T38 Length 190mm Dia55mm Drill Coupling Sleeve For Benching
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.
Specifications:
| Coupling | Length | Diameter | Thread | Weight, kg |
| mm | inch | mm | inch |
| 190 | 7 ½ | 55 | 2 5/32 | T38 | 2.1 |
Standard coupling using T38 thread system. Used in benching and
long hole drilling.
Applications
• Underground Mining
• Widely used in drifting and tunneling
Used in small hole drilling.
Competitive Advantage
High strength chromium-molybdenum steel with high fatigue strength
and excellent wear resistance
Couplings are used to well connect the shank adapter to the drill
rods or well contact two extension rods for transmitting energy. It
has standard type coupling and crossover coupling.
