T45 Thread Coupling Sleeve full bridge 210mm connection drill rod for Breach Drilling

Coupling sleeve

Coupling sleeves, when using rock drills with male shank adaptersand a conventional drifter rod, a coupling is required to join the adapter to the rod, ensuring the ends touch for efficient energy transmission. Couplings are also used to connect several rods to each other in the same way. Couplings have a middle stop to prevent over-threading on to the drill rod.
