Product Description

Description:
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 andreliability.

- 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.

Fully carburised MF production drilling  rods for bench drilling

Extension rod, other names are Extension drill steel, Extension drill rod, and Extension steel, M/F rod ( Speedrod ) , 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 thesteel.

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.
