CUBIC BORON NITRIDE SINTERED COMPACT CUTTING TOOL
A cBN sintered material cutting tool includes a cutting tool body that is made of a sintered material including cubic boron nitride particles and a binder phase, in which: an average particle size of the cBN particles is 0.5 µm or less and a content ratio of the cBN particles in the sintered material is 35 vol% to 80 vol%; and the binder phase includes 1.0 vol% to 20 vol% of an Al compound, an average particle size of the Al compound present in the binder phase is 300 nm or less, and a value of a ratio (a value of S N /S O ; area ratio) of a content S N of nitrogen (N) included in the Al compound to a content So of oxygen (O) included in the Al compound is 1.1 to 5.
