Abstract: A true length collet chuck assembly is adapted to receive and actuate a quick change, segmented collet having a flange extending radially outwardly from the outer surface of the collet adjacent a rear face of the collet. The collet chuck assembly comprises a chuck body having a longitudinally extending bore defined by an inwardly facing, cylindrical surface on the chuck body. The inwardly facing, cylindrical surface on the chuck body defines a circumferential groove for receiving the radially outwardly extending flange on the collet to thereby restrain the collet against axial movement relative to the chuck body. A collet closing sleeve, disposed within the chuck body and axially displaceable relative thereto, has an outwardly flaring interior surface adapted to engage an outwardly flaring surface on the collet.
