Abstract

The present invention addresses the problem of improving the lifespan of cBN cutting tools used in cutting heat resistant alloys. The cBN cutting tool is equipped with: tool edge tips formed of a cBN sintered compact that uses cBN particles of 0.5 µm to 2 µm mean particle diameter and has a thermal conductivity of 20- 70 W/m·K; and an alloy that holds said tool edge tips on the corners. The cutting edge provided on the tool edge tips of said tool is given a positive rake angle.
