In top hammer drilling, the shank adapter transmits impact energy from the piston to the rod(s) or tube(s). Additionally, rotation torque is delivered via the shank adapter.

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. 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
