Replacement Type Cones / Replacement Roller Cone Bit Feature 

HDD&Rotary Core drillers always buy new or used roller cones or hole openers to drill hard rocks.
But the quality of used / second-hand roller cones & hole openers are not stable, though the price is low.

The quality of traditional NEW roller cones & hole openers are stable, but price is always high comparing with project budget. 
The traditional roller cones are produced for tricone bits which is for drilling deep oil / gas well drilling, it is vertical well drilling,
 the drilling depth are always more than 2000 meters, it is a high level drilling application. 

Our new roller cones is designed for HDD specially, the shirttail protection is enhanced and stronger than traditional roller cones. 
The Grease Compensating System of traditional roller cones is simplified to lower the raw cost, as the Grease Compensating System
 of traditional roller cones is not requried for HDD,rotary core drilling applications.

So our NEW roller cones is customized and special for HDD and Rotary Core Drilling applications, hope cooperate with you, welcome  inquiry.
