Frequently Asked Questions


YES-PROBABLY! Hardrock-Vertex can match almost any shank configuration, bit attachment, dimensions, auger pitch, rotation, etc. in use today. We also have developed superior connection systems that are easy to couple and uncouple. However, we have our limitations.

Sometimes, but we can't work miracles! Since your rods are made to your specifications, we usually need a few days to manufacture your rods to our high standards. However, we are known for very fast response to orders.

The spiral flights on our rods act like big twist drills and material-handling devices: they auger or actively transport material out of the hole.

YES. We are shipping every week to every corner of the globe! We have shipped many repeat orders to Russia, China, Australia, UK, USA, Mexico, Antarctica, Finland, Peru... the list goes on.

The answer is a definite "probably"! Our products are made to industry ISO specifications relating to forged collars, tapers, threads, etc. We can manufacture our rods and bits to fit your existing set-up. However, you might want to tap our extensive experience to try to improve your drilling performance. Are you sure what you have is the best for your needs? Complete the contact form and we can chat about it.

For hard rock drilling, we suggest TURBINE section Auger drill steel, carburized to 55 Rockwell.

For soft rock drilling we suggest DIAMOND section Auger drill steel, carburized to 40 Rockwell.


YES. Hardrock-Vertex supplies both left- and right-rotation rods at your required pitch for either rotary or percussion drilling.

Hardrock-Vertex manufactures auger drill rods from 10” to 40 feet in length.

NO. Hardrock-Vertex auger drill rods are manufactured (hot-twisted, forged, machined) in one piece from high quality, high-nickel steel alloys. There are no welds to fail and there is a double flight that is rolled as part of the core. The alloy, plus the one-piece construction, also permits us to fully heat-treat each rod for better wear resistance than any welded product.

YES. Hardrock-Vertex manufactures Extension Auger drill rods to your specifications.

YES. Hardrock-Vertex manufactures JACKLEG drill rods with 7 or 11 or 12 degree tapers.

YES. Hardrock-Vertex manufactures and stocks drill bits and accessories to complement our Auger and traditional products.

Both Turbine and Diamond Augers are available in hollow or solid. That is only one of the advantages of our one-piece drill rods!


Traditional untwisted rods are useful for most standard drilling operations. However, auger drills typically can drill faster, straighter and cleaner than straight rods, and are more durable – especially in unstable ground.

An auger rod actively removes both drill waste and collapsing material while drilling. Augers will drill and clean the hole at the same time. If an auger rod ever gets stuck, simply reverse the rotation to retrieve the rod – it will “unscrew” itself, often with the bit still attached.

Almost every underground mine encounters unstable ground at some point. Why not have a few of our Hardrock-Vertex auger rods on hand so that you’re ready to drill in any conditions?

The outside diameter (edge of the flights) of a good-quality auger rod is a very close match to the cutting bit diameter, resulting in the rod running true in the hole. Hence, auger rods tend to stay straight, and not to rattle or sway.

The outside diameter of a good-quality auger rod is a very close match to the cutting bit diameter, resulting in the rod running true in the hole. The hole directs the path of the rod, which results in a straighter hole.

Less vibration results in less hand damage for the driller! Running true and having straighter holes results in less flexing of the rods so the risk of breakage is drastically reduced.


YES. Microscopic views of our twisted alloys show that the metal “fibres” are permanently aligned in a spiral pattern that increases flexural, tensile and compressive strengths. Rope is made in a twisted fashion for exactly the same reason.

YES. Our auger rods are made from high quality; high-nickel rolled steel alloys to the highest industry standards. This alloy (and the one-piece construction) gives us the flexibility to heat treat or carburize to a given hardness. This means our products can be used in a percussion environment.

We want you to eventually wear out our rods, not break them. Mine drilling rods have been around for over a century. During this time, much more powerful mining machines have been developed. Traditional untwisted mining rods often do not stand up to this abuse, especially because huge axial forces can cause untwisted rods to flex, vibrate and fail. Auger rods run true in the hole and vibrate much less. The high-nickel alloy used for manufacturing both our rotary and percussion rods also makes them more durable.
