Abstract
A cutting insert may include a base member. The base member may include a first surface, a second surface adjacent to the first surface, and a first cutting edge located in at least a part of a first ridge line which the first surface intersects with the second surface. The base member may include a hard phase containing a titanium carbonitride, and a binding phase containing at least one of cobalt and nickel. The hard phase may include a first hard phase observed on a higher angle side, and a second hard phase observed on a lower angle side in a comparison of () plane peak in an X-ray diffraction analysis. A compressive residual stress of the second hard phase in the second surface may be less than a compressive residual stress of the second hard phase in the first surface.
