Abstract A chuck for use with a power driver includes a generally cylindrical body, a plurality of jaws and a driving disk axially moveably disposed about the body in driving engagement with the jaws so that axial movement of the driving disk with respect to the body moves the jaws toward or away from the chuck body axis. The driving disk defines a threaded outer circumferential surface that engages a threaded inner circumferential surface of a generally cylindrical sleeve so that relative rotation between the sleeve and driving disk axially moves the driving disk with respect to the body. The driving disk defines a plurality of cylindrical slots extending at least partially radially therethrough.
