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.
