Milwaukee M12 Cordless Lithium-Ion Rotary Tool (Bare Tool).

The M12™ Cordless Lithium-Ion Rotary Tool (Bare Tool) operates at between 5,000 and 32,000 rpm to power through any task. This multitool runs on the high-performance, long-running M12 battery system. The lithium-ion rotary tool's collet accepts all 1/32-inch to 1/8-inch-shank accessories, to give you the versatility you need to sand, polish, grind, cut and perform many other operations on each project. At just 9.5 inches long, this tool fits wherever you need it so you can take care of minute details. Since this M12 rotary tool weighs just 1.3 pounds, it's easy to operate even for long stretches of time. Grinder-style exhaust ports keep debris from getting into the tool to protect the inner workings. A protected front bearing defends against impacts and drops to ensure a long tool life.
