its just AWESOME. ... show more

  • Great Product
This is what a cutoff tool should be. The blade angle is much more comfortable than the pneumatic tool I had before. The easily removable guard is a great feature when cutting drywall, but should not be used with cutting metals. DeWALT does it again! I have replaced most of my tools with DeWALT 20v XL now. ... show more

  • Great tool.
Works fantastic. Saved me a lot of time trimming some Siding to install gable vents.

  • Powerful
I vacillated between this cut off tool and a traditional cordless angle grinder. After thinking back over my prior projects I determined that a cut off tool was more practical for small cutting jobs. I have an air cut off tool but it consumes compressed air quickly and bogs down. I use a 5 ah battery on this tool because it will drain lower capacity batteries quickly. I use it to cut rebar in half and cut off seized bolts, protruding nails and screws, etc. It's very powerful and has a consistent speed while cutting. Easy cutting disc changes. It has an adjustable shoe with a clear plastic guard so you can start your cut in the same kerf. I don't use this tool daily, but one of two uses will convince you that it belongs in your arsenal. Very happy with another DeWalt purchase. ... show more
