2.5 Inch R28 160mm CNC Milling Crossover Drill Coupling Sleeve
Drill rod 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.
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.
