ABSTRACT:
A clamping device for a power tool that axially secures a disc shaped tool to its spindle. The clamping device securely attaches a grinding wheel or circular saw to a power tool by a contact surface on the clamping device and a screw-on flange that directly contacts the tool. The clamping device counteracts inertial forces that loosen the tool upon sudden deceleration.
