Duo-Bore Bits

The Bestebit Duo-Bore Bit is designed to drill up to 30% larger diameter holes while eliminating the need for under reamers and conventional hole-opening tools. Its one-piece construction enhances directional control, hydraulic efficiency, and stability, ensuring smoother drilling, reduced vibration, and minimal casing damage. With an aggressive cutting structure, optimised blade design, and advanced force balancing, the Duo-Bore Bit delivers higher ROP, improved wellbore quality, and lower overall drilling costs.
