T45-φ46-T45 Mining Drill Rod Machine Tools Thread Drill Rod
Product Description:
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 the steel.
For Extension Rod and M/F steel process, the Carburization of heat
treatment are used to strengthen high speed and powerful percussive
drill string components to maximize their performance and
reliability.
Carburization is a process used to harden the entire rod surface
both internally and externally to strengthen and extend the life of
the rod.

There are two shapes of extension rods, round type and hexagonal
type.
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
