The Gefco SS25K is a used vertical drill — also known as a drill rig — a type of machine designed for boring into the ground and used across applications such as water well drilling, geotechnical investigation, and mineral exploration. Gefco, also marketed under the Speed Star name, is a recognised American manufacturer of drilling equipment with a long history of supplying rigs to the water well, environmental, and construction drilling industries.
This particular rig is a top-head drive unit with variable speed rotation, a configuration favoured for its versatility across different formation types and drilling methods. It is truck-mounted on a 1990 International VT100 chassis powered by a Cummins 400 engine paired with a 10-speed transmission, and the truck carries approximately 56,000 miles. The VIN recorded for the carrier vehicle is 44KHM6488LWZ17237.
The rig is equipped with a 900 CFM air compressor rated at 300 PSI, supplying the compressed air capacity needed for air rotary and down-the-hole hammer drilling. A Gardner Denver 5×6 mud pump is also fitted, enabling fluid rotary drilling. Stability during operation is provided by four levelling jacks.
Included with the machine is a substantial string of drill rod — 1,200 feet in total, comprising sixty 20-foot sections of 3½-inch rod. Three hammers are also included: one measuring 8 feet in length and two measuring 6 feet each.
The rig is a 1990 model and is listed in used condition, located in Illinois, USA.
