Abstract

A tool driver includes a housing and a rotatable drive shaft extending therefrom. A chuck for holding the tool includes a generally cylindrical body having a nose section and a tail section. Each of a plurality of jaws is slidably positioned in one of a plurality of angularly disposed passageways in the body. Each jaw has a jaw face and threads formed thereon. A nut is in operative communication with the drive shall so that the drive shaft rotationally drives the nut. The nut threads engage the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A sleeve is selectively actuatable to a first axial position and a second axial position. The sleeve defines a first slot that receives a detent mechanism in the first axial position and a second slot that receives the detent mechanism in the second axial position.
