In order to connect self-drilling hollow anchor bar to drill rig, shank adapter is usually installed under hammer drive for transferring torsion.
Functions:
Connect self-drilling hollow anchor bar to drill rig.
Features and advantages:
1.The product made of thick-wall steel pipe is dealt with machining and heat treatment. It is applied to high wear resistance conditions.
2.When using the reducing shank adapter, it is necessary to increase the locking torque at the large diameter end to prevent the anchor bar climbing into the chamber of large diameter.
3.Normally, expanding shank adapter is not recommended.
