The shank adapter is a part connected with a rock drill at one end and a drill rod at the other end. It is an important part of rock drills and drilling tools. It is mainly used in mining operations, using high-quality alloy steel as raw material, and has undergone overall carburizing treatment. Special CNC ensures quality of shank, internal water holes, and side water holes. The shank adapter is uniformly heat treatment and scientifically straightened with precision instruments to ensure straightness and resistance. The working environment is harsh, so the quality and performance requirements of the shank adapter are very strict.
During the rock drilling operation, the rock drill transmits the impact energy and rotational torque to the rock drilling tools through the shank adapter and the rock is broken by the drill bit. In the rock drilling operation, the shank adapter not only bears the high-frequency impact and strong torsion of the rock drill but also suffers corrosion and wear by the mineral water and slag.
Shank adapter includes two types: shank adapter for pneumatic guide rock drill and hydraulic rock drill shank adapter.
At present, there are more than 200 kinds of rock drilling machines of various types, and different types of rock drilling machines need to choose different shank adapters.
Shank adapter for pneumatic guide rock drill: It is suitable for the small rock drill and can be operated manually.
Shank adapter for Atlas Copco rock drill: It is suitable for Atlas Copco rock drill, one of the most commonly used rock drills.
Shank adapter for Sandvik/Tamrock rock drill: It is suitable for Sandvik/Tamrock rock drill, one of the most commonly used rock drills.
Thread size: R28, R32, R35, R38, T38, T45, T51.
