Abstract:
A cutting edge tip of a cubic boron nitride sintered body has improved joint strength to a substrate of a cemented carbide. A cutting edge tip of a cubic boron nitride sintered body has improved crater wear resistance. A tool  10  of the present invention includes a substrate  12  of a cemented carbide and a cutting edge tip  14  of a cubic boron nitride sintered body joined to the substrate  12 . The cutting edge tip  14  has a thickness covering an upper surface  12 a  to a lower surface  12 b  of the substrate  12 . The cubic boron nitride sintered body contains 50 volume % or more and 95 volume % or less of cubic boron nitride and 5 volume % or more and 50 volume % or less of a binder phase. The cubic boron nitride has an average grain size of 1.0 μm or more and 6.0 μm or less.

Claim (Index 10):
The tool according to  claim 2 , wherein a joint surface of the cutting edge tip and the substrate contains a curved area.
