2003 - Sandvik D55SP Vertical Drill

About this machine

The Sandvik D55SP is a used vertical drill — sometimes referred to as a rotary drill rig or blast hole drill — a type of heavy drilling machine used in surface mining, quarrying, and construction to bore vertical holes into rock and earth, typically for blasting or geotechnical purposes. Sandvik is a well-established Swedish engineering group with a strong global presence in mining and rock excavation equipment, producing machinery that serves hard-rock mining, quarrying, tunnelling, and construction industries worldwide.

This 2003 machine is a down-the-hole (DTH) class unit, meaning it drives the hammer directly at the bit face for efficient penetration in hard-rock applications. It is configured as a single-pass unit, and at the time of listing it is operating with an 8-inch DTH hammer paired with a 9-inch bit. Included with the machine are two 6½-inch by 25-foot drill pipes along with the 8-inch DTH hammer. The mast measures 73 feet in length, providing substantial single-pass depth capability. The undercarriage is reported to be in excellent condition at approximately 85% remaining life.

Power is supplied by a Caterpillar 3508 engine, a large-displacement diesel engine well suited to the demands of continuous drilling operations. A notable feature of this machine is its larger air package option, equipped with a dual-operation air compressor that can be switched between low-pressure and high-pressure modes at the push of a button. In high-pressure mode it delivers 1,350 CFM at 350 PSI at 2,100 RPM, while in low-pressure mode it produces 2,000 CFM at 100 PSI, offering considerable versatility across different drilling applications and formations. A dust collector is also fitted, helping to manage cuttings and airborne particulate at the drill head. The machine is located in Kentucky, USA.
