ABSTRACT:
A tool clamping device comprises an axial sleeve having a forwardly tapering internal surface. A radially compressible ring is disposed on the internal surface. An axially compressible spring opposes axial movement of the ring while permitting axial rearward movement of the sleeve whereby the tapering surface of the sleeve compresses the ring radially inwardly into coupling engagement with a groove formed in a tool holder.
