The Epiroc DML is a crawler-mounted, hydraulic tophead-drive blasthole drill engineered for multi-pass rotary tricone and down-the-hole drilling in open-pit mines. Covering a hole diameter range of 150–270 mm (5 7/8–10 5/8 in), it delivers a clean single-pass depth of 9.9 m (32.5 ft) and up to 62.5 m (205 ft) in multi-pass applications. A reinforced main frame, double-cut tower lacing and proven DM-series systems ensure high availability, low operating cost and long service life.
