Epiroc T drill strings

It´s all in the thread

The Epiroc T drill string has a tough thread system. In fact, it’s robust enough to prevent product breakage in the blast hole. Which means you can shift your focus from all those time-consuming rod and shank changes to maintaining a much leaner stock.

Our drilling system comes in five dimensions: T35, T38, T45, T51 and Epiroc T60. Epiroc T speedrods are ideal for bench and production drilling, and are available as extension or drifting drill rods.

What’s more, the T range of shank adapters will work wonders with your equipment – whether you’re running an Epiroc drilling rig, or some other brand.

Epiroc’s comprehensive range of tophammer drill bits matches the T drilling rods to perfection with the added benefit of being easier to release and change.

Power in tophammer surface drilling

The bits are built to take on any rock, from hard to soft, and from abrasive to non-abrasive. These bits last much longer. They give the drillers more meters before the first regrind, and many more meters between the regrinds. With the bits, drillers are guaranteed to get more performance from each bit. 

Greatly improved service life

We’ve redesigned the bit shape, upgraded to tougher steel, and introduced patented button technology—resulting in a significantly longer service life.

Easy bit selection

Our streamlined bit range now covers all rock types with ~30% fewer options, making selection simpler and more versatile for any surface drilling job.

Longer grinding intervals

New button geometries and a special surface treatment mean fewer regrinds—delivering up to 15% more drilling per grind in most rock types.

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.

Protected by diamonds – a golden opportunity for you and the industry

When we launched the first generation of our PCD (polycrystalline diamond) drill bits, Powerbit X, we broke new ground. With the second generation, Epiroc PCD drill bits, we are crushing it.

And not only with an improved product that makes your operations more productive, safer, and more sustainable. 

It’s more than just that. It’s a statement. Built on our proud innovative heritage, we have developed and manufactured Epiroc PCD drill bits entirely inhouse. Why? Because we want to make these bits more accessible to the industry and frontrunners like you. You and this technology deserve it. 

Productivity - Faster drilling, straighter holes with consistent diameters, and drilling without time-consuming bit changes all boost your productivity.

Safety - With minimal changes, next-level automation and reduced traffic in the mine, your staff’s workdays are much safer.

Environment - The Epiroc PCD drill bits can cut the CO₂ equivalent contribution from drill bits by up to 90 % thanks to an improved life cycle performance, no regrinding, and fewer transports.
