Rocketing rig ROI

Powerbit Underground is more than a new drill bit. It´s a way to boost the return on your rig investment - through increased drilling efficiency and reliability.
Boosts modern rigs...
Even the most powerful rig won’t do all the work by itself. You need a drill bit that matches the rig’s performance, withstanding the immense forces to give you more drill meters per day. Only then will you experience true drilling productivity.

...and older rigs too
Powerbit Underground gives older rigs a power boost too. It has more flushing holes and a smarter hole configuration than previous generations of bits. It will therefore increase the efficiency of rigs with lower water pressure and less effective flushing.

Faster, more reliable drilling
Powerbit Underground drills up to 15 percent faster than previous Epiroc models, reducing the total cost of ownership considerably.

Even so, the true gain comes from what Powerbit Underground will do to your availability and productivity. How about 20 percent more drill meters before the first regrind and 15 percent more drill meters between regrinds?

With this innovative bit, you will experience a whole new “flow” at work. Enjoying the satisfaction of trouble-free, uninterrupted drilling that spells more money in your pocket. All thanks to the bit’s extreme ruggedness.

Full utilization of your rig
Drill rigs get most of the attention in mining – and perhaps rightly so. After all, they do provide the necessary brute force. But smart miners also realize how to best make use of their rig’s full capacity.

Powerbit Underground allows you to complete more drill meters per day. Experience faster and more reliable drilling. Improve efficiency. Capitalize fully on your rig investment. All thanks to Powerbit Underground.

All is new!

PUG front view
Powerbit Underground may look like just another drill bit. It’s not. Everything about it is new. The steel it’s made of. The shape and design of its buttons. Its hole configuration. One factor just as important for your drilling efficiency as the other. Add all these benefits together, and you have the perfect recipe for successful drilling.
PUG steel
The steel
We put our metallurgists to work with a simple request – invent the most durable steel we’ve ever used in a drill bit (and our history dates back to 1873...) They came up with 15 percent higher wear resistance and 10 percent higher fatigue strength.
PUG face
The face
We put a lot of engineering into optimizing the bit’s face, since it is key to a high penetration rate. More flushing holes and a smarter hole configuration to maximize flushing efficiency and we paid special attention to make sure cuttings are removed as fast as possible.
PUG button
The buttons
The durability of the buttons is crucial to high drilling productivity. The Enduro Extra patented treatment, used on our spherical and Trubbnos buttons, makes them tougher and more wear resistant. For you, that means more drill meters between regrinds.

Trubbnos
The drillbit can be delivered with both spherical buttons and Trubbnos. Trubbnos is our new and innovative trapezoid-shaped buttons, which offer longer service life and improved penetration rate than semi-ballistic buttons. (Trubbnos, by the way, is Swedish for flat nose, an indication of the geometry of the new buttons.)

Unbeatable drill string

Every part of the drill string must perform optimally. That’s why we pay equal attention to shank adapters, drill rods, couplings and drill bits. For you, it means that you can get a complete, unbeatable drill string from a single supplier – Epiroc.
