Superabrasive tool with metal mesh stress stabilizer between superabrasive and substrate layers

A multi-layer polycrystalline superabrasive blank for attachment to a working tool, said blank comprising:

• (a) a tungsten carbide support substrate layer containing cobalt;
• (b) a superabrasive polycrystalline working layer adjacent the support substrate layer and having an interface between the superabrasive polycrystalline working layer and the support substrate layer, and
• (c) a metal mesh stress stabilizer layer sintered at the interface between and bonded to said support substrate layer and superabrasive polycrystalline working layer, said metal mesh stress stabilizer layer including apertures and wherein the superabrasive polycrystalline working layer has a working layer thickness measured along a normal to the interface between an outermost working layer surface and the interface and the metal mesh stress stabilizer layer has a stabilizer thickness measured along the normal to the interface between a topmost metal mesh stress stabilizer surface and the interface wherein the stabilizer thickness is 5% to 60% of the corresponding adjacent working layer thickness of the superabrasive polycrystalline working layer.
