ABSTRACT:
A hand-held power screwdriver or like tool includes a spindle which is adapted to receive and retain tool bits for rotation thereon. A collet ring is retained with a recess on the housing for slidable movement along the spindle axis. The collet functions as a selectable spindle locking device whereby the tool may be operated as a manual screwdriver or the like by selectively positioning the collet to rigidly lock the spindle in fixed relationship to the tool housing.
