Product Description

Extension Drill Rod Drifting Drill Steel Alloy For Mining And Quarry Drilling Drifter Pipes

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.

It is common practice to bump up the drive end of drifting drill steel for added strength at the rock drill end to accommodate larger diameter and shank adapters. Drill steel is available in many standard lengths to match the drill feeds on a multitude of available drifting jumbos. Since the coupling does not enter the hole, a bit diameter closer to the steel diameter can be used. This enhances flushing and hole accuracy.

Drill bits, Couplings, Shank Rods and Tunnel Rods. Rod lengths 2440mm to 6435mm, (8'-21')in R25, R28,R35 bit end threads with standard shank end thread types. Hexagon body of H25-H35 and Round 39. Male/Female Tunnelling Rods are also available on 35mm Hexagon and 39mm Round.

Male/Female (M/F) Steel

Male/Female 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. This is fortunate because the coupling end cannot be replaced.
