Claims

[Claims for Utility Model Registration] (1) In a throw-away chip whose lower surface is used as a seating surface and whose upper surface is used as a rake surface and is attached to the outer periphery of the tip of a tool body that rotates about an axis, Forming a peripheral cutting edge with a smooth convex curve on the ridgeline located on the outer peripheral side of the tool body,
An inner circumferential cutter is formed on the ridge line located on the inner circumferential side of the tool body, and the contact surface with the tool body that receives the feeding force of cutting by the outer circumferential cutter and the inner circumferential cutter is formed on the outer circumferential side surface, respectively. A throw-away tip characterized by being formed in a location other than the above. (2) The upper surface has a corner portion sandwiched between the outer peripheral cutter and the inner peripheral cutter formed by an inclined surface in which the thickness between the upper and lower surfaces gradually decreases from the center of the upper surface toward the corner portion. 1. A throw-away tip according to claim 1, characterized in that the throw-away tip is formed as follows.
