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 center 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.
