Thompson, CT USA - Numa, a leading designer and manufacturer of down hole hammers and bits, has announced a new small diameter bit design that has dramatically improved drilling performance in many different applications around the globe. This enhanced bit design is engineered to handle a wide range of drilling conditions and is perfectly suited for drilling conducted in the water well, construction, mining, quarry, oil & gas and exploration industries.

Numa's engineers have totally redesigned the configuration of Numa's 3", 4", 5" & 6" (76 - 152 mm) bit classes. These improvements incorporate deeper scallops on the face of the bit in conjunction with a strategic repositioning of carbide. The combination of these improvements helps to more efficiently facilitate the removal of cuttings from the hole resulting in increased penetration rates and dramatically improved hole cleaning.

As with all of Numa's products, the new style bits are made from the finest materials under the most exacting conditions. Numa offers these bits in flat, concave and convex face designs to provide the flexibility to drill efficiently in any ground formation. A wide range of standard bit sizes are available in each bit class.

Numa is a major manufacturer of down hole hammers and bits for the international drilling industry. The company designs and builds down hole hammers and bits for drilling vertical and horizontal holes 3-1/2 to 43 inches (89 - 1092 mm) in diameter.
