摘要： A cutting tool is made of a cemented carbide including a first hard phase and a binder phase. The first hard phase is composed of WC particles. The binder phase contains Co and/or Ni. The cutting tool includes a main body part and a surface layer part. A thickness of the surface layer part is equal to or less than an average particle diameter of the first hard phase. On a surface of a plain part in a rake face, 1.0 GPa or more of a compressive residual stress is applied to the first hard phase. A ratio (B/A) of the average particle diameter (B) of the first hard phase on the surface of the plain part in the rake face to an average particle diameter (A) of the first hard phase on a cross section of the main body part is 0.7 or more and less than 1.

摘要： A coated tool according to the present disclosure comprises a base body and a coating film. The base body contains a plurality of boron nitride particles. The coating film is located on the base body. In addition, in a case where a hardness is measured by pressing an indenter from a surface of the coating film to a depth of 20% of the coating film while changing an indentation load of the indenter, a maximum hardness difference, which is a difference between a maximum hardness and a minimum hardness of the hardness, is 4 GPa or more.

摘要： A coated tool in a non-limiting embodiment of the present disclosure includes a base and a coating film located on the base. The coated tool includes a first surface, a second surface adjacent to the first surface, and a cutting edge located on at least a part of a ridge part of the first surface and the second surface. The coating film includes an AlTiN film including Ti, Al and N. A first Al ratio and a second Al ratio are 0.7 or more. The first Al ratio is Al/(Al+Ti) at a point located 0.1 mm away from the cutting edge, and the second Al ratio is Al/(Al+Ti) at a point located 0.2 mm away from the cutting edge in the first surface. The second Al ratio is larger than the first Al ratio.

摘要： A cutting insert according to one embodiment includes: a rake face; a flank face continuous to the rake face; and a cutting edge constituted of a ridgeline between the rake face and the flank face. A coolant flow path is provided inside the cutting insert. One end portion of the coolant flow path opens in the flank face to form a coolant ejection hole. The flank face is provided with a coolant guide groove extending from the coolant ejection hole toward the cutting edge with a base end portion of the coolant guide groove being connected to the coolant ejection hole and with a front end portion of the coolant guide groove being disposed at a position close to the cutting edge relative to the base end portion.
