| General Introduction |
At Changsha Tianhe Drilling Tools and Machinery Co., Ltd., we offer an impressive array of bit face shapes, each engineered to master diverse rock formations and drilling environments:
Perfect for attaining impressive penetration rates in soft to medium hard and fissured rock formations. This bit thrives under low to medium air pressures, ensuring optimal hole deviation control.
Specially designed for versatile applications, this bit excels in medium hard and homogeneous rock formations, offering superb hole deviation control and an enhanced flushing capacity.
Our convex face bit is tailored for rapid penetration in soft to medium-hard formations, compatible with low to medium air pressures. It effectively withstands steel wash, easing the load and minimizing wear on gauge buttons, with a trade-off in hole deviation control.
The flat face bit is engineered for toughness, perfect for hard to very hard and abrasive rocks, operating under high air pressures. It guarantees robust penetration rates and resilience against steel wash.
