SURFACE-COATED BORON NITRIDE SINTERED BODY TOOL
This surface-coated boron nitride sintered tool is provided with a cubic boron nitride sintered compact and a coating film (100) that is formed on the cubic boron nitride sintered compact. The coating film (100) comprises a layer A (10) and a layer C (30). The layer A (10) is configured of Ti1-xaMaxaC1-yaNya (wherein Ma is composed of one or more elements selected from among Cr, Nb and W; xa satisfies 0 = xa = 0.7; and ya satisfies 0 = ya = 1). The layer C (30) is configured of Al1-(xc+yc)CrxcMcycN (wherein Mc is composed of one or more elements selected from among Ti, V and Si; xc satisfies 0.2 = xc = 0.8; yc satisfies 0 = yc = 0.6; and (xc + yc) satisfies 0.2 = (xc + yc) = 0.8). The layer A (10) is formed as the outermost surface (S1) of the coating film (100), or formed between the outermost surface (S1) of the coating film (100) and the layer C (30). The distance (d) between the outermost surface (S1) of the coating film (100) and the upper surface (S2) of the layer C (30) is from 0.1 µm to 1.0 µm (inclusive).
