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 8):
The tool according to any one of  claim 1 , wherein the binder phase contains a compound including at least one metal selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Al, and Co and at least one element selected from the group consisting of carbon, nitrogen, oxygen, and boron.
