Abstract

A chuck comprises a base 22 suitable for attachment to the driven shaft of the tool and a collar 20 threadably received by the base. Jaw means 44 are adapted to receive a work piece such as a drill bit, and rotation of the collar relative to the base operates to drive the jaw means into gripping engagement with the work piece. A truncated cone 50 is interposed between the collar and jaw means, and a thrust washer 40 is interposed between the base and jaw means. The structure permits the utilization of plastic for the collar and base. Other parts including the jaws, the force-applying cone, and the thrust washer are produced of hard metal, and these members are arranged so that the hard metal jaws and other hard parts do not damage the plastic. The thrust washer can be attached by means of an oppositely threaded fastener or other suitable means whereby the construction can be utilized in both forward and reverse operation of the tool. <IMAGE>
