R28-Hex28-R32,Drifter Rod (90500951)
Drifter rod, other names are tunneling steels, tunneling rod, drifting drill rod, has round and hexagon shapes available, most of drifting drill steel with drill steel hexagon is for tunneling and drifting drilling application. Hexagonal rods of rock drilling tools are more rigid, heavier and transfer energy more efficiently, while increasing flushing.
Bumping up the drive end of drifting drill steel is common practice 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 for drifting drill steels.
