摘要： There is provided an extremely practical diamond coating for a cutting tool that has excellent adhesion to a cemented carbide base metal, high hardness and adequate abrasion resistance with respect to a nonferrous high-hardness work material, and the ability to significantly extend the service life of a cutting tool. The diamond coating for a cutting tool is formed on a substrate, wherein the diamond coating for a cutting tool is configured so that the diamond coating includes at least one or more layers of a multilayer coating layer in which one or more layers of each of a first coating layer having an average crystal particle diameter of 0.3 3 µm or greater and 3 µm or less and a second coating layer having a larger average crystal particle diameter than the first coating layer are layered in alternating fashion, and the first coating layer is formed having a film thickness of 1 µm or greater and 10 µm or less directly on the substrate.
