PCT No. PCT/EP94/02009 Sec. 371 Date Nov. 6, 1996 Sec. 102(e) Date Nov. 6, 1996 PCT Filed Jun. 20, 1994 PCT Pub. No. WO95/09569 PCT Pub. Date Apr. 13, 1995A medical drill for drilling holes in a bone or cartilage is formed with an end drill section. The end drill section has a specially formed drill tip at the distal end. The drill tip includes a flattened section which is located diametrically in relation to the central axis of the drill. The drill may be formed on the end of a router to provide a single loop to drill a pilot hole and then continue with the routing process. The drill section minimizes the heat created within the bone or cartilage.
