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 bi center drill bit has a longer service life.

In directional applications, bi center drill bit performance usually presents performance challenges in terms of efficiency versus power availability and dynamic issues.

Cangzhou Great Drill Bits Co.,Ltd. designed the bi-center bit to enlarge the wellbore diameter, to replace under reaming, to help control rouble zones and for expandable tubular. And GREAT provides directional drill bits for sale now, if you want to know more about rock drill bits price and other detailed information , please contact us.

The Specification of Bi-center Bit

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.
