BENCH DRILLING 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. Thread: R25, R28, R32,R3212, HL38,T45, T51, Function: Coupling sleeve, Adapter Coupling Type: Full-bridge, Semi-bridge Our factory Shipment & package Factory : 1. We have 15-year engineering experience on drilling We can provide detailed solution for you by email,phone and even video if you have any problems while drilling 2. Professional quality control system Advanced equipment , International quality certification and ecperienced worker 3. In-time delivery 3 days if in stock; 15-20 days for production 4. Good after-service 1) Full compensation if it occurs that buttons are out ,broken and the body broken while button is worn less than 1/3 2) 24-hour online service 5. Strong production capacity.
