Epiroc introduced a new assortment of bolting bits that are designed to enhance efficiency and reliability in rock drilling operations.
With innovations such as the Trubbnos button technology, Epiroc says its new tools deliver a longer service life, a higher rate of penetration and a lower total cost of ownership.
As Epiroc describes, the Trubbnos button design features a distinctive trapezoid shape providing a larger rock contact surface and greater wear volume compared to traditional semi-ballistic buttons. This translates to longer intervals between regrinds while maintaining consistent drilling performance, according to the company.
“Our new bolting bits deliver practical benefits that align with the needs of our customers,” says Fredrik Gransell, head of product marketing for top hammer drilling tools at Epiroc. “They are built to improve productivity while reducing operational costs, making them an excellent choice for demanding applications.”
The new rock drilling tools feature a strengthened steel bit body with higher fatigue resistance, as well as advanced carbide grades for improved wear resistance. The redesigned flushing system further enhances performance by reducing wear and ensuring smoother drilling operations.
Epiroc’s new bolting tools are available for S and SR drill strings.
