Numa will be exhibiting at the Pacific Northwest Ground Water Exposition taking place March 18-19, 2022 in Portland, Oregon. Numa will be exhibiting in booth #161 with drilling experts on hand to discuss all your rock drilling needs.

Numa’s display will feature Made in the USA water well DTH hammers and bits capable of drilling holes 3 ½” to 24” (89 – 610 mm) in diameter. Able to drill at high frequency, dependable Patriot hammers and bits require less air resulting in smoother operation and efficient drilling. Even against high heads of water.

Numa will also highlight its Super Jaws® Overburden Bits for simultaneously drilling and casing 5½” to 48” (139 – 1219 mm) holes. Super Jaws has wings that extend out to drill a full diameter hole. Upon completion, the wings retract and all tooling returns to the surface while leaving the casing in place. No expensive tools are left down the hole and no starter casing teeth are required, saving drillers time and money.
