Spear Drill is mainly used to drill holes to install anchor rod or anchor rope for coal roadway supporting, or other tunnel. Usually the hardness of rock is less than or equal f10. It also can be used to install resin anchor rod and anchor rope, and meet the requirements of the early anchor preload force.
Applications
- Coal Roadways
- Rock Lanes
- Tunnels
Features
- Small in size, light weight, simple manipulation and easy maintenance.
- Gear type pneumatic motor, stable running and high reliability.
- Simple and compact structure
- Low noise and low maintenance
