Product Description

 General Introduction

Product Description

Changsha Tianhe Drilling Tools and Machinery Co., Ltd.

Product Description

• Features:




• Reliable quality and long service life with rare abnormal breakage during service life.


• Good flushing effect ensures high drilling rate.


• Strict quality warranty and compensation rules.


• Reasonable designs.


• High penetration.




• Bit Face Shape Selection:




• Drop Center Bit: For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.


• Concave Face: The all-around application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.


• Convex Face: For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistant to steel wash and may reduce the load and wear on the gauge buttons, but poor hole deviation control.


• Flat Face: This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash.
