Not impressed.
Was waiting for this item to arrive. Only to find out it was cancelled a day after I purchased it. Ended up costing me more to repurchase it thanit was to go through another retailer. Not happy as I was not given a reason as to why the item was cancelled.

Missing one important feature!
I have used mine several times but I think dewalt missed the mark or rather missed a really big marked. If they would have made this thing variable speed this tool would be used by concrete and stone polishers everywhere also if they made a sealed unit for to be water safe would be huge

Bought this for work, i tested on some 3/4” plate and was impressed with the power even when pushing hard to see how it handled. Ive only used 5” cutting disc and flapper wheels but they worked flawlessly, only drawback was 6.0ah battery did not last as long as i hoped for but than again i was working it really hard for constant cutting. This thing is more meant for cutting stuff that packing cords etc is a pain or just need to make a quick cut. Although i would like to try the 9.0ah battery and see if theres better runtime. A def must have for anyone in millwrighting or automotive or similar!

This is my first dewalt cordless grinder. It comes to work with me, even though i have shop provided power tools.
I have used other brands and found them to be lacking in power, run time and performance. This Flexvolt grinder is a different machine. It will zip through fiberglass, 5/8'' U-bolts, power through sanding and other prep/demo tasks. i havent been able to bog it down with a 4.5 abrasive disk or anything of the sort.
Once you look past the price, you realize that you've got the best cordless grinder, period, a battery system that works with your existing 20v tools, and a fast charger.

Best cordless grinder
This feels like a 7" corded grinder. I like the weight displacement with the battery, it makes it one handed operational. Try I swing one hand with a 7" rat tail grinder. Some says it's heavy, maybe compared to little 4 1/2" grinders. This is no little grinder. It's power destroys the others.

I bought this to use at the junkyard as a cutoff wheel more than anything else. However while its perfect for that use. Its also become a tool that I use when doing heavy fab work. I have both the 20v Max grinder and a corded dewalt grinder. But this is the one I use most often. I find it has almost as much power as the corded grinder but the kick back brake has saved me a couple of trips to the hospital on a few occasions. It definitely hogs off material far quicker than the 20v grinder does. Its also a smoother running grinder than the 20v. I just love it! Plus the fact that as a diesel mechanic I'm able to get these tools from the Mac Tools distributor (tool truck just makes it that much better because the wife doesn't have to know how much they cost...! I will definitely be getting more FlexVolt tools in the very near future.
