The Atlas Copco ECM720 is a used vertical drill — sometimes referred to as a down-the-hole drill or DTH drill — a type of machine used in rock drilling applications such as mining, quarrying, and construction, where a percussive drill string is driven vertically into the ground to bore blast holes or production holes. Atlas Copco is a well-established Swedish industrial group with a long history of manufacturing drilling, compressed air, and mining equipment for surface and underground operations worldwide.
This 2008 machine is configured for the 4.5- to 5.5-inch hole class, making it suited to medium-scale production drilling within that diameter range. Percussion is provided by a Montabert HC200A drifter, a hydraulic rock drill unit known for delivering high-frequency impact energy to the drill string. Power comes from a Caterpillar C11 diesel engine, a robust in-line six-cylinder unit commonly found in heavy construction and drilling machinery. The drill steel setup is currently configured for 60 mm drill rods.
At only 3,570 total hours, this machine has accumulated relatively low usage for its age, which is a notable point regarding its remaining service life and the likely condition of wear components. The machine is located in Kentucky, USA, and is offered in used condition.
