Numa, a leading drilling technology provider, has released a range of Utility Pole Rock Drills that it says offer a complete solution for installation of pole sockets when drilling rock, overburden, boulders or bedrock.

“Numa’s ongoing product innovation and results-oriented consistency have been the lifeblood for Numa for the past 35 years,” says Numa President Ralph Leonard. “Our Utility Pole Rock Drills continue this legacy with a high quality product delivering dependable results across many different applications.”

Numa’s Utility Pole Rock Drills consist of a variety of components, including hammers, bits, swivels, shock subs, adaptors and shrouds, capable of drilling holes 11⅞ to 36 inches (302 to 914 millimeters) in diameter.
