Coupling Sleeves
Coupling sleeves are essential components in top hammer drilling, designed to connect drill rods and ensure efficient energy transfer with minimal power loss. Made from high-strength alloy steel and precision-machined for a perfect fit, our coupling sleeves provide maximum durability, wear resistance, and stability in the most demanding drilling conditions.
Available in semi-bridge and full-bridge designs, as well as multiple thread types (R32, R38, T38, T45, T51, ST58, ST68), our coupling sleeves are compatible with leading top hammer drilling systems from Sandvik, Epiroc, and Atlas Copco.
