Overview

The Air YDG21061 is an air powered die grinder that spins at 20000 RPM with a 0.3 horsepower rating. It weighs 0.6 kilograms and requires a compressed air source to run.

Pneumatic die grinders like this one run off shop compressed air rather than a battery or cord, which keeps the tool itself light at just 0.6 kilograms while the compressor supplies the power. The 20000 RPM speed is typical of small die grinders used for deburring, polishing and detail grinding rather than heavy stock removal.
