ABSTRACT:
A cutting element for a rotary drill bit comprises a thin superhard table of polycrystalline diamond material, defining a front cutting face, bonded to a less hard substrate. The substrate is formed from a material containing at least a proportion of tungsten metal. The substrate may be formed of a metal matrix composite comprising tungsten metal particles in a metal binder phase comprising material selected from: Cu, Co, Ni+Cu, Ni+Fe, Ni+Fe+Mo, Co+Ni. The substrate may also include tungsten carbide in which case the tungsten metal may be replaced by another softer refractory material.
