Insert and cutting tool
A blade (1) according to the present invention has a cBN sintered body in which a plurality of cBN particles (11) are bonded via a binder phase (12). In a cross section of the cBN sintered body, the cBN particles (11) account for 60% by area or more. In addition, the binder phase (12) contains Al compound particles, and the Al compound particles contain at least one of AlN and Al2O3. Furthermore, the particle size distribution of the Al compound particles in the cross section of the cBN sintered body is such that the proportion of Al compound particles having a particle size of 0.3 [mu] m or more is 5% or more and the proportion of Al compound particles having a particle size of 0.5 [mu] m or more is less than 5% in the cumulative distribution of the Al compound particles based on the number of the Al compound particles.
本发明的刀片(1)，具有多个cBN粒子(11)经由粘结相(12)结合而成的cBN质烧结体。在cBN质烧结体的截面中，cBN粒子(11)占60面积％以上。另外，粘结相(12)含有Al化合物粒子，该Al化合物粒子含有AlN和Al2O3之中至少一方。另外，cBN质烧结体的截面中的Al化合物粒子的粒度分布为，在Al化合物粒子以个数为基准的累积分布中，粒径为0.3μm以上的Al化合物粒子的比例为5％以上，粒径为0.5μm以上的Al化合物粒子的比例低于5％。
