⭐⭐⭐⭐⭐ 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.

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.

⭐⭐⭐⭐⭐ Small but Mighty Cut-Off Tool
The DEWALT DCS438B 20V MAX* XR Brushless 3-Inch Compact Cut-Off Tool is small but mighty, with so many uses around the shop, garage, and jobsite. Its compact size makes it easy to handle and maneuver in tight spaces, while still delivering plenty of power for cutting metal, tile, plastic, and more. The battery is easy to charge, and it seems to last forever between charges. I also appreciate that it’s cordless, so there’s no cord getting in the way while working. This is a very convenient and versatile tool that has quickly become one of my go-to tools for a variety of projects.

Amazing little thing!
I am a diver and needed to cut many tiles both internal and external, and also for small wood pieces. I was deciding between the compact DeWalt saw and this cut off tool, in the end chose this, based on: 1. Size - this thing is super compact and light, as a result, it is very easy to control with 1 hand. 2. Saw blade - the DeWalt compact saw is also amazing, but for wood cutting mainly and the blades are limited. 3. The power - don't be fooled by the size, this little thing throws a punch and cut through tough porcelain 3cm external tiles like butter. Paired with 5Ah battery, it gets the job done. However due to the size and design, one could argue an angled grinder might be more versatile as one cutting tool to rule them all. I don't disagree. But with my usage which focused on cutting straight line with ease, this I think will be better than an angled grinder. So, happy days. Cannot wait for my next project.
