| General Introduction |
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. provides an array of bit face shapes, meticulously designed to adapt to diverse rock formations and drilling scenarios:
Perfect for achieving high penetration rates in soft to medium-hard and fissured rock formations. This bit is ideal for operations with low to medium air pressures and excels in delivering maximum hole deviation control.
Crafted for versatile use in medium-hard and homogeneous rock environments, the concave face bit ensures excellent hole deviation control and enhanced flushing capacity.
The convex face bit is designed for high penetration rates in soft to medium-hard formations under low to medium air pressures. It effectively resists steel wash, reducing the load and wear on gauge buttons, though it may offer limited hole deviation control.
Specifically suited for hard to very hard, abrasive rock formations with high air pressures. This bit provides robust penetration rates and superior resistance to steel wash.
Select Changsha Tianhe Drilling Tools and Machinery Co., Ltd. for premium drilling bits that offer remarkable performance and longevity.
