Abstract:
In this novel PDC cutter, diamond powders of different composition and/or different grain size, are distributed, shaped, and compacted with a novel pressing tool, in multiple stages, spatially arranged into different regions of the PDC diamond body, then HPHT sintered to form one PDC body with spatially varying hardness, toughness and thermal resistance.
