Introduction of coupling sleeves:
Coupling sleeve for Extension Drill Rod connection.High quality of alloy steels and CNC machining guarantee our reliable and consistent quality control of coupling sleeves
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.
Coupling sleeves are also used to connect several rods to each other in the same way. Coupling sleeves have a middle stop to prevent over-threading on to the drill rod.
Applications
R25, R28, R32, R38
Used in drifting and tunneling.
T38, T45, T51,T60,ST58,ST68
Used in benching and long hole drilling.
Processing
CNC milling and proprietary heat treatment process
Competitive Advantage
High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance
