Fight side-tracking while reaming with these off-set designed bits that help guide wellbore enlargement with greater confidence.
Run under-gauge and below a hole opener, the Z-Bit rolls and cuts its way through the wellbore in a way that makes it easier for the hole opener to bring the pilot hole out to proper spec. By flushing through the center of the cone, and utilizing a special nozzle in the shank above the cutter, the Z-Bit’s teeth are kept free of debris for continuous cutting.
