Abstract

An improved sintered compact for use in a cutting tool is proposed which comprises 80 to 95 volume % of high pressure form boron nitride, a binder material which is a carbide, a nitride and/or a carbonitride of a IVb and Vb transition metal in the periodic table, and aluminum compounds. It may further include copper and/or iron group metal or metals. The sintered compact obtained has high hardness even though the sintering pressure and temperature are relatively low.
