摘要： 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 0.1 μm. 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 0.3 μm 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.

摘要： A cutting tool including a base member and a coating layer. The base member includes a rake face and a flank face. The coating layer has a composition represented by a first chemical formula of CraM1-a(C1-xNx), wherein M represents at least one selected from Ti, Al, Si, W, Mo, Ta, Hf, Nb, Zr, and Y, 0.01≦a≦0.5, and 0≦x≦1. The coating layer is disposed on the base member and includes a cutting edge at an intersecting ridge line between the rake face and the flank face. The coating layer further comprises droplets thereon. An average composition of the droplets disposed on the rake face has a Cr content higher than the Cr content of the average composition of the droplets disposed on the flank face.

摘要： A cutting tool with a substrate which is coated with a coating layer containing TiaAlbNbdMe(C1-xNx), where M represents one or more elements selected from among Si, W, Mo, Ta, Hf, Cr, Zr and Y, where 0.1≦a≦0.7, 0≦b≦0.8, 0.02≦d≦0.25, 0≦e≦25, a+b+d+e=1.0 and 0≦x≦1 and is provided with a rake face; a flank face; a cutting edge between the rake face and the flank face; and droplets on the surface of the coating layer. The droplets include finer droplets having particle diameters of 300 nm or less; and coarser droplets having particle diameters of 1000 nm or more. The flank face has a higher percentage of the finer droplets than the rake face. An Nb content in the coarser droplets on the flank face is higher than an Nb of the coarser droplets on the rake face.
