ABSTRACT:
A tool holder device for drill bits, screw tip bits and like tools permits rapid exchange of the tools. A holder body of the device defines a tool receiving opening in one end thereof for receiving the shank of a tool therein. A spring clip is secured at one end thereof to the holder body and is movable between an operative position wherein the other end of the clip engages and retains a tool received in the opening in the holder body and an inoperative position wherein the clip is out of engagement with that tool so that the tool can be replaced. An axially movable control pin is received in a transverse bore through the holder body and is of a length longer than that bore. A control lever secured to the holder body is movable between a first position wherein the control lever engages one end of the pin and causes movement of the pin to a position wherein the other end of the pin causes positioning of the clip in the inoperative position thereof, and a second position wherein the control lever is out of engagement with the pin and thereby permits movement of the retaining clip to the operative positive thereof.
