Male shank adapters are generally suited for drifting, tunneling and extension applications where high stresses are present. Female shank adapters are used when the drilling space is limited. Top quality of alloy steels, CNC machining and advanced heat threatment ensure our reliable quality.
HENGLONG shank adapters are there fore designed to with stand the high impact power of modern rock drills and made from specially selected material which also is hardened through cauterizing. Around 300 different shank adapters suitable for different rock drills are currently available from Atlas Copco series drifters, Sandvik, Tam rock series drifters, Garden Diver series drifters etc..
