Applications
- Geotechnical drilling
Highlights
High-performance percussive drilling equipment, including down-the-hole (DTH) and reverse circulation (RC) systems, designed to maximize energy transfer to the bit. They operate efficiently across a range of pressures and are available in multiple configurations covering drilling diameters from 3" to 38".
