An object of the present invention is to provide a coated tool excellent in adhesiveness of a film, wear resistance, crater resistance and chipping resistance. The coated tool is a coating tool comprising a substrate and a coating coated on the surface thereof, at least one layer of the coating being an ±-type aluminum oxide film, an average film thickness of the ±-type aluminum oxide film being about 0.5 to about 10 µm, an average grain size of the ±-type aluminum oxide film being about 0.5 to about 1.5 µm, and a texture coefficient TC A (012) of (012) plane of the ±-type aluminum oxide film and a texture coefficient TC A (104) of (104) plane of the ±-type aluminum oxide film satisfying TC A (104)/TC A (012)‰§2.0. |
