THOMPSON, CONNECTICUT USA –
Numa, the world’s leading drilling technology provider, will be exhibiting at IFCEE 2021 on May 10-14, 2021 in Dallas, Texas. Numa will be in outdoor booth 1104 where experts will be on hand to discuss the best methods for drilling rock.
The exhibit will include Numa’s wide range of Made in the USA rock drilling hammers and bits. With over 110 DTH and HDD products, Numa’s leading drilling technology is capable of drilling vertical, horizontal, and reverse circulation holes from 3½ to 50½ inches (89 – 1283 mm) in diameter in hard rock and unconsolidated formations. Numa will hold demonstrations using a cutaway hammer to show how DTH hammers operate.
A special spotlight will be Numa’s Super Jaws Overburden Bits, used for simultaneously drilling and casing 5⅛” to 48” (130 – 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.
Super Jaws is available in two versions, Drive Shoulder and No Drive (ND) Shoulder. The Super Jaws bit with Drive Shoulder utilizes a drive shoe welded to the front of the casing, so the bit and casing advance simultaneously as the Drive Shoulder on the guide body contacts the drive shoe. The Super Jaws ND (No Drive) 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.
