摘要：
A coated cBN sintered body has excellent wear resistance, fracture resistance, adhesiveness between a substrate and a coating, and a tool life of which is elongated as compared with conventional cBN sintered bodies. The coated cBN sintered body has a cBN sintered body substrate and a coating coated on the surface thereof. The cBN sintered body includes 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.
