This Ingersoll Rand DMLSP is a used vertical drill, a type of machine also known as a blast hole drill, designed for rotary or down-the-hole percussion drilling in mining, quarrying, and construction applications. Ingersoll Rand is a long-established industrial manufacturer with a significant heritage in compressed air equipment, drilling machinery, and ground-engaging tools, and their drill rigs are widely used in surface mining and aggregate production.
This particular machine is configured as a DTH-class rig, meaning it is equipped for down-the-hole hammer drilling, where the percussive action occurs at the drill bit rather than at the surface, allowing for efficient penetration in hard rock formations. The single-pass mast has a capacity of 55 to 60 feet, enabling the rig to drill that depth in a single pass without the need to add drill pipe extensions, which improves cycle time and operational efficiency on a bench.
Power comes from a Cummins QSK19 diesel engine, a large-displacement inline engine in Cummins's heavy-duty K-series line, well suited to the sustained high-load demands of continuous drilling operations. Air supply for the DTH hammer is provided by an onboard Ingersoll Rand HR2.5 high-pressure compressor, rated at 1,050 CFM at 350 PSI. This combination of high flow volume and elevated working pressure is characteristic of rigs intended for serious hard-rock DTH work, where adequate air delivery to the hammer is critical to penetration rate and hole-clearing performance.
The undercarriage is sourced from a Caterpillar 330L&S, a tracked carrier that provides the stability and mobility needed to manoeuvre across the uneven terrain typical of open-pit and quarry environments. The machine is located in Kentucky, USA, and dates from 1997.
