ABSTRACT:
A quick change tool holder is disclosed which allows tools to be changed while a collet holding the tools is rotating. The quick change tool holder comprises a stationary housing, a quill rotatably supported within the housing, a collet rotatingly engaged by the quill, the collet adapted to releasingly engage a tool. A rotatable sleeve threadingly engages the housing, and rotation of the sleeve in a first direction releases a tool held in the collet for removal of the tool while the collet is rotating. Rotation of the sleeve in a second direction engages the shank of a tool that has been placed within the collet for rotation therewith. The removal or insertion of a tool can be made while the collet is rotating.
