Super Jaws® Overburden Bits: Numa’s Super Jaws Bits provide the best method for simultaneously drilling and casing 5½” to 48” (139 – 1219 mm) holes in hard rock and unconsolidated ground conditions of overburden, boulders, or bedrock. With its unique design, Super Jaws utilizes wings that extend out to drill a full diameter hole while in the drilling position. Upon completion of drilling, the wings retract back into the guide body for extraction of all tooling to the surface while leaving the casing in place. There is no reverse rotation required, nor any expensive rings left in the hole, which saves drillers time and money in applications around the world.
Pole Drills: The company’s Utility Pole Rock Drills offer a complete solution for installation of pole sockets when drilling rock, overburden, boulders, or bedrock. Built for dependable rock drilling and fast penetration rates, Numa’s pole drilling products allow utility contractors to drill 11⅞” to 36” (302 to 914 mm) diameter holes more quickly than traditional auger drilling or blasting methods.
Casing Ring Bits: Numa’s Casing Ring Bits are used for simultaneously drilling and casing vertical or horizontal holes in piling, foundation, anchoring, geothermal, and other casing applications. The system consists of a pilot bit, casing shoe, and heavy-duty ring bit and is available in a wide range of sizes for drilling holes 16″ to 48″ (406 – 1219 mm) in diameter. Options are available for both drill through and non-drill through applications requiring the installation of casing into bedrock. It is a complementary product to Numa’s highly successful Super Jaws® Overburden Bits and Impact Ring Bit Systems®.
