摘要:
A cutting tool made of a surface-coated cubic boron nitride-based ultra-high-pressure sintered material, comprising a cutting insert main body formed by ultra-high-pressure sintering of a compact composed of titanium nitride, aluminum and/or aluminum oxide, and boron nitride, and a hard coating layer vapor deposited on the main body. The main body has a texture containing cubic boron nitride, titanium nitride and reaction product. The hard coating layer has a lower layer of nitride having a composition of [Ti1-X-YAlXSiY]N, where X is in a range from 0.40 to 0.60 and Y is in a range from 0.02 to 0.10 in an atomic ratio, and the upper layer comprises a thin layer A having the composition of [Ti1-X-YAlXSiY]N, where X is in a range from 0.40 to 0.60 in an atomic ratio and Y is in a range from 0.02 to 0.10, and a thin layer B consisting of a Ti nitride (TiN). The upper layer consists of the thin layer A and a thin layer B layered alternately.
