This machine specially be used to drilling bushing holes, rock bolt holes in the rock mass for the purpose of removing rock at the Mining site, stone pit, tunnel construction site, it be improved from disadvantage of crawler drills/pneumatic drills and It can simply attached to excavator to do drilling. We are only one manufacturer of attachment rock drill in Korea and it was developed by our self. Compare with crawler rock drill and pneumatic rock drill, our excavator rock drill has following advantages.

Competitive price Wide working range Low fuel cost Low labor cost Cable and wire-less control
