Numa Super Jaws Concept

Описание к видео Numa Super Jaws Concept

Details the concept and shows animation of Numa’s Super Jaws Overburden Bits. Super Jaws bits are the perfect choice for simultaneously drilling and casing 5½” to 48” (139 - 1219 mm) holes. The patented design utilizes wings that extend out to drill a full diameter hole. Upon completion, the wings retract and all tooling is brought back to the surface while leaving the casing in place. No expensive tools are left down the hole and no starter casing teeth are required. For dependable performance and longevity, use Numa’s authentic Super Jaws bit.
