Numa, the world’s leading drilling technology provider, will be attending CONEXPO-CON/AGG 2017 taking place in Las Vegas, Nevada March  7 – 11, 2017. Numa will be located in Central Hall 3-5 Booth C31610 with experienced staff on hand to meet with current and prospective customers and partners.

Numa will display a full range of DTH hammers and bits for drilling holes 3-1/2” to 48” (89 – 1219 mm) in diameter.  Numa’s DTH products have proven to outdistance competitive hammers and bits in speed and longevity with each model designed for specific types of applications. This gives drillers the ultimate flexibility in product offering. A cutaway hammer will be on hand to provide attendees with the ability to see internal DTH hammer components and how it operates down the hole.

Also exhibited will be Numa’s Super Jaws® Overburden Bits. Super Jaws provides dependable performance and longevity for simultaneously drilling and casing holes in unconsolidated ground conditions of overburden, boulders, or bedrock. With its unique wing design, Super Jaws retracts back into the guide body when drilling is complete for extraction of all tooling while leaving the casing in place. There is no reverse rotation required, nor any expensive rings, saving drillers time and money. Super Jaws is capable of drilling hole sizes 5 ½” to 42” (139 – 1067 mm) in diameter.

Super Jaws is available in two versions. 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 Super Jaws ND 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.
