production process

certificate

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.
Our comprehensive range of bench and production rock drilling tools includes everything from 1” rope thread equipment all the way up to T60 thread equipment, Many customers say that our rods, tubes and button bits are the best on the market today. Let’s just say they will improve productivity considerably.
