[Scope of Claim for Utility Model Registration] A tool body having a cylindrical shape and having a groove opening on the outer peripheral surface and a guide hole extending in the axial direction of the cylinder and opening into the groove; A first plunger is mounted so as to be linearly movable in a direction intersecting the axis of the main body, and a first plunger is slidably inserted into the guide hole and provided so as to be able to come into contact with the proximal end side of the first plunger. a second plunger; and a resilient member configured to project the second plunger toward the first plunger; A pressing surface is formed that gradually separates from the opening of the groove as the springing member moves toward the springing direction, and a pressing surface is formed at the tip of the first plunger that gradually moves away from the axial ends of the tool body toward the center. A chamfering tool characterized in that two cutting blades protruding outward in the radial direction of the main body are disposed so as to be able to move in and out of the outer peripheral surface of the tool main body as the first plunger moves.
