摘要： A cutting insert has a surface that relates to cutting, the surface comprising cBN sintered material, ceramics, or cermet. The cutting insert comprises: a rake face; a flank face; a chamfer located between the rake face and the flank face; and a cutting edge formed by a ridgeline at which the flank face and the chamfer intersect. The cutting edge comprises a cutting edge portion for push cutting, a cutting edge portion for pull cutting, and a connecting cutting edge portion located between the cutting edge portion for push cutting and the cutting edge portion for pull cutting. In the chamfer located along the cutting edge, the chamfer located along the connecting cutting edge portion has a minimum width.

摘要： A surface-coated cutting tool including a substrate including a rake face and a flank face and a coating which covers a surface of the substrate is provided. The substrate is made of a cBN sintered material or a ceramic sintered material. The coating includes an alternating layer. The alternating layer is made by alternately stacking a first layer and a second layer different in composition from the first layer. The first layer contains Al, Cr, and N. The second layer contains Ti, Al, and N. A ratio T1/T2 between a thickness T1 of the first layer and a thickness T2 of the second layer is not lower than 0.1 and lower than 1. There are thirty or more interfaces at which the first layer and the second layer are in contact with each other.
