Product Description

Drill Rods (Extension Rods & MF-Rods)

Drill rods are essential components for top hammer rock drilling. They are used to transmit impact energy and rotation from the rock drill to the drill bit.
Our rods are manufactured from high-quality alloy steel, heat-treated for superior wear resistance, strength, and toughness, ensuring long service life in demanding drilling conditions.

Product Features

High Strength Alloy Steel – Ensures durability and resistance to bending and breakage.
Advanced Heat Treatment – Provides excellent wear resistance and toughness.
Thread Accuracy – Precision threads for easy coupling and reduced wear.
Versatile Compatibility – Available for different thread types (R25, R32, R35, T38).
MF-Rods (Male-Female) – Reduce coupling connections, improve drilling efficiency.
Extension Rods – Allow deeper drilling with stable energy transmission.
