Description

SINODRILLS Coupling Sleeves

Coupling is used for connecting shank adapter and extension drill rod together, or for connecting two extension rods together. Besides normal equal couplings, we also offer reducing couplings that are able for changing thread type and size. The couplings we offer can be applied for our top hammer drilling system, suitable for drilling duties in tunneling, construction, mining, quarrying, etc.
