THOMPSON, CONNECTICUT USA –
Numa, the world’s leading drilling technology provider, will be exhibiting at DFI SuperPile ‘18 happening June 27 to 29, 2018 in New York City. Numa will be located in booth 202 where DTH experts will be on hand to discuss products best suited for drilling displacement piles, drilled shafts, helical piles, tiebacks, marine foundations, and micro piles.
DFI member, Numa, has earned the reputation as an innovator for piling and foundation drilling equipment and offers one of the largest ranges of DTH hammers and bits. With over 110 DTH products, Numa has the equipment and expertise to assist contractors drilling vertical, horizontal, and reverse circulation holes from 3½ to 50½ inches (89 – 1283 mm) in diameter in hard rock and unconsolidated formations.
Showcased at SuperPile ’18 will be Numa’s Super Jaws® Overburden Bits. Super Jaws is one of the best methods for simultaneously drilling and casing holes in unconsolidated ground conditions of overburden, boulders, or bedrock. The bits utilize a unique design where wings extend out larger in diameter than the casing while in the drilling position. When drilling is completed, the bit is simply lifted off bottom, causing the wings to retract back into the guide body and all tooling can be brought back to the surface while leaving the casing in place. There is no reverse rotation required, nor any expensive rings left in the hole saving drillers time and money. Super Jaws is capable of drilling hole sizes 5 ½” to 42” (139 – 1067 mm).
Numa offers two versions of the Super Jaws Overburden Bits. One version utilizes a drive shoe welded to the front of the casing. As the bit advances, the casing is advanced at the same rate due to the drive shoulder on the guide body contacting the drive shoe welded to the casing. The second version is Super Jaws ND. The ND (No Drive Shoe) version allows the use of 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.
