The top hammer type rock drilling bit is mainly used for blasting hole excavation of open pit rock drilling, underground roadway, tunnel excavation, hydropower station and other infrastructure projects. The connection mode is mainly T-threaded connection and R-shaped thread connection. The top hammer type hydraulic rock drill rods equipped with drilling rigs and open-air drilling rigs are used to receive the energy transmitted by the rock drill to achieve the effect of breaking the rock.
