Our extension drill rods are used to extend the drill string in percussive drilling applications. They transmit impact energy and torque to the drilling tool and enable drilling at greater depths.

Our extension drill rods offer:

-   Various rod lengths
-   Different thread systems from R22 to GT65
-   Available as MF rods or with male threads at both ends
