Couplings

Known as coupling sleeves, couplings are used for connecting drill rods and shank adapters. With threads of R38, T38, T45 and T51, the couplings are divided into normal couplings and crossover couplings with full bridge or half bridge. The couplings are widely used in surface mining, underground mining, tunneling, bolting, furnace tapping, tunnel construction, hydropower projects, quarrying and construction.
