I have done a bunch of grinding concrete with a diamond grinding wheel as well as cutting steel beams with a cutoff wheel.
So far I am happy with the power and battery life. I can apply as much pressure as I normally would with a corded grinder and it doesn't slow down. The battery life will depend on how hard you work the tool (how hard you are pushing while grinding or cutting). I didn't actually time it but I think my 5.0 Ah battery was lasting for about 10 to 15 minutes of strait grinding or cutting.
I also find the tool feels comfortable to hold. The only thing negative I could say is the safety on the trigger is a bit fiddly to flip until you get used of it. This is typical of most grinders though.
I use my grinders a fair bit. So I figured I'd be the best and got myself a corded 11A Dewalt grinder. I confess, its amazing and can power its way thru anything but if you're using it for any period of time you'll have to put it down to give your arm a rest. Not this 20V XR grinder though. It's so lightweight that you can use it continuously, or at least until you run out of charged batteries (buy yourself some extra 5AH batteries now). As for power, its not bad. I actually prefer the lower rotation speed. It never stalls, just spins a bit slower than its wired siblings. Overall, I'd definitely buy another. I almost never take the corded out of the drawer anymore.
Nice addition to my 20v line of DEWALT tools. I love the fact that you can buy bare tools, if you have any other DEWALT tools, the chances are you have already got plenty of batteries and chargers, so why not save $$$ buying bare tools. The grinder itself isn't as fast and as powerful as the other corded grinder that I have, but it's fast enough to do the job and it's cordless!
Bought this for my father in law and he loved it. He was impressed by the brushless design as well as the quality. Was a great price and can't beat the battery design. Even with a nearly dead battery it had tons of power.
Its ok but i expected better from Dewalt. Once the battery gets about 1/2 full the grinder keeps cutting out. You have to get of the throttle and then start again and it works for about 30 seconds then stops again. Took it to a Dewalt shop in my town and was told go back to where I purchased it. All my other cordless tools are Dewalt, this is the only one that is giving me grief.
The product is great and works great, but for the price to arrive with out a battery was not worth ordering, I would rather have gone to Home Depot and buy the whole thing. Sad thing is when u look at the product u don’t expect them to send with out a battery. So in the end I spent to much not a good buy. How ever the tool works great and I am very happy with it. Just felt deceived is all. Not a good buy from this client. Go out and buy it complete
That eat battery like crazy. I had to grind rust on a metal post so I bough this grinder since I already had dewalt battery. I had used 4ah battery but they only last like 15 minutes top. I had to borrow a corded grinder to finish the job. If you have cutting or you need it cordless for roof job or something like that its perfect but if you need to use it intensively dont bought a battery grinder.
