ECM 720 provides a perfect balance of high productivity and cost efficiency. The combination of powerful HC 200A rock drill and the Strata Sense drilling control system allows you to drill through various rock conditions with high penetration rate and yet drilling straight holes. The extension boom helps quick and accurate collaring. Like the rest of the 700 series, simplicity of the 720 makes it easy to operate and easy to maintain. |
