Overview

A 21 volt cordless angle grinder from SEESII running at 12000 RPM, sized at 16 by 7.5 by 5 inches for handheld cutting and grinding work away from a power outlet.

12000 RPM is a typical spindle speed for handheld angle grinders used on cutting and grinding discs, and the 21 volt battery platform gives it cordless portability over corded shop grinders. Disc size, arbor size and included accessories are not listed, so match those against your existing discs before buying.
