Abstract
An insert of the present disclosure includes a cBN sintered compact containing cBN and TiN. The cBN occupies 60% or more of the cross-sectional area of the cBN sintered compact observed. TiN (200) is higher than cBN (111), where the TiN (200) is an X-ray intensity on a (200) plane of the TiN and the cBN (111) is an X-ray intensity on a (111) plane of the cBN, obtained by X-ray diffraction on the cBN sintered compact.
