DHD350 / COP54 Blue Color Dth Hammer For Dimensional Stone Industry
DHD350/COP54 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 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.
