简介 A surface coated tool including a substrate, and stacked layers composed of two coating layers represented by the following general formula (1) on the substrate is provided. A first coating layer to be coated on the surface of the substrate, which has a thickness of 0.1 to 1 µm, is composed of a granular crystal having a mean crystal diameter of 0.01 to 0.1µm. A second coating layer to be coated on the surface of the first coating layer, which has a thickness of 0.5 to 5 µm, is composed of columnar crystal grown in a direction perpendicular to the substrate, and the columnar crystal has a mean crystal width of 0.05 to 0.3µm in a direction parallel to the substrate while a mean crystal width thereof is larger than the mean crystal diameter of the first coating layer.         [Formula 3] M1-aAla(CbN1-b)     (1) wherein, M represents at least one metal element selected from the group consisting of the elements of Groups 4, 5 and 6 of the periodic table, Si and rare earth elements, "a" satisfies the relation of 0.25 ≤ a ≤ 0.75, and "b" satisfies the relation of 0 ≤ b ≤ 1.
