Changing out worn sub-savers is an inexpensive and easy way to get the maximum life out of your drill rod. If they are allowed to wear too much, a drill rod’s threads will start to deform to the shape of the worn sub-saver threads. When attaching the drill rod to the sub-saver, be sure to torque it up to the correct pressure.
