ABSTRACT:
A method of manufacturing a cutter assembly for a rotary drill bit includes the step of bonding to a carrier a cutting element which comprises a thin hard facing layer already bonded to a less hard backing layer, the backing layer having a greater coefficient of thermal expansion than the hard facing layer. In order to compensate for convex deformation of the rear surface of the backing layer, when the cutting element is heated during the bonding process, the rear surface is made initially concave at ambient temperature. Alternatively, or additionally, the co-operating surface of the carrier may be concave.
