Blasthole drilling rig DM series

rotarydown-the-holeautomatic

The DM45/50 rotary blasthole drill rig, along with its larger counterpart the DML, are among the most popular drills globally, recognized for their productivity, reliability, and low operating costs in a wide range of mining conditions. The robust DM45/50 mainframe and tower design ensure a long asset life, even in the toughest mining environments. The double-cut structural tower lacing provides a strong tower structure without unnecessary weight. When additional air and pulldown are needed, the DM45 can be upgraded to a DM50, offering flexibility for larger hole sizes within the DM45/50 range.
