Product Description

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-centre drill bit performance usually presents perfect in terms of efficiency versus power availability and dynamic issues.

Great Drill Bits designed 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.
