Abstract
A cBN sinter comprising cubic boron nitride grains and a binder phase, the binder phase comprising Ti2CN and Co2B, wherein the ratio ITi2CN/ICo2B of a peak intensity ITi2CN assigned to Ti2CN appearing at 2θ=41.9° to 42.2° to a peak intensity ITiAl3 assigned to Co2B appearing at 2θ=45.7° to 45.9° is in a range of 0.5 and 2.0 in an XRD measurement.
