Detailed Product Description

Mf Mm Speed Extensioin Thread Drill Rod

Extension rod, other names are Extension drill steel, Extension drill rod, and Extension steel, M/F rod ( Speed rod ) , Produce Hexagonal and round cross sections, Hexagon rods are more rigid, heavier and transfer energy more efficiently, while increasing flushing. Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications. With the longer steel tending to be larger in diameter, conventional extension steel is characterized by a duplicate thread on each end of the steel. 

Male/Male rod,Male/Female(M/F)Rod-Speed rod M/F drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/Fdrillsteelprovidesmorerigidconnectionsandiseasiertouncouple and handle. The service life also tends to be better than with separate couplings. 

For Extension Rod and M/F steel process, the below two different types of heat treatment are used to strengthen high speed and powerful percussive drill string components to maximize their performance and reliability.-Cannibalization 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. 

 

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. 

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