INSERT AND CUTTING TOOL
A transmission X-ray diffraction on a cross section of a boron nitride sintered body perpendicular to a first surface provides X-ray intensities at a top of a 111 diffraction peak of cubic boron nitride and X-ray intensities at a top of a 002 diffraction peak of compressed boron nitride, in a direction perpendicular to the first surface and a direction parallel to the first surface. A compressed boron nitride content value obtained from these X-ray intensities is greater than 0.002 and smaller than 0.01. A cubic orientation value is greater than 0.5, and a compressed boron nitride orientation value is greater than the cubic orientation value. An insert has a coating layer on at least a part of a surface of the boron nitride sintered body.
