ローアウエイチツプ。[Claims for Utility Model Registration] It has a polygonal plate shape, and the other square surfaces have a narrow land 4 with the central boss surface 2 remaining.
In the indexable chip in which a chip breaker groove 5 is formed and a cutting edge ridge 12 is formed at the outer peripheral edge of the tip, the land 4 has the cutting edge ridge 12 formed by intersecting with the circumferential side. The tip breaker groove 5 has a straight cutting edge 12a near the nose 11, and is uneven so as to have at least one concave cutting edge 12b toward the center of the side, and the chip breaker groove 5 has an inclination angle θ. A front circumferential protrusion 7 is formed following the inclined surface 6, and the width of the groove changes to increase due to the presence of the apex portion 9 extending from the central boss surface 2, and at the tip of the apex portion 9, A nose protrusion 10 is formed,
Moreover, the throw-away chip is characterized in that the projection 7 on the entire circumference has a concavity and convexity that corresponds to the concavity and convexity of the land 4.
