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.
Both semi-bridge and full-bridge coupling sleeves are manufactured by us in different sizes as below:
Thread sizes: R25, R28, R32, R35, R38, T38, T45, T51.
Semi Bridge Coupling: R32-R25 R32-T38
Full Bridge Coupling: R32-R32 T38-T38
Thread R Thread, T thread.
Length: 140mm-250mm. Special length is available by request.
