High pressure down-the-hole drill rigs

Sandvik 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.

Our Sandvik DR580 is a diesel-powered, high-pressure down-the-hole (DTH) drill rig that delivers the highest air pressures and air flow rates compared with any boom DTH drill. It drills blast holes with a diameter of 115 - 216 millimeters (4 ½ - ½ inches) down to a maximum depth of up to 54.9 meters (180 feet). This heavy-duty mining machine delivers maximum penetration rates and excels at high altitudes.

Our Sandvik DR560 is diesel-powered, high-pressure down-the-hole (DTH) drill rig equipped with an up to 34.5 bar (500 psi) compressor. It drills holes with a diameter of 115 - 216 millimeters (4 ½ - ½ inches) down to a maximum depth of up to 54.9 meters (180 feet). The large air volume enables both pre-split and production drilling, and the heavy-duty structure allows for an optional RC package for in-pit grade control.

Sandvik DR540 Down the hole drill rig

Our Sandvik DR540 high-pressure down-the-hole (DTH) drill delivers leading penetration with an up to 34.5 bar (500 psi) compressor. The large air volumes deliver performance in pre-split and production drilling, and the heavy-duty structure allows for optional RC package for in-pit grade control. It drills blast holes with a diameter of 115 - 203 millimeters (4 ½ - 8 inches).
