Lots of power.
I’ve had this for 6 months or so and I can tell you it’s way more powerful than the Hilti cordless grinder I use at work. I have used it for cutting, grinding, and sanding and I have never stalled it out like others. I would highly recommend this to anyone who needs a cordless grinder.

Works great with lots of power. The fact it can do both 6in - 4in discs is handy. Runtime is good for my needs.

We got of these at work and it slices through thick welds easy. Be careful the sparks were noticeably hotter than other grinders.

The workhorse of my work day, makes life easy.
Working in an industrial environment everyday with these tools manufacturing heavy oil field equipment. Replaced corded tools with the DeWalt tools and have removed the limitations of power cords.

This grinder is either in my hands or next to me ready to work. Powerful and able to handle any material, I get through much more in a day than dragging cords around the large material we work with. The safety brake stops the wheel quick so you can set it down and get back to work.

The battery life under full grinding may seem small until you consider how much work the tool is doing. Using the grinder throughout the day I have never drained all four of my batteries. Quality is there, been using this grinder hard for over five months and still running like it was out of the box.

I've had the grinder for about 3 months now, couldnt be happier with it. Lots of run time with the 60v battery and power. I'll never go back to a corded one

Great usability
The guard is easily adjustable and the tool is comfortable to use. Very happy with the performance and battery life. I have used for both heavy steel and sheet metal and it performed well for both.

Had this for a little while now used it quite a bit only issue I’ve had is that it eats through the 2ah batteries pretty quickly. A solid well built tool.

As others have experienced, this grinder packs a lot of power, even though its battery powered. im now a believer that battery powered tools are on par with the corded versions. Fits in your hands well and has a nice e-brake. Indexible guard is a great design.

Does the battery die fast?
A shopper on Sep 22, 2017
BEST ANSWER: The answer depends on the capacity of the battery and the application. For the best results, we suggest using a 5 - 6 amp hour battery.
can it cut wood?
classicj on Apr 30, 2017
BEST ANSWER: Grinders are traditionally used for metal and masonry applications, but with the right blade, you could use it for woodworking applications. We would recommend using a multi-tool or something similar to a Rockwell RK3441K
