About this angle grinder
This is a cordless 4-1/2 inch angle grinder from Milwaukee's M18 line, powered by an 18-volt lithium-ion battery and fitted with a brushless motor, which the listing states. It runs at up to 9,000 RPM and comes as a kit with two XC 8.0 Ah batteries, so the batteries are included. The model also includes a 5-inch grinder. It may suit someone already invested in the M18 battery platform, since that is the power system this kit uses. Before buying, check that the 4-1/2 inch size fits the discs and tasks you have in mind, and confirm that the kit configuration, with its two batteries, matches what you need.
