Product Description
Mining drill bits are mainly used for perforation working during stone quarrying. Mining drill bits cmmonly used for drilling use a pneumatic system: The energy thrust is transmitted by compresseddrill hammer air. In fact mining 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.
