T38 ,T45 China Threaded Extension MM Rock Drill Rod for Drilling

Product Description

In the rock drilling process, the drill rod is subjected to the impact force of the rock drill piston, high torsional stress and axial thrust through the shank adapter, as well as the additional bending stress caused by the weight of the drill rod, the reaction force of the rock and the asymmetric impact of the drilling operation. Therefore, the quality of drill rod plays a very important role in the efficient completion of rock drilling operations.
