Drill Rods
full automation with a human touch
Your drill rods are produced via our automated production process.
This ensures that every rod we produce will be consistent with the next so that you can be confident in your drill string.
We have built our production line with equipment that are renown for their ability to work within extremely tight tolerances, such as the Mazak quick turn, for the machining of our threads.
But just to be sure, after each stage of the production process, a technician physically inspects and approves the work, before the drill rod can make it's way down to the next stage.
This means that at every stage of our production, we are committed to producing drill rods that are consistent and ensuring this through our stringent means of quality control.
Proprietary Steel
Not all steel rods are made for drilling, that's why, with the help from the University of Shanghai and "Bao Steel Shanghai" our steel supplier, we have co-developed our own proprietary steel, specifically designed for drilling applications.
Based on 4130, this special variant has better flex and retention than the standard.
double heat treatment
To ensure that the threads have a longer working life, our threads are heat-treated twice, in two separate stages.
The first stage heats up the threads to the desired temperature then is immediately cooled with water.
In the second stage, the thread is simultaneously heated whilst cooled with water.
providing a more consistent process.
Even the area's above the threads are heat-treated, to protect the rods from breakout tools and jaw clamps.
Individually inspected at each production stage
At every stage of the production process, each individual drill rod is inspected for the work carried out, before it can pass onto the next part.
It starts right even before the production, our raw materials are inspected and analysed to ensure that they meet our stringent requirements.
Technicians at every production stage inspect and supervises the work carried out by the machines on every single drill rod.
truness
Using the measuring instruments below, each drill rod is rotated and checked for its trueness, only a small deviation is acceptable. This allows for the drill rod to sping straighter, improve thread life and minimising rod slap, which may lead to snapping rods down the hole.
Thread inspection
To ensure that the threads have been machined to perfection, each rod is greased and hand tightened to a standoff point between 1.3mm-1.6mm with minimum resistance.
The rod is then regreased and then tightened to correct torque specs, to form a zero mm gap joint that is water tight.
