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 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%.
