About this machine

This Driltech D55SP is a used vertical drill — also referred to as a blast hole drill or down-the-hole drill — a type of machine used in mining, quarrying, and construction to bore precise vertical holes into rock and earth for blasting or sampling operations. Driltech is a well-established manufacturer of rotary and percussive drilling equipment, with a long history of building machines for surface mining and aggregate production applications. This example was manufactured in 2003 and is currently located in Kentucky, USA.

The machine is configured as a single-pass unit and belongs to the DTH (down-the-hole) class, meaning the hammer travels directly down the hole with the drill string, delivering impact energy at the bit face for efficient penetration in hard rock. It is currently set up with an 8-inch DTH hammer and a 9-inch drill bit, and comes equipped with two 6½-inch by 25-foot drill pipes along with the 8-inch DTH hammer. The mast measures 73 feet in length, accommodating the single-pass drill string configuration.

Power is provided by a Caterpillar 3508 engine, a well-regarded large-displacement diesel commonly used in demanding drilling and heavy equipment applications. The unit features a dual-operation air compressor as part of the larger air package option, switchable 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, giving operators flexibility to match air supply to the demands of different drilling conditions. A dust collector is also fitted.

The undercarriage is reported to be in excellent condition at approximately 85% remaining, indicating a well-preserved machine with substantial working life ahead.
