casing systems. Compared to conventional air-powered DTH hammers or
top hammers, water-powered DTH hammers offer a wide range of
advantages, including low energy consumption, a cleaner
environment, minimal hole deviation, deeper drilling capabilities,
a high power output ratio and minimal impact on the surrounding
ground.

Product features
1. good sealing effect to prevent water and rock cutting entering
to the hammer
2. high impact power
3. improved hole straightness.
4. Capable to withstand solids content in drilling fluids.
5. reliable performance in challenging ground conditions.
6. Simple design of the piston. Long life.
Deliver maximum energy to drilling bit, which enables fast drilling
speed and low air consumption due to the special inner structure of
the DTH hammer series designed according to the newest rock
drilling theory. Deliver smooth performance and long service of the
DTH hammer series due to the high quality tungsten carbide steel
materials and the advanced processing technology. Low problem rate
and easy maintenance due to the simple, reliable and easy assemble
and disassemble inner structure of hammer.
Application
Sollroc offers a wide range of high performing drilling equipment
designed for percussive drilling. In fact, we offer the most
productive DTH hammers in the world. DTH drilling as a method is
growing in popularity in both foundation works and in well and
geothermal drilling. As the global redevelopment of urban areas
continues, this trend comes with a challenge - accessing and
drilling in populated areas without damaging the existing
structures around the work site. It is obvious that our customers
in geotechnical operations have very different demands on the
equipment than those working with high production drilling in, for
example, quarrying. The demand for application-tailored solutions
is increasing.
