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.
