21000 RPM 12V 775 Motor

A powerful brushed motor commonly used in drill presses, small cutting tools, spindles and grinders. At 21000 rpm unloaded it is built for speed and raw power rather than fine control, with ball bearings and a metal body to handle the load and heat. Two things to plan for: it draws serious current under load, so size your supply and driver accordingly, and it needs airflow during sustained use. Not a motor to drive from a small hobby driver board. High speed and high power for tools and spindles; Ball bearings suit sustained high-speed running; Metal housing dissipates heat well; Widely used in drill presses and cutting tools
