DOWN-THE-HOLE HAMMERS
DTH(Down the Hole) 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.
Roschen DTH hammers transmit intensive impact energy with low
energy loss. This results in good rock breakage, high penetration
rates and high productivity. The equipment is designed to give
optimal hole quality, reliability, and long service life, as well
as the best blasting results and low total operation cost.
Roschen hammers are flexible, and designed to work with various
industry-standard shank designs and a wide range of standard size
hammers. Whatever your application, Roschen has the solution to
match your requirements.
