Abstract:
A sintered material includes cubic boron nitride grains and a binder, a grain size D50 of the cubic boron nitride grains when a cumulative value of the cubic boron nitride grains is 50% in an area-based grain size distribution being more than 0.5 μm and less than or equal to 5 μm, more than or equal to 70 volume % and less than or equal to 98 volume % of the cubic boron nitride grains being included in the sintered material, the binder being composed of A1-xCrxN, where 0≤x≤1, and a remainder, the remainder being composed of at least one of a first element and a compound including the first element and a second element, the first element being one or more elements selected from a group consisting of W, Co, Ni, Mo, Al, and Cr, the second element being one or more elements selected from a group consisting of nitrogen, carbon, oxygen, and boron.
