Air leg rock drill YT29(S)
Rock drill
It is a tool for directly mining stones. It drills holes in the rock layers so that explosives can be put into them to blast the rocks, thus completing the quarrying of stones or other stonework projects. In addition, the rock drill can also be used as a breaker to break hard layers such as concrete
Rock drill characteristic
Light weight, generally less than 30kg, hand holding operation during operation. It can drill various small diameter and shallow blastholes. Generally, only downward holes and holes close to horizontal are drilled.
