My Rating 8/10
For a battery operated tool this Dewalt 20v grinder has plenty of power comparable to a corded model. I like the two safety features, the anti-kickback and the brakes but I wish they kick in faster instead of taking 1.5 seconds to full stop. This one needs a stronger battery a 5 or 6 AH battery will give you all the power you need. If you use a 2 AH battery it wont last long might feel under powered.
Overall Solid built, Quick stop, Cuts and Grinds as it’s built for. Just get some high amp batteries for longer use.
