SURFACE-COATED BORON NITRIDE SINTERED TOOL
A surface-coated boron nitride sintered body tool is provided, in which at least a cutting edge portion includes a cubic boron nitride sintered body and a coating film formed on a surface of the cubic boron nitride sintered body. The coating film includes an A layer, a B layer and a C layer The C layer is provided between the A layer and the B layer. The A layer contains Ti and the like The B layer is formed by alternately stacking a B compound layer containing Ti, Si and the like and a B2 compound layer containing Al and the like The C layer includes McLc zc (Mc represents one or more of group 4 elements, group 5 elements and group 6 elements in a periodic table, Al and Si; Lc represents one or more of B, C, N, and O; and zc is more than 0 and 0.85 or less).
