Abstract:
A cubic boron nitride sintered material where wear resistance is suppressed from decreasing having excellent chipping resistance and a cutting tool made thereof are provided. The sintered material is constituted from cubic boron nitride particles that are bound by a binder phase, while the binder phase contains a carbide of at least one kind of metal element selected from among metals of groups 4, 5 and 6 of the periodic table and a nitride of at least one kind of metal element selected from among metals of groups 4, 5 and 6 of the periodic table coexisting therein, and therefore the particles can be suppressed from coming off and the binder phase can be suppressed from wearing and coming off at the same time, thereby making the sintered material having high wear resistance and particularly excellent chipping resistance.
