To reduce hole deviation and/or increase drilling tool life, good core barrel stabilization is important. Besides the reaming shell, the locking coupling is a key component for good barrel stabilization. Standard steel locking couplings may wear prematurely in abrasive and/or broken conditions. Our diamond impregnated locking couplings with full hole body will dramatically increase the life of the tool; keeping nominal gauge for a very long time. With our components, you can drill with confidence!
