About this angle grinder
This cordless angle grinder runs on an 18V lithium-ion battery and uses a brushless motor, with a stated top speed of 9,000 RPM. It takes 4-1/2 inch discs and comes with two batteries, so you can keep one charged while working with the other. It is part of the M18 battery platform. This grinder suits anyone already working with M18 batteries or looking to build a cordless setup around that system. Check that you need the 4-1/2 inch size, and note that this kit is for the grinder with its two batteries as listed, with no other configurations offered for this model.
