Rock drilling tools manufacturer ProDrill produces shank adapters for
most models of current prevailing rock drill machines. All ProDrill
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.
Shank Adapter, also known as Shank Bar andStrike Bar.
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).
Prodrill 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.
Two flushing options of shank adapters: internal or external
— Internal flushing uses a water tube that fits through the center of
the drill and into an o-ring seal in the end of the shank, to transfer
flushing into the drill string
— External flushing, holes or a slot are required in the side of the
shank adapter.These line up between seals inside the front head or water
box of the rock drill, when the shank is installed. Flushing medium is
supplied directly to this device and is introduced into the drill string
through the shank
— External flushing is considered superior to internal flushing, as
greater volumes of flushing agent can be delivered with less risk of
leakage and hammer damage from water
The shanks for hydraulic drills and some pneumatic drills have
external or front head flushing. Hydraulic shanks generally have at
least 5 to 14-spline configuration, Pneumatic shanks tend to have
internal or through flushing and can generally be identified by their
lugs or 4-spline configuration.
