The PDC Arc bit represents a recent advancement in high-end drill technology. Its design concept draws inspiration from petroleum drilling applications and is primarily employed for gas extraction, water exploration and release, grouting drilling, and various other drilling construction purposes.

The four-winged arc bit is specifically engineered for challenging hard formations. In comparison to conventional recessed bits, the four-winged arc bit exhibits a remarkable increase in its operational lifespan, exceeding threefold, all while maintaining a consistent drilling footage rate. This is particularly advantageous when dealing with complex formation conditions characterized by sulfur-nodules, fragmentation, extensive fissures, and pronounced abrasiveness, where the bit consistently delivers outstanding performance.

On the other hand, the three-blade arc bit is tailored for use in soft and medium-hard formations. With a focus on optimizing both bit life and drilling speed, it significantly reduces drilling time, thereby substantially enhancing construction efficiency, especially in the context of medium-hard and soft strata construction projects.
