1 Product feature of Rock Drilling Tools
Description: Extension rods, also known as extended drill rods, extended drill rods, extended steel, M/F rods (Speedrod), produce hexagonal and circular cross-sections, hexagonal rods are harder, heavier, and transmit energy more effectively, while increasing flushing. Round rods are generally better than
Hexagonal rods, usually used for extended drilling applications. Since longer steels tend to have larger diameters, traditional extension steels are characterized by a repeating thread at both ends.
steel.
Male/Male Rod, Male/Female (M/F) Rod-Speed ​​Rod
M/F drill steel is a substitute for the coupling sleeve, and the internal thread part of the threaded connection is used as a component of the drill steel. M/F drill steel provides a more rigid connection and easier separation
And processing. The service life is also often better than a single coupling.
For the extension rod and M/F steel process, the following two different types of heat treatment are used for
Strengthen the high-speed and powerful percussion drill string assembly to maximize its performance and
reliability.
Carburizing is a process used to harden the internal and external surfaces of the entire rod
Strengthen and extend the life of the rod.
High-frequency induction is a process of only hardening the threaded end of the rod to lengthen it
Thread life.
