Abstract

PURPOSE:To effectively prevent the breakage at the blade tip of a tapered reamer portion by providing a reamer portion at the tip of a tapered reamer portion maintaining the same diameter, forming the blades of both reamer portions in the form of screw teeth, and providing a drill blade at the tip of the reamer portion of the same diameter, so that the cutting resistance is reduced.
