ABSTRACT:
A quick release chuck device includes a body member and a device for attaching the body member to a drive spindle. A chamber in the body member receives a conventional collet. Thread grooves are defined on the outer circumferential surface of the body member. An operating sleeve is rotatably mounted on the body member and includes thread grooves defined on the inner circumferential surface. Rolling bodies are received in the thread grooves of the body member and sleeve member wherein the sleeve member is axially movable relative to the body member upon rotation of the sleeve member through engagement of the rolling bodies in the thread grooves. The sleeve member imparts a force to the collet in the chamber causing the collet to grip upon a tool shank carried therein.
