Product Description
T38 3660mm Extension Drilling Rods with M/F Thread Design
Premium Threaded Extension Rods for Efficient Drilling
Our extension rods (also known as extension drill steel or speed rods) are manufactured in both hexagonal and round cross-sections. Hexagonal rods offer superior rigidity, better energy transfer, and improved flushing, while round rods are lighter and ideal for extension drilling applications.
M/F Rod Advantages
The Male/Female (M/F) threaded design eliminates the need for coupling sleeves, providing more rigid connections that are easier to uncouple and handle. This integrated thread design extends service life compared to separate couplings.
Advanced Manufacturing Process
All extension rods undergo carburization heat treatment to harden both internal and external surfaces, strengthening the rods and maximizing their performance and reliability under high-speed percussive drilling conditions.
