At Changsha Tianhe Drilling Tools and Machinery Co., Ltd., we understand the diversity of drilling conditions. That's why we offer an extensive range of bit face shapes, meticulously designed to match various rock formations and drilling environments:
Engineered for excellence in soft to medium hard and fissured rock formations, the Drop Center Bit achieves impressive penetration rates. Ideal for operations with low to medium air pressures, it provides unparalleled control over hole deviation, making it a staple in efficient drilling.
Crafted for versatility, the Concave Face Bit excels in medium hard and homogeneous rock formations. It ensures superb hole deviation control and boasts an impressive flushing capacity, making it a reliable choice for diverse applications.
The Convex Face Bit is designed for high penetration rates in soft to medium-hard formations, performing optimally at low to medium air pressures. Its resistance to steel wash and reduced load on gauge buttons make it a valuable asset, though it may experience limited hole deviation control.
When facing hard to very hard and abrasive rock formations, the Flat Face Bit is your best ally. Tailored for high air pressures, it promises excellent penetration rates and remarkable resistance to steel wash, ensuring longevity and efficiency.
For unmatched performance and durability in drilling bits, choose Changsha Tianhe Drilling Tools and Machinery Co., Ltd. and elevate your drilling experience.
