Claims

[Claims for Utility Model Registration] (1) A tip attachment provided at the tip of the cutter body, which has the shape of a parallelogram flat plate in appearance with upper and lower surfaces parallel to each other, and one of the upper and lower surfaces is used as a seating surface. In a throw-away tip for thread cutting that is positioned and fixed in contact with the mounting bottom surface of the seat, with its two adjacent side surfaces in contact with the mounting surface of the tip mounting seat, and with the other of the upper and lower surfaces as a rake surface, the front and back sides of each other are fixed. A flank is formed on at least a pair of two side faces located at the rake face, and a cutting edge for thread cutting is formed at the intersecting ridge of the flank and the rake face, and the flank is connected to the cutting edge. a first relief surface attached thereto; and a flat surface provided on the seating surface side of the first relief surface, having a relief angle larger than the first flank surface and capable of coming into close contact with the mounting side surface of the chip mounting seat. A throw-away tip for a thread cutter, characterized in that it is constituted by a second flank surface having a second flank surface. (2) A utility model according to claim 1, characterized in that at least a seating surface along the second flank is formed with a flat surface that can come into close contact with the mounting bottom surface of the chip mounting seat. Throwaway tip for thread cutter.
