Electronic Air Regulation System (EARS) is standart

EARS allows you to easily adjust your compressor to save horsepower and fuel consumption.

Multiple engine and air compressor options

A selection of engine brands and various high and low pressure compressors to choose from ensures you get the right configuration for our drilling application.

High speed feed and retract

An efficient, high speed feed system ensures higher overall penetration rates.

Look to the DM series of drills for the best value in quality, productivity and reliability to achieve your blasthole drilling objectives.

• The robust DM45/50 mainframe and tower design ensure a high asset life even in some of the toughest mining conditions. The double cut structural tower lacing ensures a strong tower structure without the added weight of less efficient designs.

• A spacious one piece FOPS (Falling Object Protective Structure) rated cab with electric over hydraulic controls that are common with the DM30 II and DML make the DM45/50 easy to operate, especially for drillers who have experience in other DM series machines.

• For single pass applications the DM45/50 can achieve a clean hole depth of 8.5 m (27.4 ft) and for multi pass depth can achieve depths of up to 53.3 m (175 ft).

• When more air and pulldown are required, the DM45 evolves into a DM50 to give added flexibility to the larger hole sizes in the DM45/50 range.
