SpeedReamer™ Bits
Description

Our SpeedReamer™ Bi-Center bits allow you to meet the demands of hole opening in small diameter sections. The bits drill and underream in one continuous operation, offering smoother torque response and improved steerability. Hole opening applications improve cement jobs, reduce equivalent circulating density (ECD), and help you avoid casing running problems.
