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 AlOlayer. The AlOlayer 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 AlOlayer. An average distance between the plurality of first protrusions is 70-120 nm. 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.

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 AlOlayer. The AlOlayer 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 AlOlayer. 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. An average number of the second protrusions in the composite protrusion is 1.4 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.

The intermediate layer includes a plurality of first protrusions protruding toward the AlOlayer. 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.

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 AlOlayer in this order from a side of the base. The AlOlayer 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 AlOlayer. An average area of the plurality of first protrusions is 1700 nmor 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.

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 AlOlayer. The AlOlayer 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 plurality of first protrusions that project toward the AlOlayer, and a beam that extends in a direction intersecting a direction in which the first protrusions project, to connect the first protrusions. A cutting tool of the present disclosure is provided with: a holder extending from a first end toward a second end and including a pocket on a side of the first end; and the above-described coated tool located in the pocket.
