Maximize your drilling performance and minimize differential sticking with these heavy-duty Spiral Drill Collars. At 9.375" OD, these collars are engineered for large-diameter hole sections, providing the rigid weight and torque resistance required for demanding formations.

The spiral groove design reduces the surface contact area between the collar and the wellbore, significantly lowering the risk of stuck pipe in high-pressure or permeable zones.
