Does the DCG410B come with a battery?

No. It is tool-only, so you need a DeWalt 20V MAX battery and charger separately. A 5.0Ah or larger pack suits heavy grinding better.

What size discs does it take?

It accepts 4-1/2 in and 5 in discs. The spindle is the standard DeWalt grinder fitting, so common grinding and cutting wheels fit.

How is it different from a corded grinder?

It trades corded power for portability. The 1,590 max watts out is strong for 20V, but continuous heavy work will still favor a corded unit.

What is the anti-rotation system?

It senses excessive rotational motion during a bind-up or kickback and shuts the tool down. It is part of DeWalt's PERFORM & PROTECT line.

Is $158.98 a good price?

It is the best new price found as of November 6, 2026, at the low end of its recent range. Only two stores list it new, so availability is limited.

Can it connect to a dust extractor?

Yes, through Wireless Tool Control, which turns a compatible DeWalt dust extractor on and off with the grinder. The extractor is sold separately.
