Down-The-Hole drilling

The Down-The-Hole method (DTH) are easy to opreate and maintain.The method offers a reliable way to drill hard to soft, solid to fissured

or fracture rock, and features a hammer piston, which strikes the drill bit with virtually no power loss. The tubes are smooth and flush along

the entire length of the drill string, minimizing the risk for jamming while ensuring efficient hole cleaning in almost all rock conditions.
