Beschreibung
Zusammenfassung:	The surface-coated cBN sintered material of the present invention includes a cBN sintered material, and a coating covering the surface of the cBN sintered material. The cBN sintered material contains cBN particles and a binder. A proportion of the cBN particles in the cBN sintered material is exceeding 80% by volume and less than or equal to 98% by volume, the binder contains a first compound including at least one element of Al and Cr and at least one element selected from the group consisting of N, B and O. The coating contains a layer A in contact with the cBN sintered material. The layer A is constituted of Al x1 Cr y1 M z1 C a1 N b1 O c1 (provided that M is greater than or equal to one kind of Ti, V, Nb and Si, and 0.25 ¤ x1 ¤ 0.75, 0.25 ¤ y1 ¤ 0.75, 0 ¤ z1 ¤ 0.5, x1 + y1 + z1 = 1, 0 ¤ a1 ¤ 0.5, 0.5 ¤ b1 ¤1, 0 ¤ c1 ¤ 0.1, and a1 + b1 + c1 = 1 are satisfied).
