Drifting rods has Round and hexagon rod available, most of drifting drill steel with drill Steel Hexagon is for tunneling and drifting drilling application. Hexagon rods are more rigid, heavier and transfer energy more efficiently, while increasing flushing.
It is common practice to bump up the drive end of drifting steel for added strength at the rock drill end to accommodate larger diameter and shank adapters. Drill steel is available in many standard lengths to match the drill feeds on a multitude of available drifting jumbos.
Two different types of heat treatment are used to strengthen our percussive drill string components to maximize their performance and reliability.
– Carburization is a process used to harden the entire rod surface both internally and externally to strengthen and extend the life of the rod.
– High Frequency Induction is a process where only the thread ends of the rod are hardened to lengthen thread life.
