High pressure down-the-hole drill rigs

Sandvik high-pressure down-the-hole (DTH) drill rigs offer a unique combination of high pressure (34.5 bar, 500 psi) and operational flexibility – a powerful match that delivers industry-leading penetration rates and maximum productivity. Our DTH drill rigs are tested around the world and they have proven themselves leaders in pre-split and boom-mounted production drilling. Some models also offer reverse circulation (RC) for in-pit grade control.

The superior performance of Sandvik high-pressure down-the-hole (DTH) drill rigs is powered by diesel-driven compressors controlled with a dual setting system that allows either an increased air flow rate or high pressure as required by the application at hand. These heavy-duty machines can deliver maximum penetration rates both at high altitudes and in extreme cold.
