External flush drill rod is used for percussion rotary drilling with down-the-hole (DTH) hammer (including hydro-hammer and pneumatic-hammer). High rigidity, good sealing ability and uniform outer diameter are structure feature of this drill rod. Therefore, it has advantages of low rotary torque and resistance.
Main dimensions of this drilling tool is given below.
