Designed for the professional tradesperson; The Milwaukee M12 Brushless Rotary Tool is optimized for power, precision, and productivity on the jobsite. Our new M12 Brushless Rotary Tool delivers unmatched performance with the fastest application speed and 30% higher RPM under load when paired with our M12 REDLITHIUM CP2.0 battery pack (not included). The combination of our brushless motor, REDLINK intelligence, and steel collet design provides longer life and class-leading durability. Our variable speed interface offers RPM adjustment from 27,500 to 5,000 with 12 speed settings to complete a wide range of cutting, grinding, sanding, and polishing applications. The compact size at 0.8 lbs and ergonomic contour grip provides greater comfort and control during usage, while the LED light illuminates the workpiece. Our M12 REDLITHIUM HIGH OUTPUT CP2.5 Battery Pack delivers 25% more power and runs 25% cooler vs our other M12 REDLITHIUM CP battery packs. This increased performance of the lithium-ion battery gives you the same power and runtime of an M12 REDLITHIUM XC battery in a lighter and more compact package. The 12-volt battery pack delivers fade-free power and runs substantially cooler through demanding applications, allowing you to push your cordless power tools throughout a wide range of applications.
