| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. provides an extensive array of bit face shapes, each designed to optimize performance across various rock formations and drilling conditions:
Optimized for rapid penetration in soft to medium-hard and fissured rock formations, this bit excels under low to medium air pressures, offering superior control over hole deviation.
Engineered for versatile use in medium-hard and uniform rock formations, the concave face bit ensures excellent control of hole deviation and effective flushing capacity.
The convex face bit is adept at achieving high penetration rates in soft to medium-hard formations under low to medium air pressures. It effectively resists steel wash and minimizes load and wear on gauge buttons, though it may show reduced hole deviation control.
Tailored for hard to extremely hard and abrasive rock formations, the flat face bit demonstrates superb penetration rates and robust resistance to steel wash, supported by high air pressures.
Opt for Changsha Tianhe Drilling Tools and Machinery Co., Ltd. for superior drilling bits, promising unmatched performance and longevity.
