ABSTRACT:
A collet chuck assembly is provided for accommodating workpieces of unusual shape and non-standardized sizes, as well as standard sizes. The assembly includes an insert configured to be firmly received into and held by standard sized collets. The insert has circumferentially spaced longitudinally extending radial slots forming jaws arranged to coact with a conventional collet for receiving and holding a workpiece. Preferably, at least the forwardmost portion of the insert body is comprised of a soft metal which may be easily machined, after the insert is received in the collet, for accommodating unconventionally shaped and sized workpieces.
