| General Introduction |
At Changsha Tianhe Drilling Tools and Machinery Co., Ltd., we present a diverse array of bit face shapes, meticulously designed to cater to various rock formations and drilling scenarios:
This bit is your go-to choice for high penetration rates in soft to medium hard, fissured rock formations. Ideal for low to medium air pressures, it ensures optimal control over hole deviation.
Versatile and efficient, the concave face bit is crafted for medium hard, homogeneous rock formations. It offers excellent hole deviation control and superior flushing capacity, making it an all-around performer.
The convex face bit is engineered for rapid penetration in soft to medium-hard formations under low to medium air pressures. It boasts resistance to steel wash, minimizing load and wear on gauge buttons, albeit with potentially limited hole deviation control.
For the toughest challenges in hard, very hard, and abrasive rock formations under high air pressures, the flat face bit excels. It promises commendable penetration rates and strong resistance to steel wash.
Choose Changsha Tianhe Drilling Tools and Machinery Co., Ltd. for superior drilling bits that offer unparalleled performance and longevity.
