Our sub saver 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 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.
·Drive chucks are built to the exact specifications of the original equipment manufacturer.
·Made of high-alloy steel for high strength and durability.
·CNC-machined for a perfect match with your drill rod."
