Abstract
A collet clamping nosepiece for a power feed drill is described which includes at least one clamping piston located along a centerline of the nosepiece, an expansion mandrel comprising a frusto-conical exterior surface, and an expandable collet. The expandable collet is configured to substantially surround the expansion mandrel and operatively connect to the at least one clamping piston. Operation of the at least one clamping piston causes the mandrel to move along the exterior surface of the expansion mandrel for engagement and disengagement of the collet with a bore configured for insertion of the collet.
