Greatly improved service life

With Powerbit, our development engineers have looked at all aspects of drill bit technology to ensure the longest possible service life. The bit shape is all new. We've used harder and stronger bit body steel. And our new button technology is so effective that it's been patented many times over.


Easy bit selection

The Powerbit product range covers all types of rock - from hard to soft, and from abrasive to non-abrasive. Thorough research, simulation and testing have allowed us to make the Powerbit range much more compact and versatile than before. Approximately 30 % fewer bits now handle all tophammer surface drilling applications – making bit choice so much easier for you.


Longer grinding intervals

One of the most important development criteria for Powerbit was to improve service life and reduce the need for constant regrinds. The solution? New carbide button cutting geometries that offer maximum material on each button. What's more, each button has gone through a special surface treatment to make it tougher and more durable. For most rock formations we offer you up to 15 % more meters between regrinds.


Bits for surface drilling

   

Rocket bit

Full-ballistic buttons

The best choice for soft rock conditions. Full-ballistic buttons and large vertical flushing grooves effectively remove larger chips, greatly increasing penetration rate.

Powerface bit

Trubbnos buttons, heavy duty (HD)

Ideal for abrasive, medium hard to hard rock. Larger Trubbnos (trapeziod shaped) buttons and flushing grooves give the ideal balance between service life and penetration rate. Available with a short retrac for straight holes in broken rock.

Powerface bit

Trubbnos buttons

Designed for medium hard to hard rock. Trubbnos (trapeziod shaped) buttons provide better penetration rate than spherical buttons, and a longer service life than semi-ballistic ones. Available with a short retrac for straight holes in broken rock.

Powerface bit

Spherical buttons, heavy duty (HD)

For tough conditions in hard and abrasive rock. Optimised face and body design and large spherical buttons for long service life. Available with a short retrac for straight holes in broken rock.

Flatface bit

Spherical buttons

Ideal for hard, medium abrasive rock. The flat face, with many spherical buttons, offer an optimised energy transfer. Available with a short retrac for straight holes in broken rock.
