ABSTRACT:
A collet chuck with a tubular outer body has an internal tubular collet with cam surfaces at its outer end divided into sections by axial slots. Three or more centering screws are threaded through the outer body and pass through the slots in the collet to engage in radial holes in a cylindrical ring that is internally threaded. A cup shaped cylinder is externally threaded and adjustably threaded through the ring as a first and external stop within the collet. The ring has a chordal slot with a set screw extending through one side to defom the threads and lock the ring relative to the stop. A small central rod is threaded through the bottom of the first stop as an adjustable inner stop and is provided with a lock nut bearing against the bottom of the cup.
