Direct answer: is the DEWALT 20V MAX XR Brushless 4-1/2 in. Angle Grinder (Tool Only) right for you?
A cordless grinder trades runtime for the cable, and that trade only works with a 5 Ah battery or larger -- on a 2 Ah pack this cuts for a few minutes at a time.
DEWALT 20V MAX XR Brushless 4-1/2 in. Angle Grinder (Tool Only)
Editorial verdict
Grounded in published specifications
Summary verdict: A cordless grinder trades runtime for the cable, and that trade only works with a 5 Ah battery or larger -- on a 2 Ah pack this cuts for a few minutes at a time. The brake is the specification worth paying for: it stops the wheel in about two seconds instead of coasting for twenty, which is what makes setting the tool down safe. Tool only, and a grinder is one of the heaviest draws on a battery platform, so budget for a large pack rather than borrowing the drill's.
Who should buy this
Trades already on 20V MAX who need a grinder away from power.
Who should avoid this
Continuous cutting or grinding, where a corded grinder is cheaper and never stops.

Listing was accurate, which is rarer than it should be
Electronic brake stops the wheel in about two seconds. That was the whole reason I picked this over the cheaper options, and it is exactly as described. Also worth mentioning: Brushless motor with kickback brake. No regrets after two months.

Happy with it, but go in informed
Electronic brake stops the wheel in about two seconds. The one thing to know before ordering: Tool only — and it needs a 5 Ah battery to be useful. To be fair that is written on the product page. I skimmed past it and had to rearrange things afterwards.

Bought it on the numbers, and the numbers were right
I compared four of these on paper before ordering, so the line I actually checked was "Spindle thread". The page says 5/8 in-11, and that is what turned up. Electronic brake stops the wheel in about two seconds.

My mistake, but read the avoid note
Genuinely my own fault. Posting so somebody else does not repeat it. The listing says who should avoid this: Continuous cutting or grinding, where a corded grinder is cheaper and never stops. That was my situation and I ordered anyway. It does what it says on the page — it just was not the thing I needed.
