    摘要： The invention relates to a rotatable and reversible cutting attachment (1) cutting eight ways and comprising two opposing, essentially quadratic base surfaces (2) which can be mutually rotated about a central axis (A1) extending perpendicularly to said surfaces, and four identical lateral surfaces (3). A main cutter is formed between each base surface (2) and each lateral surface (3), extending only over part of the length of the lateral surface (3). Each lateral surface (3) comprises two diagonally opposed circular or curved corner edges (5) forming a secondary cutter (6) adjacent to each main cutter (4). Each lateral surface also comprises two chip cavities (7) which are set in the lateral surface (3) and extend from each corner edge (5) along the main cutter associated with the edge, up to a rear end of the chip cavity (7d).

    摘要： A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes a hard layer. The hard layer includes a plurality of crystal grains having a sodium chloride-type crystal structure. When the angle of intersection between the normal direction to (111) plane that is a crystal plane of the crystal grain and the normal direction to the surface of the base material is measured using an EBSD system for a cross section of the hard layer that is parallel to the normal direction of the surface of the base material, a proportion A of the crystal grains having the angle of intersection of 0 degree or more to less than 20 degrees is 50% or more. With respect to the boundaries of the crystal grains, the length of Σ3 grain boundaries is less than 50% of the length of Σ3-29 grain boundaries. The crystal grain has a layered structure in which a first layer composed of nitride or carbonitride of Al x Ti 1-x and a second layer composed of nitride or carbonitride of Al y Ti 1-y are alternately stacked. The total thickness of the first layer and the second layer adjacent to each other is 3 nm or more and 40 nm or less.

    摘要： An object is to provide a cutting insert for a milling cutter with which efficiency in machining can be increased. The cutting insert includes two polygonal main surfaces facing each other and side surfaces each connected to a corresponding side of each of the main surfaces. The side surfaces include a major side surface through which an attachment hole extends, a first minor side surface perpendicular to the major side surface, and a second minor side surface disposed between the first minor side surface and the major side surface. A ridge between each of the main surfaces and the major side surface forms a major cutting edge, and a ridge between each of the main surfaces and the second minor side surface forms a minor cutting edge. An angle between the major cutting edge and the minor cutting edge is 145° or larger.

    摘要： A cutting insert 1 according to an embodiment of the present invention has an upper surface 3, a lower surface 5, a side surface 7 connected to each of the upper surface 3 and the lower surface 5, and a cutting edge 9 located along an intersection of the upper surface 3 and the side surface 7. The upper surface 3 has a land surface 13 disposed along the cutting edge 9, a rake surface 15 which is located further inside than the land surface 13 and is inclined so as to have a smaller height as departing from the land surface 13, and a bottom surface 17 located further inside than the rake surface 15. The rake surface 15 has a projection-shaped first region 23 and a concave-shaped second region 25 which are alternately disposed along the bottom surface 17. The first region 23 has a first recess 27 that reaches the second region 25 adjacent to the first region 23.
