Epiroc ET drill string mounting bit on tube.tif

Product description

Maximizing mine uptime is crucial for continuous production and revenue. The ET drill strings, based on a high-precision tube-drilling system from Epiroc, enhance durability and efficiency for the drill rig's vital component – the drill string.

 

Perfectly integrated with other equipment, it ensures smooth production, minimizing standstills and unplanned maintenance. Our equipment reliability brings peace of mind to operators, supervisors, maintenance personnel, and mine planners, influencing efficiency and sustainability. A smoothly operating drill rig significantly accelerates ore recovery, reduces maintenance costs, and establishes predictable production schedules.

 

In other words, the Epiroc ET drill strings not only result in increased productivity for your business – but also better workdays for you and your colleagues.

 

Maximized utilization rate

Fewer failures and accidents due to less damage to the equipment in combination with significantly increased service life, leading to higher productivity.

 

Ease of use

Easy to employ with similar param­eter settings as previous, easy uncoupling, easy service planning.

 

Increased profitability

The new ET drill strings provides unparalleled bending endurance, ensuring optimal hole straightness and long service life.

 

Enjoy your uptime.

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.

TECHNICAL DATA  
Main application area  Underground production drilling
Bit diameter 75 mm - 114 mm
Button shape Spherical
Rock conditions Hard

Epiroc underground bits

Powerbit Underground PUG

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.

TECHNICAL DATA  
Main application area  Underground production drilling, tunneling
Bit diameter 66 mm - 203 mm
Button shape Ballistic, spherical and trubbnos
Rock conditions Hard, medium hard

Epiroc surface bits

Powerbits T45 and rod.

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.
