shank adaptors ensure a quality drill string interface to the most exacting industry tolerances. Built to seamlessly interface with hydraulic and pneumatic drifters and top hammers, our shank adapters come in a full range of industry-standard thread configurations. Our precision grinding process ensures straightness, and our tools are fully carburized with an advanced heat treatment. Different shank adapters are available, like Atlas Copco, Tamrock, Ingersoll Rand,etc. Also for the same drill machine, due to different applications, the shank adapters can be different length and different threads:

Atlas Copco (COP1238, COP1838, COP1032 and etc)

Furukawa (HD715, HD612, HD609, PD200 and etc)

Ingersoll-Rand (VL140, VL671, YH80A and etc)

Tamrock(HLX5, HL600, HL500, HL300, HL 700, HL850, HL1000, HL1500 and etc)

Male shank adapters/striking bar 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/striking bar is to transmit rotation torque, feed force, impact energy and flushing medium to the drill string (extension drill rods, drifting drill steels).

The shank adapters/striking bar are therefore 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.
