Abstract
A tool for forming a stepped blind hole in bone for receipt of a fracture reducing and stabilizing surgical implant. The tool comprises a small diameter drill portion axially adjustable with respect to a larger diameter reamer portion. A conical portion includes cutting surfaces to chamfer the entrance of the hole and also includes non-cutting portions which serve to limit penetration of the tool into the bone. The tool is cannulated to allow its use in conjunction with a previously installed Kirschner guide wire.
