    摘要： This invention provides a surface-coated cutting tool which exhibits excellent fracture resistance and wear resistance in high-speed cutting, such as high-speed gear cutting, high-speed milling, and high-speed drilling. The surface-coated cutting tool includes a hard coating layer composed of an alternately laminated layer structure of at least a thin layer A and a thin layer B formed on the surface of a tool substrate, such as a cemented carbide substrate, a cermet substrate, and a high-speed tool steel substrate. The thin layer A is an (Al, Cr, Si)N layer which satisfies a compositional formula: [AlxCrySiz]N (0.2≤X≤0.45, 0.4≤Y≤0.75, 0.01≤Z≤0.2, and X+Y+Z=1 in terms of atomic ratio). The thin layer B is an (Al, Ti, Si)N layer which satisfies a compositional formula: [AluTivSiw]N (0.05≤U≤0.75, 0.15≤V≤.94, 0.01≤W≤50.1, and U+V+W=1 in terms of atomic ratio).
