First Break Mining
Rotary blast hole rigs
DML
Powerful rotary tricone and down the hole hammer drill for 149mm-250mm (5-7/8” to 9-7/8”) holes.
A legend in the drilling industry
The DML along with its little brothers, the DM45/50, is one of the most popular drills in the world for good reason.
The DML and DM45/50 have proven themselves in almost every mining condition to deliver productivity, reliability, and low operating cost year after year. If you survey operators around the world, you will see that many of them learned to drill holes with a DML or DM45/50 and can attest to its legendary capabilities.
The robust DML 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 DM45/50 make the DML easy to operate, especially for drillers who have experience in other DM series machines.
A reliable and industry proven hydraulic system, ensure the machine is rugged and well built for even the harshest mining conditions.
