| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. is proud to offer a remarkable variety of bit face shapes, each carefully crafted to master a range of rock formations and drilling conditions:
This bit is an exceptional choice for rapid penetration in soft to medium-hard and fractured rock formations. It performs optimally at low to medium air pressures, ensuring precise hole deviation for accurate drilling.
Designed for a wide array of applications in medium-hard and homogeneous rock formations, the concave face bit delivers excellent hole deviation control and superior flushing capacity.
The convex face bit is renowned for high penetration rates in soft to medium-hard terrains, optimized for low to medium air pressures. It offers resistance to steel wash and reduces wear on gauge buttons, although it may provide limited hole deviation control.
The flat face bit is engineered for outstanding performance in hard to extremely hard and abrasive rock formations under high air pressures, offering impressive penetration rates and resistance to steel wash.
