Abstract
A surgical drill assembly is provided having a clutch mechanism that requires a sufficient axial load on cutting surfaces of the drill to enable rotation of the drill. Rotation of the drill ceases almost immediately upon the axial load falling below the predetermined axial load threshold. In one embodiment the drill assembly is disposable, and is virtually impossible to disassemble and reassemble to an operative form. In another embodiment the drill assembly is reusable. The reusable embodiment includes a drill body that enables quick and easy attachment and detachment of a drill head. The reusable drill body is of a unitary construction that can be sterilized and reused without any disassembly.
