Rotary blast hole rigs
DM75
Powerful and reliable rotary tricone drill for 250mm -270mm (9-7/8” to 10-5/8”) holes.
Built on success
The DM75 is built on the past success of the DM-M2 and takes it one step further.
Look to the DM series of drills for the best value in quality, productivity and reliability to achieve your blasthole drilling objectives.
The DM75 can single pass drill holes up to 10 m (32.4 ft) and multi pass holes up to 53.3 m (175 ft).
The robust DM75 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 DM series product line make it easy to operate, especially for drillers who have experience in other DM series machines.
Proven hydraulic system that delivers on demand performance in the most efficient manner possible.
