Description:

drifter rod, another names are tunneling steels, tunneling rod, drifting drill rod, 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. This top hammer drifter tools 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 and middle frequency induction surface quenching as two process for strength the total quality and performance and life.

 

Product figures:

Hexagonrods are more rigid, heavier and transfer energy more efficiently,while increasing flushing, Carburization is a process to harden entire rod surface both internally & externally to strengthen rod life, Middle frequency induction surface quenching is a process where onlythread ends of rod are hardened to lengthen thread life.
