High Air Pressure Down The Hole Hammer , Ore Mining Dth Hammer Drilling

DTH Reverse Circulation RC Hammer And Drill Bit

Technical Parameters

RC hammer:the exhaust air,and cuttings are discharge through the center return hole of the RC hammer,and the exhaust air is not discharged into the ground,It creates excellent up-hole velocity,which ensure cuttings are quickly removed from the bit face providing an extremely clean hole and excellent life time on the bit.
