Claims

[Scope of Claim for Utility Model Registration] (1) The cutting edge is removably attached to the outer periphery of the tip of a tool body that is rotated around an axis, and the cutting edge located on the outer periphery of the tool body has an arc shape; In a throw-away chip in which a minor cutting edge is formed on the rear end side of the cutting edge, which is inclined from this cutting edge toward the tool body side, between the above-mentioned cutting edge and the minor cutting edge, there is a A throw-away chip characterized by forming an inclined cutting edge that is inclined at 1 to 5 degrees and smoothly connects the cutting edge and the auxiliary cutting edge. (2) The throw-away tip according to claim 1, wherein the blade length of the inclined cutting blade is 1/5 to 1/4 of the blade length of the arc-shaped cutting blade.
