1. The crown surface of the drill bit is a long cast surface, covered by double rows of cutters, which increases the stability of the drill bit when drilling at high speed. This bit is suitable for abrasive formations.
2. The shoulder is subject to complex stress and serious wear. Therefore, we enhanced the local design to maximize the equal yield density and wear resistance of the tool.
3. The drill bit is designed with 3 blades, and the flow is wide to prevent the drill bit from pilling. Blades are designed to be asymmetric one to eliminate unbalanced forces and reduce damage to the tool.
4. The gauge surface is designed in a spiral shape to increase the density of teeth and reduce the length of the effective gauge diameter. This design can increase the measuring area, reduce the torque, and increase the life of the drill. At the same time, the drill can be better controlled by the nozzle. The double-row PDC knife gauge teeth are embedded/inlaid with the long gauge surface to enhance wear resistance and gauge effect. It also increases bit stability.
