More Information
Summary:PROBLEM TO BE SOLVED: To provide a diamond coated cutting tool which improves the deposition of a workpiece and the flow of cutting chips by reducing the coefficient of friction between a cutting chip and a diamond coat film by making the large unevenness of the surface of the workpiece gentle without spoiling the abrasion resistance of the cutting edge of the diamond coated cutting tool in a dry and semi-dry machining. SOLUTION: The diamond coat film is formed on and near the cutting edge of a cutting tool base body made of cemented carbide alloy, and a protective film excellent in lubricity is coated on the surface of the base body including the diamond coat film section.
