Powerful, Compact, and Easy to Handle
I’m very happy with this DEWALT angle grinder. I really like that it’s cordless because it makes the job much more convenient without having to deal with a power cord. It has plenty of power for cutting, grinding, and working with different types of metal. I also like that it’s compact and easy to handle, especially when working in tight spaces. The handle feels comfortable in my hand, and the safety features give me more confidence while using it. Overall, I think it’s a great-quality, practical, and durable tool. It’s a great choice for both home projects and more demanding jobs.

Missing Manufacturer packaging.
I’d give it 5 stars but I deducted 1 star for the missing manufactures packaging and photo copied instructions. It looked unused but was just tossed into bubble wrap and put in a large amazon box. I’m sure it got banged around when being moved. And it took over 2 1/2 weeks to get it for Amazon Prime. I will update the review after I’ve used it. I always buy Dewalt since all my batteries are dewalt!

Really comfortable grinder with slide switch.
I got this to add to my suite of 20v tools. My kit came with the more typical trigger switch but I don't like that feature, especially for longer sessions of grinding (just my preference). This grinder is powerful, lightweight and the ergonomics are great. The motor is powerful and efficient, and did a relatively long grinding session, cutting rebar, grinding welding beads flat (so people don't see what a crappy welder I am!). And it has a nice brake, that came in handy when one of the rebars pinched the wheel, and it basically "slipped" as the brake should, preventing an unpleasant kickback, since this is a powerful tool. Also like the slide switch design, eliminating the need for a separate lock-out switch you have to deal with. It has a shaft lock button on top of the grinder, allowing easy on/off installation of the wheels, and not sure if they made it this way but I don't need tools to remove/install wheels. Overall great 20V Mas XR grinder, and love the Dewalt 20v system, overall.
