摘要： A cutting insert has an upper surface, a lower surface, a plurality of side surfaces connecting the upper surface and the lower surface and a central hole formed at a central portion thereof. The cutting insert has a flat seating surface formed on a highest level of the upper surface, a plurality of side cutting edge portions formed at intersections of the upper surface and the side surfaces, and a corner cutting edge portion formed at an intersection of two adjacent side cutting edge portions and having a cutting edge formed at a front end thereof. A land portion, a downward inclined surface, a corner bottom surface, a first protrusion, an upward inclined surface and the seating surface are formed on the corner cutting edge portion sequentially along a diagonal line directed from the cutting edge to the central hole. A pair of second protrusions are formed and disposed symmetrically on both sides of the diagonal line so that the corner bottom surface is surrounded by the downward inclined surface, the first protrusion, and the second protrusions, and the corner bottom surface has the smallest height and the seating surface has the largest height along the diagonal line.

摘要： An insert clamp secures a cutting insert having a central hole to a tool holder. The clamp includes a forward protrusion to be received in the central hole of the insert, a central body portion provided with a pressing part to press down the upper surface of the insert and a screw hole for a clamping screw to pass through, and a rear protrusion having a rear contact surface to come in contact with a rearward slanting surface of the tool holder. The forward protrusion is formed on the forward end of the insert clamp, an inside surface of the forward protrusion extends downward in a spaced state apart from the inner wall of the central hole of the insert, and a distal portion of the inside surface the forward protrusion is provided with a protuberance of convex curved surface to come in tangential contact with the inner wall of the insert. The pressing part is formed on the bottom surface of the central body portion of the insert clamp, and has convex curved surfaces to come in tangential contact with the upper surface of the insert on both regions of the bottom surface of the central body portion which is bisected by a central line passing through the forward protrusion and the screw hole.
