⭐⭐⭐⭐⭐ 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!

Love it!
This was a great tool for my shed build! Very handy for cutting siding and soffit! I tried a Chinese knockoff the first time, but it lasted a couple days, returned it and bought this one. Finished the shed build and this is still going strong!

Extremely useful
I did a DIY kitchen backsplash tile installation recently. I borrowed a friend's wet saw and purchased this cut-off tool. I've found myself reaching for this more often than the wet-saw. This tool comes with a blade guard, but I find it difficult to see the blade path with the guard installed. Drawback is that cutting tile dry without a guard is extremely dusty. Face mask, glasses, hearing protection, etc. -- wear it all. I find it can make quicker cuts then a wet saw can and the results are just as clean. Spraying the tile with a water bottle before cutting helps somewhat with the dust as well; doing so doesn't seem to be "recommended", but seems to work just fine. The visibility issue with the guard installed is why I deducted a star from my review. The tool comes with various blades; I've used it for cutting metal Schluter tile trims and the tile itself. This is going to be a very useful tool for a variety of home improvement projects.

Great addition to the toolkit!
An absolute pleasure to work with, my new favorite go to when grinding anything small to medium.

It's a no brainer, unless...
An excellent mini angle grinder, definitely get it if you're already invested in the Dewalt 20v system. If not, I wouldn't call it a slam dunk even though the grinder is awesome. I have a feeling that with most other cordless tools Makita and Milwaukee have the lead.
