What is a shank adapter?
Shank adapter is an important part of a rock drill and a drill string. During the drilling operation, the shank adapter transmits the impact energy and rotational torque of the rock drill to the drill string for breaking rocks through the drill bit to complete the drilling operation. In the drilling operation, the shank adapter not only has to withstand the high-frequency impact and strong torsion of the rock drill, but also is corroded and worn by the mineral water and slag. The working environment of the shank is extremely harsh, so the quality and performance requirements of the shank are very strict.
