Powerbit is the all new range of tophammer drill bits for surface drilling from Epiroc. They’re 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 Powerbit, drillers are guaranteed to get more performance from each bit.
*Some bits within the Powerbit assortment can also be used for underground drilling. The Powerbit range for ST58 and ST68 is only for underground drilling applications.
Powerbits are available for the thread systems T35, T38, T45, T51, T-WiZ60, ST58 and ST68. Tests have been performed all over the world in a great variety of rock conditions. The results? Powerbit greatly outperforms all competing bits. Depending on rock type, service life is up to 75 % better than the competition. And penetration rate is up to 10 % better.
The Powerbit range gives you an unbeatable drill string, where our shank adapters and drill rods are already known to be top-of-the-line. Welcome to the tophammer world of Epiroc Drilling Tools.
Our semi-ballistic cemented carbide buttons are exchanged for buttons with a patented Trubbnos (trapeziod) shape. These buttons have a greatly improved wear resistance and give the drillers much longer intervals between regrinds.
Trubbnos and spherical buttons feature our patented Enduro Extra treatment. This results in buttons that get a harder and tougher surface, improving drilling performance, and reducing the risk for insert breakage.
