numa dth hammers,
water well drilling hammer
High Pressure DTH hammer DHD380 is very popular in international mining drilling and rock excavation field.
Sollroc produces the most efficient drilling hammers (DTH), built for the most diverse applications: water drilling, construction, mines etc. Our technology and unique design gives to our drilling hammers high performance, in various types of formations.
The valve system of our hammers is essential for efficient DTH drilling: increase the compressed air power delivered to the bit, providing efficient utilization of the air and reducing the service requirements. Our technology minimizes turbulence and backflow, allowing the piston to transfer more energy to the bit and hit the bit harder. That means faster penetration rates and more productivity.

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.
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.
Sollroc , with more 10 years of experience ,is one of the professional manufacturer and supplier of high performance rock drilling tools,We are able to manufacture, export and supply our clients excellent quality DTH Hammers like DTH Hammer Bits and RC Hammer.
