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/F drill steel provides more rigid connections and is easier to uncouple 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.   Advantages: Compared with the oversea brands, our advantages are bellowing: •  Our products can match over 95% against the original products •  Price are competitive against the famous brands and best quality against the small factory Applications: • Underground mining • Tunneling,quarrying • Widely used in benching, and long hole drilling
