Epiroc R drill strings

Maximized efficiency and durability

At Epiroc, we are committed to providing our customers with the highest quality rock drilling tools and equipment. One of the key components that ensure the reliability and efficiency of our drilling operations is the industry standard R thread. The “R” stands for “rope,” reflecting its robust design and exceptional performance, which are widely recognized and used in various drilling applications.

The R thread is engineered to withstand the high stresses and loads encountered during rock drilling operations. Its robust design ensures a secure and reliable connection between drill string components, reducing the risk of breakage and downtime. This durability translates to longer tool life and lower maintenance costs for our customers.

The precise threading of the R thread allows for quick and easy assembly and disassembly of drill strings. This efficiency is crucial in minimizing downtime and maximizing productivity on the job site. With the R thread, our customers can achieve faster drilling rates and complete projects more efficiently.

The R thread is an industry standard, making it compatible with a wide range of drilling equipment and accessories. This versatility ensures that our customers can easily integrate Epiroc’s R thread drill strings into their existing setups, providing a seamless and cost-effective solution for their drilling needs.

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.
