摘要： A coated tool in the present disclosure includes a base and a coating layer located on a surface of the base. The coating layer includes an intermediate layer including Ti, and an Al2O3 layer. The Al2O3 layer is located in contact with the intermediate layer at a position further away from the base than the intermediate layer. The intermediate layer includes a plurality of first protrusions protruding toward the Al2O3 layer. At least one of the plurality of first protrusions is a composite protrusion including second protrusions protruding in a direction intersecting with a protruding direction of the first protrusions. A percentage of the composite protrusions in the plurality of first protrusions is 30% or less. A cutting tool in the present disclosure includes a holder which is extended from a first end toward a second end and includes a pocket on a side of the first end, and the coated tool located in the pocket.

摘要： A coated tool includes a base and a coating layer on the base. The coating layer includes a first layer including Al2O3 particles, and a second layer on the first layer. The second layer includes, sequentially from the base, a first film, a second film in contact with the first film, and a third film in contact with the second film. The first to third films individually include Ti. The first film, the second film and the third film individually include at least one kind selected from C and N. The coated tool satisfies a relationship of a first N content>a third N content>a second N content, in which the first N content is an N content in the first film, the second N content is an N content in the second film, and the third N content is an N content in the third film.

摘要： A coated tool in the present disclosure includes a base and a coating layer located on a surface of the base. The coating layer includes a TiCN layer, an intermediate layer including Ti, and an Al2O3 layer in this order from a side of the base. The Al2O3 layer is located in contact with the intermediate layer at a position further away from the base than the intermediate layer. The intermediate layer includes a plurality of first protrusions protruding toward the Al2O3 layer. An average area of the plurality of first protrusions is 1700 nm2 or less. A cutting tool in the present disclosure includes a holder which is extended from a first end toward a second end and includes a pocket on a side of the first end, and the coated tool located in the pocket.

摘要： A coated tool of the present disclosure is provided with a base member and a coating layer located on a surface of the base member. The coating layer includes a TiCNO layer and an Al2O3 layer. The Al2O3 layer is located in contact with the TiCNO layer at a position farther from the base member than the TiCNO layer is. The TiCNO layer includes a composite protrusion including a first protrusion that projects toward the Al2O3 layer, a second protrusion that projects from the first protrusion in a direction intersecting a direction in which the first protrusion projects, and a third protrusion that projects from the second protrusion in a direction intersecting the direction in which the second protrusion projects.
