Numa is the world’s leading designer, manufacturer, and US provider of drilling equipment with the best rock drilling hammers and horizontal drilling equipment for drilling holes from 3½ – 50½ inches (89 – 1283mm) in diameter
Down the hole hammers, usually called DTH hammers, is basically a mini jackhammer screwed on the bottom of drill strings. The fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer bits. DTH drills are one of the fastest ways to drill hard rock. It was only when down the hole hammers came along that many of the problems associated with the other systems were overcome – with the DTH system and dth drilling tools, the energy source is constantly behind the drill bit with copious amounts of air passed through the drill string to operate the DTH Hammer which is then used to efficiently flush the bore hole clean.
Numa DTH products and down the hole drills are designed to drill holes in hard rock, overburden, or loose strata formations in many different types of drilling applications. These markets are commonly found in the construction, oil & gas, mining, quarry, geothermal, water well, horizontal and other rock drilling industries. Operators of DTH products and rock drilling equipment drill holes from a few feet to 1000’s of feet deep. In fact, one of the deepest holes on record was drilled to 17,600 feet (5364 m) below the surface. If you are interested in our DTH Hammers, DTH bits, or other products, contact us today.

Horizontal Directional Drilling (HDD) is a method of installing underground pipelines, cables and service conduit through trenchless methods. Our horizontal directional drilling tools are a good fit when you installing infrastructure such as telecommunications and power cable conduits, water lines, sewer lines, gas lines, oil lines, product pipelines, and environmental remediation casings. Our tools are used when crossing waterways, roadways, shore approaches, congested areas, environmentally sensitive areas, and areas where other methods are costlier or not possible.
The equipment used in horizontal drilling depends on the outer diameter of the pipe, length of the run, ground conditions and the surroundings above ground. Horizontal directional drilling is done with the help of a viscous fluid known as drilling fluid. a mixture of water and, usually, bentonite or polymer continuously pumped to the cutting head or drill bit to facilitate the removal of cuttings, stabilize the bore hole, cool the cutting head, and lubricate the passage of the product pipe.
All Numa HDD hammers are constructed Made in the USA, premium steel allowing drillers to use our products longer than competing brands. Furthermore, the single bore design allows for a maximum bore diameter in conjunction with optimum life against abrasion. Quite simply, the Numa HDD product line provides performance and dependability without sacrificing tool life.
