Product Features

HL38 Length 170mm-190mm High Wear Resistance Crossover Drill Coupling Sleeve

Coupling sleeve also called 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.

Function: Coupling sleeve,Adapter Coupling

Type: Full-bridge,Semi-bridge, same/different diameter coupling

Application:
1. Underground Mining
2. Widely used in drifting and tunneling

3. Used in small hole drilling.

4. Bench Drilling

Features:
High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance.

Package: Carton or Wooden Box; also we can follow customers' requirements.

Delivery time is around 15-25 days.
