Abstract
A chuck includes a generally cylindrical body having a nose section and a tail section. The tail section is adapted to rotate with the drive shaft, and the nose section has an axial bore formed therein. A driver is axially movably disposed about the body. A generally cylindrical sleeve is rotatably mounted about the body. A grip is mounted in the body in communication with the axial bore and in operative communication with the driver. The driver is in communication with the sleeve and the body so that, in a first state of the chuck, rotation of the sleeve with respect to the body in a closing direction moves the grip toward the axis of the axial bore and so that, in a second state of the chuck, the driver is axially reciprocal with respect to the sleeve and the body.
