Top Hammer Rock Drilling Pipe Mining Machine Parts T45 Thread Extension Drilling Rod

Available in various lengths and diameter configurations, the T38 T45 T51 GT60 drill rod is ideal for deep drilling operations where accuracy, durability, and operational efficiency are critical.Its design supports extended service life with minimal maintenance, contributing to lower total cost of ownership and enhanced productivity in resource extraction and infrastructure projects.

Extension rods are made by hollow drill steels. 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.

Body Type:
There are two shapes of extension rods, round type and hexagonal type.
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.

Thread Type:
Usually for extension rods, there are R22, R25, R28, R32, R38, T38, T45, T51, ST58, T60 threads,and different lengths of rods are available from 600mm to 6400mm usually.
