Does it come with a battery and charger?

No. It is a bare tool; battery and charger are sold separately. Budget for a 20V MAX pack and charger if you do not already own them.

Is $119.99 a good price?

That is the best new price among 4 stores as of November 6, 2026. Bare-tool grinders in this class often sit near this level, so it is a fair price rather than a deep markdown.

What size discs does it take?

It takes 4-1/2 in. and 5 in. discs on an M14 spindle. Most 5 in. discs with a 7/8 in. arbor fit with the right flange.

How does it compare to the older brushed DEWALT grinder?

The XR brushless model runs cooler and longer per charge and adds the anti-rotation system. The brushed version is cheaper but heavier on batteries and lacks the kickback cutoff.

Is it too loud for indoor work?

It is rated 94 dB acoustic power, which is loud enough to need ear protection. Plan on hearing protection for any extended use.

Can it cut concrete or masonry?

Yes, with the right disc. Fit a diamond or masonry cutoff wheel and use the guard; the grinder is single-speed at 9,000 RPM.
