Abstract: A hard film-coated cutting tool comprises: a hard base material and a hard film formed on the hard base material, wherein: assuming that a colorimetric diffusion reflectance value is LSCER and a total reflectance value is LSCIR, the relationship of 0.65?LSCER/LSCIR?0.85 is satisfied, and when surface roughness is measured on the rake surface of the hard film within the range of 100 ?m from the edge, an arithmetic average height SaR is within the range of 0.2 ?m?SaR?0.5 ?m; and assuming that, at a flank surface of the hard film, a colorimetric diffusion reflectance value is LSCEF and a total reflectance value is LSCIF, the relationship of LSCEF/LSCIF?0.9 is satisfied, and when surface roughness is measured on the flank surface of the hard film within the range of 100 ?m from the edge, an arithmetic average height SaF is within the range of 0.15 ?m?SaF?0.4 ?m.

Abstract: The purpose of the invention is to provide a hard coating for cutting tools, wherein the hard coating is excellent in wear resistance and oxidation resistance, as well as in hardness properties. In order to achieve the purpose, the invention may provide a cutting tool which includes a hard substrate and a hard coating formed on the hard substrate, wherein the hard coating has a structure in which a first sub-coating having a composition range represented by [Formula 1] below and having a cubic structure, and a second sub-coating having a composition range represented by [Formula 2] below and having a cubic structure are alternately stacked.
