With identical simulated drilling load applied to both cutters, the previous-generation PDC technology shows high tensile stress near the interface. In contrast, FireStorm technology displays a significant reduction in stress near the interface.

Minimizing the residual stress at the interface of the polycrystalline diamond table and tungsten carbide substrate is key to improving impact resistance. Along with optimized selection of materials and a HPHT polycrystalline sintering process, the engineered tungsten carbide substrate with improved residual stress allows for FireStorm technology’s enhanced capabilities.
