ABSTRACT:
A chuck for use with a manual or powered driver having a housing and a drive shaft rotatable with respect to the housing is provided. The chuck includes a generally cylindrical body having a forward section and a rearward section. The rearward section has an axial bore formed therein to mate with the drive shaft of the driver. A generally cylindrical sleeve is received over the body so that the sleeve is rotatable relative to the body. A gripping mechanism is actuatable to a closed position in which the gripping mechanism axially and rotationally retains a tool with respect to the body and to an open position in which the gripping mechanism does not so retain the tool. The gripping mechanism is in communication with the body and the sleeve so that relative rotation between the body and the sleeve actuates the gripping mechanism to one of the closed and open positions, depending on the direction of the relative rotation between the body and the sleeve. A locking mechanism is configured to selectively rotationally fix the body to the housing so that the relative rotation between the body and the housing is prevented while the sleeve is rotated relative to the body.
