Down The Hole Hammers (DTH) Hammer
 
Roschen produces Geothermal Drills, (DTH) Down The Hole Rock Hammers, (HDH) Horizontal Directional Hammers, Bits, and Hammer Replacement Parts for these industries: geothermal, gas, oil, mining, construction, quarries, and water well. 
Roschen name stands for superior quality, performance, service and value. All of our DTH hammers are made in America. Don't be held hostage to foreign manufacturers' inferior hammers that require special bits not always readily available.
DOWN THE HOLE DRILLING HAMMERS
DTH hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling.
Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.
Roschen offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method.
