Bi-center Bit

Bi-center bit for Mining Machinery and abrasive formation

Overview of Bi center Bit

This type of bi center drill 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 bicenter drill bit has a longer service life.

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

GREAT designed the bi-center bit to enlarge the wellbore diameter, to replace under reaming, to help control rouble zones and for expandable tubular.

Bi-center Bit Design

We designed this wholesale bi center drill bit with close attention to hydraulic optimization to improve chip removal and ensure effective tool cooling. In addition to the improved hydraulic configuration, the cutting configuration was carefully studied to ensure that it is both effective and balanced – not only on conventional components but also when used in combination with a bent-case motor. This design concept of bi center bits combined with GREAT’s wide range of PDC cutters grades and geometries results in a bi-center drill with excellent drilling performance.

Great Drill Bits is a rock drill bit factory, we have strongest drill bits for sale, rock drill bit, drill bit that makes big holes and etc. Welcome to know more about us.
