Product Information

Coupling Sleeve is a sleeve–shaped rock drilling component with internal threads for connecting shank adapter and drill rod, or drill rod and drill rod. 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 .

We Supply Standard Coupling Sleeve 

Standard coupling sleeve, also known as semi bridge coupling sleeve, has a section of the bridge without a thread in the middle. The threaded part of the drill pipe cannot be screwed through the bridge part of the coupling, and the end of the thread can closely adhere to the casing bridge zone. Standard coupling sleeve is particularly suitable for high-torque drilling rigs. Most rope thread (R thread) and trapezoidal thread (T thread) coupling sleeves are with half-bridge type. The half-bridge type is by far the most widely used couplings.

Size Of Coupling Sleeve : T38 / T45
