Abstract

A drilling and abrasion tool for bony materials comprises a hollow cylindrical tool shaft (1) carrying an annular abrasive head (3) on its front end. The abrasive head (3) is provided with an abrasive grain material on its surface. The front face of the abrasive head (3) has sharp edges at its inner edge (4a) and/or its outer edge (4b). This prevents lateral migration of the abrasive head (3) on penetration into softer bony material and cartilaginous material.
