FAQ

1. The Quality of Drill bit?

 

We have many series of rock bits, quality grades are different, and prices are different.

We believe, the proper tools with higher cost-performance is the most important. For example,

our top quality rock bits is not cost-effective for water well driling, as the water well drilling machine

can not drive the super rock bit to perform their best. But for very deep well drilling, high quality grades 

rock bits is cost effective even its price is much higher.

So it is better tell us as more as possible the details of projects, then we provide the proper solutions
