Shank adapter for pneumatic rail-mounted rock drill

External threaded shank adapters are generally more suitable for tunneling and extension drilling operations where high bending stresses are present, while internal threaded shank adapters are better suited for applications with limited drilling space and where the total feed length is critical.

Description

Shank Adapters for Pneumatic Rail-Mounted Rock Drills

All shank adapters in this series are designed for pneumatic rail-mounted rock drills and can be produced with either external or internal threads as required. One end of the shank adapter connects to the rock drill, while the other end connects to the drill rod, making it a vital component between the rock drill and the drilling tools.
