Rock drill is a tool used to directly mine stone. It drills holes in the rock formations to put explosives into the rock to complete the mining of stone or other stonework. In addition, rock drills can also be used as destroyers to break hard layers such as concrete. According to its power source, rock drills can be divided into four categories: pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills.
