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.
As one of China threaded drill rod manufacturers, KSQ is very mature in terms of raw material selection, production and processing technology, and product quality control, and can provide customers with high-quality threaded drill rods of various thread types. T38 drill rod is a very commonly used threaded drill rod, which has extension rod and quick change rod.
