COATED SINTERED CBN
This is to provide a coated cBN sintered body which has excellent wear resistance, fracture resistance, adhesiveness between a substrate and a coating, and a tool life of which can be elongated as compared with the conventional ones. The coated cBN sintered body comprising a cBN sintered body substrate and a coating coated on the surface thereof, wherein the cBN sintered body comprises 76 to 90% by volume of cBN, and 10 to 24% by volume of a binder phase and inevitable impurities, an average grain size of cBN is 0.5 to 5.0 µm, an average value of the thickness of the binder phase is 0.05 to 0.8 µm, and the standard deviation of the thickness of the binder phase is 0.8 µm or less.
