Coupling Sleeve 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. Thread: R22, R25, R28, R32, R38, T38, T45, T51,T60 Function: Coupling sleeve, Adapter Coupling Type: Full-bridge, Semi-bridge Suitable for top hammers and drifter from Atlas Copco, Sandvik, Tamrock, Furukawa,Ingersoll Rand, Toyo, etc. Used in extension rod connection, its function is to transmit impact energy from the rock-drill piston, as well as rotation torque, into the drill string with no losses. It must withstand and transmit up to 6300 blows per minute from the piston continually, with great endurance and dependability.
