    Abstract: PROBLEM TO BE SOLVED: To provide a cutting insert that achieves extremely low-depth cutting or finishing cutting without impairing a chip treatment performance and that has a long service life even if used for medium-depth cutting. SOLUTION: In the cutting insert, a projected portion 5 is formed on a rake face 2 inside the corner section 4A of a cutting blade 4; a pair of convex portions 7 extends to both sides toward the cutting blade 4 from the wall surface 5D of the projected portion 5 to the rake face 2 with a bisector L of the corner section 4A therebetween; a first wall surface 7A of these convex portions 7 facing the corner section 4A and a second wall surface 7B intersecting with the first wall surface 7A at the intersecting ridgeline M form an inclined surface toward the rake face 2 as the first and second wall surfaces depart from the intersecting ridgeline M; the intersecting ridgeline M intersects with the wall surface 5D at a lower position than the top portion 5C on the side of the corner section 4A of the projected portion 5; and a back wall 8C extending across the bisector L is located on the rake face 2 on the side of the corner section 4A nearer than the protrusion portion 7, the back wall being between the corner section 4A and the convex portion 7 and forming a concave portion 8 for constituting the concave portion for the cutting blade 4 on the corner section 4A.

    Abstract: PROBLEM TO BE SOLVED: To provide a polygonal turning insert having primary cutting edges (12), which individually include a nose edge (14) and two main edges (15) which converge toward the nose edge (14).SOLUTION: Behind the nose edge, chip-directing guide surfaces are formed, namely, on one hand, with a breast surface (24) included in a knob (20) situated behind the nose edge along a bisector between main edges(15), and, on the other hand, with a pair of flank surfaces (21) included in a land there behind. According to the present invention, at a distance behind the knob (20), there is formed a second breast surface (25), an upper part of which is situated on a higher level than the upper part of the first breast surface (24). In such a way, it is guaranteed that thin chips, which tend to pass or jump over the first breast surface without being affected by the same, will impinge on the second, higher breast surface and be subjected to guiding by the same.
