ABSTRACT:
Manually operable tool means includes a frame formed at one side with an apertured work piece holder, and at an opposite side with an internally threaded shaft housing in which is adjustably mounted tool supporting means and a tool element. The tool element in the form of a drill, for example, while engaged with a work piece supported in the holder is turned by means of a spring loaded handle. The tool supporting means consists in a tubular adapter sleeve which is in threaded engagement with the internally threaded housing, and which is provided with a pressure-transmitting collar against which the handle engages. The tool shaft is rotatably mounted in the adapter sleeve and has the tool element detachably secured at one end. A range of pressures may be exerted through the tool element while cutting by varying the angular position of the handle against the collar as the tool is manually turned.
