Superdrill cupling sleeves

cupling 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. 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.

Semi-Bridge Coupling sleeve

Small non-threaded bridge in the center

Steel cannot thread past bridge area

Smaller diameter steel end portions fit together in the centre bridge area of the coupling

Semi-bridged couplings are most suited to high torque machines

Most rope and T threaded couplings are semi-bridged

Full-Bridge Coupling sleeve

Eliminates the potential for the coupling to creep along the threaded joints

Typically used in surface applications

Better uncoupling characteristics and tend to maintain tighter joints

Less chance of jamming

Best suited to machines equipped with independent rotation (i.e., S36IR rock drill)
