摘要： A head replaceable cutting tool having a structure that can limit a machining cost when a clearance portion is formed in a portion at which a head is attached and detached, and also limit deformation of a shank is provided. The head replaceable cutting tool includes: a projection portion or a hole portion for attachment and detachment disposed in a head; a shank to which the head is attachable; a hole portion, to which the projection portion is removably attachable along a central axis, or a projection portion disposed in an end portion of the shank; a fastening member that presses the projection portion toward an inner circumference surface of the hole portion; and a fastened portion disposed in the shank to fasten the fastening member. The hole portion has a transverse cross-sectional shape that is a substantially circular shape having a curvature radius R1, and the projection portion has a transverse cross-sectional shape including a contact portion at which an outer circumference surface of the projection portion is in contact with the inner circumference surface of the hole portion and a clearance portion that is formed in a part of the outer circumference surface so as to deviate radially inward from a virtual circle corresponding to the inner circumference surface and does not come into contact with the inner circumference surface.

摘要： Single-cutting-edged solid cutting insert (12) with a step in the lower portion. The insert comprises: opposite insert first and second side surfaces (28A; 28B); an insert plane (PI) parallel with and located midway between the insert side surfaces (28A; 28B); an insert peripheral surface (30) connecting the insert side surfaces (28A; 28B); a first corner region (R1) located in an upper-rear portion of the cutting insert; a second corner region (R2) located in an upper-front portion of the cutting insert; a third corner region (R3) located in an lower-front portion of the cutting insert; and a fourth corner region (R4) located in an lower-rear portion of the cutting insert. T he insert peripheral surface (30) comprises: a peripheral upper sub-surface (30A) extending from the first corner region (R1) to the second corner region (R2); a peripheral front sub-surface (30B) extending from the second corner region (R2) to the third corner region (R3); a peripheral lower sub-surface (30C) extending from the third corner region (R3) to the fourth corner region (R4); and a peripheral rear sub-surface (30D) extending from the fourth corner region (R4) to the first corner region (R1). T he first corner region (R1) comprising: an insert upper abutment surface (32A) formed at the peripheral upper sub-surface (30A) and extending forward of the peripheral rear sub-surface (30D); and an insert rear abutment surface (32B) formed at the peripheral rear sub-surface (30D) and extending downward of the peripheral upper sub-surface (30A). T he second corner region (R2) comprises: a single cutting edge (34) only, the single cutting edge connecting the insert side surfaces (28A; 28B) and being wider than adjacent portions of the peripheral upper and front sub-surfaces (30A; 30B). T he third corner (R3) comprises: an insert first lower abutment surface (32C) formed at the peripheral lower sub-surface (30C) and extending rearward of the peripheral front sub-surface (30B); and an insert second lower abutment surface (32D) formed at the peripheral lower sub-surface (30C) and extending downward of the insert first lower abutment surface (32C).

摘要： A cutting insert (20) has a cutting edge (26) formed at an intersection of a rake surface (28) and a relief surface (30), with a chip-control arrangement (22) located at the rake surface (28). The chip-control arrangement (22) includes a plurality of recesses (50, 74) that extend downwardly into the rake surface (28) and a plurality of projections (52, 72) that extend upwardly from the rake surface (28). The plurality of recesses (50, 74) follow a pattern of increasing depth in a rearward direction (DR) from the forward portion (25) of the cutting edge (26). The plurality of projections (52, 72) follow a pattern of increasing height in a rearward direction (DR) from the forward portion (25) of the cutting edge (26).

摘要： A multi - grooving tool holder for holding cutting members (14) seated in a side-by- side formation in a clamping portion (16) of the holder. The clamping portion (16) includes an upper clamp (20) and a lower clamp (22) and an elastic member (58) is located in one of the upper and lower clamps. When cutting members (14) are assembled in the clamping portion(16), the elastic member (58) engages the cutting members and aligns each cutting member independently, by applying a force, and consequently a moment on the cutting members.
