Bi-center Bit
Bi-center bit for Mining Machinery and abrasive formation
Overview of Bi-center Bit
This type of Bi-center bit mainly used for medium to medium-hard compressive and abrasive formation, it has medium and high-density parabolic crown and heavy cutters density for the bit has good impact resistance and anti-abrasive, high wear-resistant diamond gauge, the bit has a longer service life.
In directional applications, Bi-centredrill bitperformance usually presents perfectin terms of efficiency versus power availability and dynamic issues.
Great Drill Bitsdesigned the bi-center bit to enlarge the wellbore diameter, to replace under reaming, to help control rouble zones and for expandable tubular.

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 increased drilling efficiencies in both vertical and deviated wells.
