This aggressive matrix and steel-body bi-center bits is designed for hole opening which provide
maximum drilling efficiency and durability, lower torque, reduced vibration, directionally responsive bit
with a lower cost per foot . Whether drilling float equipment
or formation, it can reduce torque
response, maintain tangents and reduce sliding time without
compromising efficiency.
It features a strong, one-piece construction and a low overall height that enhances directional capabilities
when drilling with down hole motors.Vibration is controlled by
force and mass balancing, employment of spiral
blades and gauge,asymmetrical blade layout,. Because of the
resulting bit vibration control,bit rotation is
maintained about the true bit axis,ensuring accurate finished hole
diameter and quality . Hydraulic ports are
positioned to provide efficient cuttings removal and cleaning of
both the pilot and reaming sections .
A unique gauge profile prevents cutters from contacting and damaging the casing and also provides a
high degree of stabilization and gauge protection. dual-diameter drift and drill bi-center bits have achieved
success in a broad range of applications.
