Hard coating for cutting tools with excellent wear resistance

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 as 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.
