摘要： A sintered material containing high-pressure phase-type boron nitride and a binder is provided. The high-pressure phase-type boron nitride is contained in an amount of from 50% to 78% by volume, and the balance is a binder phase. The binder phase comprises at least one selected from the group consisting of nitride, carbide, carbonitride, and boride of Ti, nitride, boride and oxide of Al, carbide and boride of W, nitride, carbide, carbonitride and boride of Co, and carbide and boride of Ni, or a mutual solid solution thereof. The binder phase forms a binder phase which is continuous in a sintered material texture. The weight of metal components Al, W, Co and Ni which are present as compounds in the sintered material is from 3% to 20% based on the sintered material. The sintered material is excellent in crater resistance and capable of realizing a long tool life, even under the condition that the temperature of the cutting edge becomes high and the impact is large, as in high-speed interrupted cutting of hardened steel where the cutting speed V becomes at least 150 m/min.
