Claims

[Claim for Utility Model Registration] A disc-shaped throw-away chip is placed on a groove-shaped chip mounting seat formed in the cutter body, and this throw-away chip is placed between the rake face and the above-mentioned chip mounting seat. In a throw-away type cutter fixed by a wedge member provided on the tip, the throw-away tip has a flank with a clearance angle of 30° to 45°, and an intersection between the rake face and the flank. The wedge member is honed, and the corner portion between the end face located on the outer peripheral side of the cutter body and the side face located on the tip side is A throw-away cutter characterized by being formed by a plurality of inclined surfaces whose inclination angle with respect to the end surface gradually increases.
