Abstract
A chuck and tool assembly in which the tool is formed with a continuous axially extending flat surface along its elongated shank and has axially spaced depressions which narrow away from that surface. The holder body has an axial bore receiving the shank and a pair of screws spaced apart axially so that when one of the screws engages in one of the depressions, the other screw bears upon a flat surface between two depressions to lock the tool in the holder body.
