摘要： A cutting edge exchange type cutting tool is provided which can suppress a variation of the position of a cutting edge due to turning moments of a plurality of different directions acting on a cutting insert by a fastening force of a screw or a force of a cutting resistance during a cutting work. A chip seat (21) has a bottom surface (26) and first and second wall surfaces (22, 24). A cutting insert (30) has a first inclined surface part (35) and a second inclined surface part (36). In the first wall surface (22), a first abutting part (23) which abuts on the first inclined surface part (35) is formed. In the second wall surface (24), a second abutting part (25) which abuts on the second inclined surface part (36) is formed. The first and second inclined surface parts (35, 36) are formed with flat surfaces. The first inclined surface part (35) is inclined at an obtuse angle to the bottom surface (26). The second inclined surface part (36) is inclined at an acute angle to the bottom surface (26).

摘要： A cutting insert is provided which enables a reduction in cutting resistance and stable process. The insert includes a chip breaker groove formed inside corner cutting edges and a raised portion. The raised portion includes a top surface, a front raised surface, and side raised surfaces. The top surface crosses the front raised surface and each of the side raised surfaces. A first intersecting portion at which the front raised surface and the top surface intersects with each other is linearly extended. A second intersecting portion at which each of the side raised surfaces and the top surface intersect with each other is extended from a corresponding one of opposite sides of the first intersecting portion so that a distance from the corresponding side cutting edge increases gradually with a distance from the corner cutting edge. The front raised surface and the side raised surfaces are curved convexly outward.
