Superabrasive compacts and methods of making superabrasive compacts are disclosed. A superabrasive compact includes a polycrystalline diamond table and a substrate attached to the polycrystalline diamond table. The substrate includes a hard metal carbide and a binder having a compound with a composition of ABC, where A and B are transition metals, where C is carbon, and where 0&#x2264;x&#x2264;7, 0&#x2264;y&#x2264;7, x+y=7, and 0&#x2264;z&#x2264;3.

Cutters comprising polycrystalline diamond attached to a hard metal carbide substrate

The invention is a low binder, wear resistant material including, in weight percent of raw materials, from 15% to 20% of molybdenum carbide added in either elemental or compound form, an alloy of 0.9% to 3% cobalt, nickel or a combination of cobalt and nickel, of 0 to 0.1% of chromium carbide, optionally also titanium carbide or titanium tungsten carbide and the balance of tungsten carbide.
