Abstract
A drill assembly includes a handle carrying a mount for a pneumatic drill motor, and an elongated tubular support enclosing an extended motor shaft which carries a drill bit chuck projecting from the end of that support. The drill assembly coacts with a drill guide assembly including an elongated tubular guide for receiving the tubular support in sliding relation, and having a rotary bearing at its lower end for rotationally supporting the drill bit. The lower end face is concave to enable seating on the prosthesis tip to be drilled. The drill guide assembly includes an offset handle and a stop clamp and depth gauge for coaction with the drill assembly handle to control the depth of drilling.
