T45 Round46 Speedrod male-female drill rod for long hole dilling
Description:
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.
