The Advantage of Bi-center Bit

Our Bi-center bit is one piece body, you will never worry broken.

We can adjust the bi-center diameter according to your casing diameter. Generally speaking, the bigger pilot bit has smaller reaming size. The smaller pilot bit has a bigger reaming size.

GREAT's casing protection features cutting structure that provides a reliable way to drill, protecting both the cutting structure inside the casing and the casing itself.

During the design process, the pilot and reamer cutting structure are force balanced as a single unit. This provides the bi center drill bits increased drilling efficiencies in both vertical and deviated wells.

If you have any doubt on that ,just feel free contact with us ,we will have future explain and provided drawing.
