摘要： A cutting insert for threading of the present invention includes two opposing end surfaces and a peripheral side surface extending therebetween. The peripheral side surface has a first side surface portion and a second side surface portion arranged at different positions in a circumferential direction. A cutting edge is formed at an intersecting ridgeline portion between the first end surface and the first side surface portion and at least a portion of this cutting edge has a shape corresponding to a thread groove. The second side surface portion has an inclined portion which enlarges outward from the side of the first end surface toward the side of the second end surface. This inclined portion is configured to engage with a side wall surface of a tool body so as to prevent floating of the cutting insert.

摘要： A threading cutting insert achieves high shape accuracy of a screw to be processed, and saves on manufacturing cost. Therefore in the threading cutting insert, a plurality of tooth-shaped cutting edges are formed in a cross ridge line portion between a rake face and flanks formed in a cutting side face, wherein the plurality of mountain-shaped cutting edges provides at least one finishing cutting edge for transferring a shape of a screw, and at least one roughing cutting edge formed in a tooth shape smaller than that of the finishing cutting edge. A flank of the finishing cutting edge includes a first flank, and a second flank having a clearance angle larger than that of the first flank, wherein the finishing cutting edge, the first flank, and the second flank are sequentially provided in that order from the rake surface in a direction of a lower surface of the insert.
