SURFACE-COATED BORON NITRIDE SINTERED BODY TOOL
A surface-coated boron nitride sintered body tool includes a cubic boron nitride sintered body and a coating film (100) formed thereon. The coating film (100) includes an A layer (10) and a C layer (30). The A layer (10) is formed of Ti 1-xa Ma xa C 1-ya N ya (where Ma is one or more ofCr, Nb and W; xa is 0 ¤ xa ¤ 0.7; and ya is 0 ¤ ya ¤ 1). The C layer (30) is formed of Al 1-(xc + yc )Cr xc Mc yc N (where Mc is one or more of Ti, V and Si; xc is 0.2 ¤ xc ¤ 0.8; yc is 0 ¤ yc ¤ 0.6; and xc + yc is 0.2 ¤ xc + yc ¤ 0.8). The A layer (10) is formed on an outermost surface (S1) of the coating film (100) or between the outermost surface (S1) of the coating film (100) and the C layer (30). A distance (d) between the outermost surface (S1) of the coating film (100) and an upper surface (S2) of the C layer (30) is 0.1 µm or more and 1.0 µm or less.
