T38 Thread Tophammer Drilling Extension Rod for Drifting and Bench
Drilling
Product Specifications:
Sollroc extension rods are used throughout the world for top-hammer
production drilling in mining, tunnelling, construction and quarry
work. Extension rod, other names are Extension drill steel,
Extension drill rod, and Extension steel, M/F rod ( Speed rod ) ,
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.
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.
