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