Sandvik Top Hammer Autobit is designed to enhance automated operations in longhole/production drilling. It has a long first grinding interval, more than twice that of standard bits, to last through an entire shift change.
Autobit comes with a new, innovative bit design, which combines a strong gauge row, fully ballistic button profile and carved-out front design.
The new bit design together with PowerCarbide® SH70 grade greatly increases productivity in automated longhole drilling operations. Your first grinding interval can be more than doubled, leading to extensively prolonged drilling in auto.
PowerCarbide® grades is wear resistant, which helps to extend the first grinding intervals. A longer bit life is more cost-effective, environmentally-friendly and means fewer changes, less manual handling and reduced risk of injury.
