ABSTRACT:
A chuck with a generally cylindrical body having a tail section configured to receive a drive shaft of a driver and a nose section having an axial bore formed therein. A plurality of jaws is movably disposed with respect to the body. A nut is rotatably mounted about the body and operatively engages the jaws. A sleeve is non-rotatably coupled to the nut. A shield cap is rotatably secured about the nose section of the body. The chuck also includes a first ring and a second ring that rotates relative to the nut over a limited arc. One of the first ring and the second ring defines a ratchet and the other defines at least one deflectable tab that is biased toward and engages the ratchet.
