ABSTRACT:
A hand-held device for use in drilling or the like includes a tool holder mounted on a rotating spindle. The tool holder is secured to the spindle so that there is no relative rotation between them. The tool holder has a support ring for securing locking elements in locking engagement within recesses in the spindle. A blocking element secures the support ring against rotation so that the locking engagement is maintained. By releasing the blocking element, the support ring can be rotated releasing the locking elements so that the tool holder can be removed from the spindle.
