Our drifting and extension drill rods are for in drifting, tunneling, long hole drilling, bench and production drilling industries. These rods are produced with round or hexagonal sections in all common thread designs, and in Male / Male (M/M) or Male/Female (M / F) connections. All our drifting and extension drill rods are heat-treated with carburization or high frequency,combinated with phosphorization
T45 Threaded Drill Rod for Bench Drilling are made by hollow drill steels,there are two shapes of extension rods,round type and hexagonal type.This hollow hole are usually named flushing hole,used for transmitting water or air during drilling. And the threads can be used for connecting couplings,shanks,couplings or bits.
Usually for extension rods,there are R22, R25, R28, R32, R3212, R38, T38, T45, T51, ST58, T60 threads and different lengths of rods are available from 600mm to 6400mm usually.
Characteristics Hexagonal cross sections 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.
