| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. offers an impressive array of bit face shapes, each carefully designed to masterfully tackle various rock formations and drilling conditions:
This strategic choice excels in achieving rapid penetration in soft to medium-hard and fractured rock formations. It performs splendidly at low to medium air pressures, adeptly sustaining hole deviation for precise drilling outcomes.
Crafted for adaptable use in medium-hard and uniform rock formations, the concave face bit delivers excellent hole deviation control paired with outstanding flushing capability.
The convex face bit shines with high penetration rates in soft to medium-hard terrains, optimized for low to medium air pressures. It presents resistance to steel wash and reduces wear on gauge buttons, yet may offer limited hole deviation control.
The flat face bit is designed for peak performance in extremely hard and abrasive rock formations under high air pressures, providing excellent penetration rates and resilience against steel wash.
