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 and middle frequency induction surface quenching as two process for strength the total quality and performance and life.
