Drive chucks and sub savers are essential components in horizontal directional drilling that connect the drill string to the rig’s drive system. The drive chuck mounts directly to the rig’s spindle, transmitting torque and rotational force to the drill pipe. To extend the life of this high-wear connection point, a sub saver is used as a replaceable interface between the drive chuck and the first drill rod. Built for durability and precision fit, these tools protect the rig’s drivetrain and reduce maintenance costs by absorbing wear where it matters most. Radius offers drive chucks and sub savers compatible with Universal, Vermeer, and Ditch Witch drills, ensuring reliable performance across all major HDD platforms.
