Bit Face Shape Selection
Bit Face Shape Selection
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. proudly presents an exceptional array of bit face shapes, each precisely designed to master various rock formations and drilling scenarios:

An expert choice for achieving rapid penetration in soft to medium-hard and fractured rock formations. This bit excels at low to medium air pressures, precisely maintaining hole deviation for accuracy in drilling.
Concave Face
Crafted for versatile applications in medium-hard and unified rock formations, the concave face bit ensures excellent hole deviation control coupled with superior flushing capability.
Convex Face
The convex face bit shines with high penetration rates in soft to medium-hard terrains, optimized for low to medium air pressures. It resists steel wash and minimizes wear on gauge buttons, though it may offer limited hole deviation control.
Flat Face
The flat face bit is purpose-built for high performance in hard to extremely hard and abrasive rock formations under high air pressures, delivering impressive penetration rates and resistance to steel wash.
Features:
- Exceptional reliability and extended service life, with minimal incidents of abnormal breakage during use.
