Numa Super Jaws T215ND Duplex Drilling Process

Numa’s Super Jaws® Overburden Bits deliver unmatched performance for simultaneous drilling and casing in overburden and other applications with concern for potential hole collapse. Super Jaws has wings that extend out beyond casing to drill a full diameter hole. Upon completion, the wings retract and all tooling returns to the surface while leaving the casing in place. No expensive tools are left down the hole and no starter casing teeth are required, saving time and money.
The Super Jaws ND version uses a thick wall casing or thick wall threaded casing. The guide body has no drive shoulder and the casing is advanced via a casing hammer, duplex diverter, or dual rotary.
