Extension rod:
Other names areExtension drill steel, Extension drill rod, and Extension steel, M/Frod (Speed rod), produce Hexagonal and round cross-sections,Hexagonal rods are more rigid, heavier and transfer energy more efficiently,while increasing flushing. Round rods are generally lighter than hexagonal rodsand are normally used in extension drilling applications. With the longer steel tending to be larger in diameter, conventional extension steel is characterizedby duplicate thread on each end of the steel.Extension rods are made by hollow drill steels, different lengths are available from 600mm to 6400mm. This hollow hole are usually named flushing hole, used for transmitting water or air during drilling. And the threads can be used for connecting couplings, shanks adapters or bits.

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. The advantages of drilling with M/F steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.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. Longer steel larger in diameter, conventional extension steel, Hexagonal and round cross sections are available.
Carburizationis a process used to harder the entire rod surface both internally and externally to strengthen and extend the life of the rod.
High frequency induction is process where only the thread ends of the rod are hardened to lengthen thread life.

Sansung rock drilling extension rod are made with high quality of alloy steel bar and tungsten carbides with superior wear resistance and impact toughness superior, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy. They are widely used in all kinds of mining, drilling, quarrying, engineering, construction, water well drilling, oil exploring industries etc.

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. The advantages of drilling with M/F steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.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. Longer steel larger in diameter, conventional extension steel, Hexagonal and round cross sections are available.
Carburizationis a process used to harder the entire rod surface both internally and externally to strengthen and extend the life of the rod.
High frequency induction is process where only the thread ends of the rod are hardened to lengthen thread life.
