Water-Powered Drilling: The Water Hydraulic DTH Technology

The Wassara technology uses water to power the down-the-hole (DTH) percussion hammer. This makes it the superior choice for many drilling applications where air-powered DTH hammer, top hammer or rotary drilling equipment are normally used.

The mechanised drilling in mining operations started some 140 years ago with the invention of the pneumatic top hammer. Productivity demands have forced development in new technologies, and the possibility to drill long and straight holes gave a huge step in this direction. The most recent major innovation in drilling came with the water-powered DTH hammer from Wassara.
