12¼" (311.1 mm) PDC diamond bit with 5 blades

A PDC bit is a highly efficient rock-cutting tool used in modern drilling. It combines the high toughness of a carbide (hardmetal) base with the exceptional hardness and wear resistance of a diamond layer, enabling fast and consistent drilling in fields such as oil and gas drilling, geological exploration, geothermal energy, and horizontal directional drilling (HDD).
