Numa Exhibiting at bauma 2022

September 21, 2022


Numa, the world’s leading drilling technology provider, will be exhibiting at bauma 2022, the 33rd edition of the world’s largest trade fair taking place in Munich, Germany October 24 – 30. Numa will be exhibiting in Hall C4.539 of the USA Pavilion with drilling experts on hand to discuss any drilling needs.

The company’s stand will showcase a full line of Made in the USA rock drilling hammers and bits, capable of drilling in a wide range of rock formations and conditions. A special spotlight will be on their Super Jaws Overburden Bits used 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.

The company will also feature its Casing Ring Bit Systems 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 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®.
