R38 Length 170mm-190mm High Wear Resistance Crossover Drill Coupling Sleeve
Coupling sleeve also called 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.
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. We can manufactures semi-bridge, full bridge coupling sleeves for the percussive tools.
