Numa

Numa has worked hard to provide innovative solutions for drillers in all types of drilling industries. They continue to be instrumental in the development of large diameter hammers, introducing models capable of drilling holes up to 43″ (1092 mm). They also lead the industry in reverse circulation and horizontal application hammers and bits.

SUPER JAWS®
OVERBURDEN DRILLING SYSTEMS

Drilling through unconsolidated ground conditions in order to set casing into bedrock is one of the most challenging tasks facing the drilling industry. That is why Numa has spent so much time and energy designing a drill bit that can drill a larger diameter hole than the casing, while simultaneously advancing the casing.

CONVENTIONAL HAMMERS & BITS

Numa offers the largest range of conventional down hole hammers and bits available in the drilling industry today. Unmatched in longevity and penetration rates, these performance driven Patriot®, Champion® and Challenger® hammer models are able to drill holes from 3-1/2″ to 43″ (89 – 1092 mm) in diameter.

NUMA LUBRICATION SYSTEM

Numa’s pneumatic lubricators are positive displacement, air-operated, lubrication systems. They are designed to inject rock drill oil into the air line under positive pressure to ensure the proper amount of oil is supplied to the DTH hammer while drilling.
