S250 Pneumatic rock drill has been the preferred choice of miners who demand high performance, superior control and lasting reliability. the S250 Pneumatic rock drill allows operators to drill in confined spaces with challenging drilling directions while providing high drilling speeds and strong torque even at low air pressures. Push leg controls are integrated into the rear end of the rig to maximize safety and comfort. jackleg has a large contact area between the main cylinder components to reduce impact pressure and increase product life.

Performance

High penetration rate and strong torque even at low air pressure
Minimum downtime and low maintenance cost

Applications
S250 Rock Drill is used for rock drilling, blasting holes and other drilling works in the quarries, small coal mines and other constructions.
