Rock drilling tools manufacturer Bloom produces shank adapters for most models of current prevailing rock drill machines. All Bloom shank adapters are carburized, CNC manufactured, and made from premium steel. Thus ensure them with superior toughness and anti-fatigue strength to meet the most demanding drilling conditions. Moreover, all shanks could be produced with ether male or female threads if there is actually necessary.

Male shank adapters are generally better suited for drifting, tunneling and extension applications where high bending stresses are present. While female shank adapters are used when the drilling space is limited and the total feed length is important, for example underground roof bolting.


The task of the shank adapter is to transmit rotation torque, feed force, impact energy and flushing medium to the drill string (extension drill rods, drifting drill steels).


Bloom 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, Tam rock series drifters, Garden Diver series drifters etc.
