Sandvik introduces Autobit, first drill bit for automated drilling

Automated drill rigs transformed the industry more than two decades ago, but even today few are used to their full potential due to drill bits that wear out and limit production. The new Autobit from Sandvik Mining and Rock Solutions seeks to help customers change that through long grinding intervals, enabling drilling to continue during shift changes.

Autobit is the first drill bit from Sandvik designed specifically for automated longhole drilling. It features a greatly increased first grinding interval - more than twice that of standard bits – that can translate to several more hours of drilling every day. This is made possible thanks to a new and innovative bit design and the addition of Sandvik’s PowerCarbide™, the most powerful carbide grade.

“Autobit addresses a key bottleneck in the automated drilling process: running the drill rig during shift changes,” said Robert Grandin, Product Manager Top Hammer Underground at Sandvik Mining and Rock Solutions. “The Autobit now enables customers to significantly increase productivity in their automated drilling operations.”

The longer service life and grinding intervals are made possible through the new design features of Autobit, combining a strong gauge row, fully ballistic button profile and carved out front design, as well as the addition of the PowerCarbide™ SH70 grade, part of Sandvik’s most innovative carbide technology. Together with the Autobit’s design elements, the self-hardening carbide grade can more than double grinding intervals compared to a standard product.

“Combining our PowerCarbide™ technology with a bit design that maximizes the first grinding interval delivers remarkable outcomes,” Grandin said. “Test results, where grinding intervals are more than doubled compared to standard products in automated conditions, really show how Autobit improves productivity.”

The 4-inch Autobit is available from stock today with more diameters arriving soon.
