Epiroc SR drill strings

Drill strings for sustainable productivity

Adapted to the new generation of powerful hydraulic rock drills, the Epiroc SR drill string family transmits that power into the rock efficiently and reliably. With a faster rate of advance, it lowers the cost per drill meter, boosting productivity and increasing safety and operator focus.

With more material to resist the stresses leading to thread breakage, the Epiroc SR drill string family has a substantial increase in fatigue strength, with fewer tensile shock waves it reduces the stress in the string for less wear on the rock drill, and drill rig components extending the service life.

A stiffer rod means there is less breakage, maintenance can be planned, and productivity optimized with straighter and more accurate holes drilled.

Straightness and accuracy. Pure perfection

The conical shape means more quality material at the rod end to prevent breakage with less tendency for deviation when collaring. High quality materials combined with state-of-the-art manufacturing mean drifting equipment ready to hold up to heavy duty drilling cycles with superior product life.

Sustainability

The drill string is adapted to a new generation of powerful hydraulic rock drills with a considerably longer rod life and less wear thanks to the design of the conical shaped rope thread that facilitates rapid coupling and uncoupling.

Operator in focus

High operator acceptance thanks to easy coupling and uncoupling of the drill bits. Easy uncoupling provides a safer working environment and a happier operator.

Improved performance

Designed to reduce tensile shock waves in the drill string, a higher fatigue strength improves resistance and reliability, raising productivity with less wear, better fuel efficiency and sustainable drilling.

Protected by diamonds with the new PCD technology

Drill bits where the buttons are coated with diamond protect your people, your productivity and the environment. The technology is called PCD (polycrystalline diamond) and is used in our new drill bit range. Explore how a two-millimeter diamond layer can help you improve workplace safety, reduce downtime and minimize CO₂ emissions.

Eliminate live work - Improve safety with fewer drill bit changes.

Expand the potential of automation - Boost productivity by drilling without interruption.

Cut down CO2 emissions - Reduce the amount of CO2 emissions per drilled meter – by up to 90%.

For miners who want to push it to the limit

Drill more meters every day and between regrinds, while enjoying longer bit service life. It´s simply a drill bit for miners who won´t settle for anything but the fastest, most productive underground drilling imaginable. 

Increased service life - The premium Epiroc grade of carbide is harder and tougher than  ever before.

Improved rate of penetration - The bit design gives an optimized balance of bit diameter wear and penetration rate.

Straighter holes - By keeping a tighter match in between head and skirt diameter enables the bit to drill straighter holes due to less angular deflection.

A new assortment of bolting bits

The new assortment of bolting bits are designed to enhance efficiency and reliability in rock drilling operations. With innovations like Trubbnos button technology, these tools deliver longer service life, higher Rate of Penetration (ROP), and lower Total Cost of Ownership (TCO).

Longer service life - Enhanced durability ensures the bit diameter remains consistent, which is crucial for bolting operations.

Higher Rate of Penetration (ROP) - Optimized button designs and a new flushing system contribute to faster and more efficient drilling by quickly removing rock debris.

Lower Total Cost of Ownership (TCO) - Increased productivity and reduced maintenance requirements result in tangible cost savings.
