ABSTRACT:
A quick change right angle drill head incorporates mechanism rotating components within the drill head housing thereby resulting in a more compact package which facilitates use in space-limited locations. A single push button release enlarges a chuck opening to receive a cutting tool. An internally located compression spring becomes operative when reverse thrust forces are exerted against a cutting tool. The design of the present invention may be constructed to either lock the cutting tool into the drill head chuck or release it, upon exertion of the reverse thrust forces.
