SURFACE-COATED BORON NITRIDE SINTERED TOOL
표면 피복 질화붕소 소결체 공구는, 적어도 절삭날 부분이 입방정 질화붕소 소결체와 그 입방정 질화붕소 소결체의 표면 상에 형성된 피막을 구비하고, 그 피막은 Si를 함유하고, 조성이 상이한 B1 화합물층과 B2 화합물층이 교대로 각각 하나 이상 적층되어 이루어진 B층을 포함하고, 그 B1 화합물층의 평균 두께 t1과 그 B2 화합물층의 평균 두께 t2의 비인 t2/t1이 0.5
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 contains Si and includes a B layer formed by alternately stacking one or more of each of a B1 compound layer and a B2 compound layer that are different in composition. A ratio between an average thickness t 1 of the B 1 compound layers and an average thickness t2 of the B2 compound layers is defined as t2/t1 that satisfies a relation of 0.5 < t2/t1 ¤ 10
