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.
