Rock Drilling Mining Thread Drill Rod Top Hammer Drilling Tools Speed Rod

ModelThreaded Drill Rods

Diameter:25-87 mm

Length:600-6095 mm


>> Application

Thread drill rod other names extension rod, 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.
