These die grinders are powered by Milwaukee batteries of a compatible series and matching voltage

The batteries can also power other Milwaukee tools. Tools using lower-voltage batteries are generally lighter and more compact but less powerful than tools using higher-voltage batteries

Tools using lower-capacity (Ah) batteries are less bulky but store less power than tools using higher-capacity batteries.

APPLICATIONS: Ideal for cutting rebar or pipe, grove stone or concrete or grind metal and masonry

POWER: Power through tough applications with a no-load speed of 9,000 RPM

MODES: Auto-mode option automatically adjusts the RPM down when the tool is not under load, resulting in a decrease in noise and vibration, while also sparing the life of the battery for optimum performance
