Tophammer rods and tubes

Secoroc's rods are manufactured with an own-specified steel grade and cutting-edge heating process, which creates an ideal balance between abrasion resistance and flexibility.

More material where it’s needed.

Thanks to our unique patented conical thread systems, we’re confident that rod breakage is a problem you will see a lot less of. More material at the rod end not only strengthens the product, but also minimizes deviation during collaring. The result? Straighter holes and a much longer service life.

The common denominator for both systems is thicker and stronger rods with the same bit diameter as an equivalent R or T threaded system. This means less downtime, straighter holes and greater productivity. In addition, rods and bits are much easier to couple and uncouple.
