Abstract
An integrated and collet and chuck device includes a body member configured to be non-movably fixed to a drive spindle of a driving tool. An outer sleeve member is disposed about a portion of the body member and is rotatable relative to the body member. The sleeve member comprises a front end defining a collet receiving chamber for carrying a conventional collet. A nut is configured with the sleeve member so as to be rotatable therewith relative to the body member. A screw member is disposed rotatably concentric within the nut. The screw and nut are threadedly engaged so that rotation of the nut drives the screw member in the longitudinal direction. The screw member has a collet engaging surface which presses the collet within the frusto-conical inner diameter surface of the sleeve thereby causing the collet to collapse and grip upon the shank of a tool carried therein.
