| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. presents a versatile array of bit face shapes, each tailored to meet the specific challenges of various rock formations and drilling conditions:
Ideal for achieving superior penetration rates in soft to medium-hard, fissured rock formations. This bit excels under low to medium air pressures, ensuring optimal hole deviation control.
Expertly crafted for versatile applications in medium-hard, homogeneous rock formations, the concave face bit offers excellent hole deviation control and superb flushing capacity.
The convex face bit is engineered for high penetration rates in soft to medium-hard formations under low to medium air pressures. Its design mitigates steel wash, reducing stress and wear on gauge buttons, though it may exhibit limited hole deviation control.
The flat face bit is the choice for hard to very hard, abrasive rock formations requiring high air pressures. It provides impressive penetration rates and excellent resistance to steel wash.
