Drifting Drill Steel is one major spare part in terms of drill area, drifting rod usually is hexagonal type.

Two ends threads can be used for connecting couplings, shanks, couplings or bits. Typically two ends of extension rods are male-male(MM Rod), while sometime one end is male and another one is female (we call it M/F rod).

 

Features:

● Made from steel as same grade as internationally well-known brand.

● Hollow drill steel processing by Boring Method ensuring quality reliability

● Optimize processing procedure, entirely automatic threading equipment to finish the thread naturally and reduce the concentration of stress.

● Shape once of whole heat-treatment ensures long lifespan

 

Thread Type:

For drifting rods, there are R22, R25, R28, R32, R38, T38, T45, T51 threads, and different lengths of rods are available from 600mm to 6400mm.
