Numa is the world’s leading drilling technology provider, with the highest value in products, performance and service in the entire drilling industry.

Our hammers feature a simplified design that incorporates only eight (8) major parts. Included is a feed tube assembly that attaches directly to the backhead of the hammer to provide outstanding alignment of all hammer parts.  Better alignment and less overall parts makes Numa hammers not only perform better but are easier to maintain than competitors, which means more time drilling and reduced drilling cost.

Many drillers also find our Super Jaws® Overburden Bits deliver dependable performance and longevity for drilling dewatering holes in unconsolidated ground conditions of overburden, backfill or bedrock. Super Jaws produces unmatched penetration rates for simultaneously drilling and casing holes. With its unique wing design, Super Jaws retracts back into the guide body 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 in mining and quarry applications.
