Introducing Powerbit for ST58 and ST68 threads

7 de julio de 2017

En diciembre de 2015, Atlas Copco Secoroc presentó una nueva gama de brocas para perforación de superficie con martillo en cabeza: Powerbit. El primer sistema de rosca que llegó al mercado fue el T45. Desde su introducción, Powerbit T45 ha cumplido y superado todos los objetivos y expectativas. La vida útil se ha mejorado hasta en un 75 % y cuenta con una velocidad de penetración significativamente más alta.

Powerbit ST58 and ST68 for underground drilling

Now, we introduce Powerbit ST58 (89-115 mm) and ST68 (102-140 mm) for underground drilling. These ranges of bits have all the same characteristics that have made Powerbit T45 and T51 so successful. The bit shape is optimised. The bit body steel is harder and stronger. And the patented Enduro Extra button surface treatment technology and Trubbnos button shape, are developed for outstanding strength and wear resistance. On top of that, the ST thread and Powerbit ST58 and ST68 give you all the characteristics you need for long and straight holes. Some Powerbit ST58 and ST68 models are available with optional short guide wings. This minimises hole deviation and makes sure that the bit body wears at the same rate as the buttons, decreasing the risk for the bit to get stuck in the hole. Like all other Powerbits, the thread and undercut are optimised to reduce strain and minimise the risk for material fatigue. All in all, we expect Powerbit ST58 and ST68 to be every bit as effective as T45 and T51, which have proven to give exceptional performance in all types of rock.
