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.
