Compact drill rig for smaller quarries

ConExpo-ConAgg 2011 in Las Vegas in March this year marked the launch in North America of the DI550, the first of Sandvik’s latest generation of down-the-hole (DTH) drill rigs.
The new machine offers productivity and user comfort in 5” hammer drilling, particularly for large and medium sized quarries and contractors in particular. It features a 324 kW diesel engine and a 24.4m3 compressor air flow at 24 bar pressure, ideally making the rig uniquely productive, while keeping fuel consumption and operating costs as low as possible. Cost effective machine performance is further enhanced by other advanced features such as active diesel RPM control, optimised diesel RPM level during drilling and active control of compressor running temperature.

All daily maintenance points around the rig are located on the ground level to simplify the process and improve the safety of service personnel. A fast fuel filling option and large fuel tank further cut costly downtime.


The new DTH line has benefited from Sandvik’s experience in top hammer drilling solutions. To that end, the DI550 is suited to work at its maximum performance with Sandvik’s RH550 hammers from 3” to 5”. The RH550 hammers come with bits from 90mm up to 152mm with three different bit face designs.
