This Atlas Copco ECM660 III is a vertical drill — also commonly referred to as a rock drill or down-the-hole drill — a type of machine used in surface drilling operations such as mining, quarrying, construction, and geotechnical work. Atlas Copco is a well-established Swedish industrial manufacturer with a long history of producing drilling equipment, compressors, and related machinery for the mining, construction, and energy sectors.
This 2004 unit is equipped with a Montabert HC160 drifter, a hydraulic rock drilling unit that delivers the percussive force used to break and penetrate rock formations. The drill is rated for the 3.5 to 4.5 inch hole class, indicating the range of drill bit diameters it is configured to work with.
The machine has accumulated 7,036 total frame hours, with 2,251 of those hours logged as percussion hours — a more targeted indicator of drifter wear, since the percussive system is the highest-stress component in a rock drill. The relatively lower percussion hours compared to total frame hours suggests the unit has spent meaningful time in non-drilling modes such as tramming or repositioning. The seller describes it as a very well maintained unit.
Located in Kentucky, USA, this is a used machine offered in used condition.
