Atlas Copco has years of experience drilling with integral drill steel in underground and surface applications. To meet the tough demands of our many customers in the dimensional stone and underground mining industries, we’ve continued to invest in the production of premium quality integral drill rods. The Secoroc product range of high quality integral drill steel from 0.4 m to 11.2 m in length has helped customers around the world get the most out of their operations. To meet diverse demands, we supply hexagonal rods, 19 mm and 22 mm in a wide variety of lengths and bit dimensions.
The lowest cost per metre drilled is our guiding principle at Atlas Copco Secoroc. To live up to this motto, we never compromise on quality. That’s why we didn’t settle for less than super tough C253 steel when we designed our integral drill rods.

Inserts are subjected to a high quality bronze-brazing process – using just the right temperature and technique – to reduce the risk of carbide failure. And the shank is through-hardened to ensure the highest possible toughness and wear resistance.

What’s more, our integral drill rods are unique in featuring a rolled-in stainless steel lining in the flushing tube for unrivalled anti-corrosion protection.

”The lowest cost per metre drilled” has long been synonymous with Secoroc products. Our Uppercut tapered equipment is no exception. In fact, we're confident that you'll be enjoying higher drilling productivity, straighter holes and longer service life than ever before.

Tapered products first appeared on the scene in the 1960s. To say that quality has improved since those bygone days is an understatement. With benefits like above, it's easy to see why tapered equipment is grabbing market share from integrals- especially in mining applications and the dimensional stone industry. To us, it makes perfect sense.

Bits with bite
The Secoroc Uppercut range compromises button and cross-type bits in an extensive selection of design configurations. Moreover, we've added two new models with an extra front button for improved hole straightness, higher penetration rate and a longer service life. These designs can be used in a variety of rock formations for maximum productivity. Furthermore, our range of ballistic button bits is in the process of being extended to meet ever more diverse demands.

Tough rods for a tough life
Rods have a tough life, transferring the percussion energy from rock drill to bit and then into the rock. They're also subjected to high bending stress, not to mention corrosive water in the flushing hole. These harsh facts have not only guided us in our selection of steel quality, manufacturing technique and heat treatment processes, but also in our decision to have a rolled-in stainless lining throughout the entire length of the flushing hole.

Atlas Copco Secoroc has been a leader in the field of developing equipment for underground rock drilling applications for a long time. The product range has always been very modern and comprehensive. High quality conventional Rope threaded equipment (shank adapters, male-female speedrods, as well as male-male rods plus couplings, a multitude of drill bits of different designs and reaming equipment) has been available from thread size R25, R28 and R32 up to R35. These tried and tested thread systems have served drillers well for many years. However, with the introduction of ever-more powerful hydraulic rigs, these battle-worn solutions started to show weakness. Rod breakage at the bit end, either just behind the skirt or on the last thread, was becoming distressingly common. Why? Because it’s the most vulnerable part of the rod. Consequently, bits were lost, leading to costly downtime. Even worse, holes often had to be re-drilled, sending productivity the wrong way. Putting it bluntly, drifting equipment was struggling to cope with the power of the new rigs. It was high time for fresh ideas. Intensive development by Atlas Copco Secoroc has come up with the new Magnum SR range. The Magnum SR solution is based on a patented new conical thread design which will make it possible to drill the same hole sizes as with conventional drill strings. However, the Magnum SR rods have a much larger cross-section than conventional rods, in short – more material where it’s really needed. Rod fatigue resistance is improved, tendency to deviate during collaring is reduced and coupling and uncoupling of bits is easier.

Atlas Copco Secoroc is genuinely confident that Magnum SR marks the dawn of a new era in drifting and tunnelling, as well as for rock bolting. The success of this new innovative system is beyond dispute. Major mines in Sweden, Canada and Australia have switched completely to Magnum SR equipment. Drillers using it are not only drilling more and straighter holes than before, they’re also finding that Magnum SR lasts longer than any competing solution.

COPROD belongs to the product line Tophammer, even if it differs from conventional tophammer drilling. Drillers always dreamed of a system that would combine the straightness and accuracy of down-the-hole drilling with the enormous capacity of hydraulic tophammer drilling. Efforts to combine the advantages of the two techniques were unsuccessful, until the development of COPROD by Atlas Copco.

The COPROD system combines the speed of tophammer drilling with the precision and long service life of the down-the-hole method.

Inside each rigid, threaded pipe section is an impact rod. It is furnished with stop lugs to hold it in place inside the pipe section. The COPROD sections are joined together via the drill pipes. Since the drill pipes transmit rotation force only, stress to the threads is minimal, and their service life is very long. All negative effects of the transmission of impact energy through the threads are eliminated entirely. The result is high impact power with minimal wear. Since the outer pipes are smooth, and flush along the entire length of the drill-string, it is almost impossible for jamming to occur.

Practical experience with COPROD has been exceptionally good. The method gives good overall economy, particularly in large-scale production drilling, and when drilling in fissured or otherwise demanding rock conditions.
