The EURODRILL RH4X is an X-series drilling head that transmits torque to the drill string. Its gearbox, tool connection and flushing arrangement define how the head is integrated into the drilling system. With the appropriate hydraulic percussion unit, the head is used for rotary-percussive drilling; the rotation-only version serves rotary drilling.
