Abstract
An abrasive body which comprises a cubic boron nitride compact bonded to a substrate. The compact has intergrowth between the cubic boron nitride particles which provides it with good thermal conductivity and has major surfaces on each of opposite sides, the one surface being bonded to the substrate and the other surface presenting a cutting edge. The substrate has a coefficient of thermal conductivity at least four times lower than that of the compact. The substrate is preferably made of aluminium oxide, Syalon or zirconia.
