Claims

[Claims for Utility Model Registration] (1) A groove portion on the outer periphery of the tip of the tool body, which has two wall surfaces facing each other, and the distance between the two wall surfaces becomes narrower toward the center in the radial direction of the tool. A throw-away chip is inserted into this groove, and a wedge member is inserted between the throw-away chip and one wall surface of the groove, so that the throw-away chip is connected to the wedge member and the other wall of the groove. In the throw-away type cutter held between the wedge member and the wall surface, one of the side surfaces of the wedge member that contacts one of the wall surfaces of the groove portion has an extension extending in a direction perpendicular to the insertion direction of the wedge member. forming a first recessed portion that is present and recessed inwardly of the wedge member;
A throw-away cutter characterized in that the angle of inclination of the other side surface that contacts the throw-away tip with respect to the one side surface is set to be larger than the angle of inclination of the other wall surface of the groove with respect to one wall surface. (2) A second recessed portion is provided on one wall surface of the groove portion, the second recessed portion recessed from the one wall surface and extending in a direction intersecting the first recessed portion of the wedge member. The throw-away cutter according to claim 1.
