Full Pneumatic rock drill bits

Down-the-Hole Drill Machines are mainly used for perforation working during stone quarrying. Rock drill bits commonly used for drilling use a pneumatic system: the energy thrust is transmitted by compressed air. In fact Rock drill bits need air compressors. The pneumatic hammers penetrate the rock mass by means of a drill rod that is nothing more than a shaped steel rod. The pneumatic system is supported or sometimes substituted by the hydraulic system in which hydraulic oil instead of air is used to transmit the energy.
