Claims

[Claims for Utility Model Registration] 1. The whole is formed into a polygonal flat plate shape, and at least one end surface has a cutting blade having a nose portion and a chip breaker in order from the periphery inward. A recess extending along the cutting edge is formed in the indexable tip, in which a groove is formed in a portion of the bottom of the recess corresponding to the nose portion, from the inside of the one end surface toward the outside of the nose portion. 1. A throw-away chip characterized in that a plurality of convex portions are formed in sequence, and the height of the convex portion on the nose portion side is lower than the height of the convex portion on the inner side. 2. The indexable tip according to claim 1, wherein the plurality of convex portions have equal widths. 3. The indexable tip according to claim 1, wherein the plurality of convex portions have a width wider on the nose side than on the inner side. 4. According to any one of claims 1 to 3 of the utility model registration claim, wherein the innermost protrusion among the plurality of protrusions is in contact with a portion of the one end surface that is inner than the concave part. Throwaway tips listed. 5. The indexable tip according to any one of claims 1 to 3, wherein the plurality of convex portions are spaced apart from a portion inside the concave portion of the one end surface. 6. Utility model registration claims 1 to 5, characterized in that the innermost protrusion among the plurality of protrusions has the same height as the portion of the one end surface that is inner than the concave part. Throwaway tip listed in either. 7. The indexable tip according to any one of claims 1 to 6, wherein the plurality of convex portions are in contact with each other. 8. The indexable tip according to any one of claims 1 to 6, wherein the plurality of convex portions are spaced apart from each other.
