Blast Hole Drilling Rigs by L. M. P. Precision Engineering Co. Private Limited

We are leading Manufacturer, Exporter and Supplier of Blast Hole Drilling Rigs.

This is our flag ship. The biggest and the most powerful drill available in the Indian market.

The SK-60 is a crawler mounted unit that can handle 80% of large hole drilling requirements at about half of the cost of the larger machines.

Designed specifically for Coal Mining, the SK-60 is highly maneuverable, propelling from hole to hole rapidly.

The mast can be quickly load and raised with drill pipe in place especially valuable for long moves.
