Abstract
A coated tool includes a base and a coating layer located on the base. The coating layer includes a first layer having a thickness of 1 μm or more located near the base, and a second layer including AlOparticles which is in contact with the first layer and is located more away from the base than the first layer. A difference (A−A) between an erosion ratio Ain the second layer and an erosion ratio Ain the first layer is 0.60 to −0.30 μm/g. The erosion ratio is obtained by collision of a liquid A in which 3 mass % of spherical AlOparticles having a mean particle diameter of 1.1-1.3 μm is dispersed in pure water. A cutting tool includes a holder which includes a pocket, and the coated tool located in the pocket.
