Precision CNC machining means that these drive chucks and sub-savers will keep your drill rod threads safe and sound. Boost your drive chuck’s life by adding a replaceable sub-saver to bear the brunt of the wear so your drill rod threads don’t have to.
Changing out worn sub-savers and drive chucks is an inexpensive and easy way to help get the maximum life out of your drill rod. If they are allowed to wear too much, then the drill rod thread will start to deform to the shape of the worn sub-saver threads. When attaching the drill rod to the sub-saver or chuck, be sure to torque it up to the correct pressure.
