Product Description:

Extension rod, other names are Extension drill steel, Extension drill rod, and Extension steel, 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 the steel.

Carburization is a process used to harden the entire rod surface both internally and externally to strengthen and extend the life of the rod.
