徴とするトレパニングツール。A recess extending in the axial direction of the tool body is provided in the center of the tip of the tool body, and a cutting edge is provided on the outer periphery of the tip of the tool body. In the trepanning tool, the core, which is the uncut portion, is allowed to grow relatively into the recess, and an extrusion member whose tip end protrudes into the recess is moved in the axial direction of the tool body at the bottom of the recess. A spring member is provided between the extrusion member and the tool main body, and the drilling is performed by the core from the time when the depth reaches a predetermined depth until the time when the hole is penetrated. A trepanning tool characterized in that the spring member is elastically deformed by pressing an extrusion member, and the core is pushed out from the recess by the elastic restoring force of the spring member during penetration.
