| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. provides an expansive selection of bit face shapes, expertly tailored to adapt to a variety of rock formations and drilling circumstances:
This bit is an optimal choice for achieving impressive penetration rates in soft to medium-hard and fissured rock formations. It operates effectively under low to medium air pressures while ensuring superior hole deviation control.
The concave face bit is designed for versatile use in medium-hard and homogeneous rock formations, offering remarkable hole deviation control and efficient flushing capacity.
The convex face bit excels in delivering high penetration rates in soft to medium-hard formations, operating under low to medium air pressures. It minimizes steel wash and reduces load and wear on gauge buttons, although it may exhibit limited hole deviation control.
Ideal for tackling hard to very hard and abrasive rock formations, the flat face bit operates under high air pressures, offering excellent penetration rates and resistance to steel wash.
