| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. provides diverse bit face shapes, ingeniously designed to adapt to various rock formations and drilling scenarios:
Perfectly engineered for high penetration rates in soft to medium-hard and fissured rock landscapes. This bit excels under low to medium air pressures, offering optimal hole deviation control for precise drilling operations.
Tailored for versatile use in medium-hard, uniform rock formations. The concave face bit ensures excellent hole deviation control paired with superior flushing capacity, optimizing drilling performance.
The convex face bit is a powerhouse for high penetration in soft to medium-hard formations with low to medium air pressures. It minimizes steel wash, reducing wear on gauge buttons, though it may compromise on hole deviation control.
The flat face bit is your go-to for hard to extremely hard, abrasive rock terrains under high air pressures, delivering impressive penetration rates and strong resistance to steel wash, ensuring durability.
Opt for Changsha Tianhe Drilling Tools and Machinery Co., Ltd. for unmatched drilling bits that promise exceptional performance and resilience.
