Designed with safety in mind
Meets worldwide standards including Mining Design Guidelines (MDG) for mobile and transportable equipment in mines, Earth Moving Equipment Safety Round Table (EMESRT) design philosophies, ISO 3449 Level II and CE conformity marking.
Heavy duty chain feed system
Hydraulic cylinder driven heavy duty chain feed system produces higher pulldown and increased weight on bit resulting in higher penetration rates in hard rock applications.
Compressor management
Advanced compressor management reduces the load by controlling air volume to maximize efficiency and reduce fuel burn, decreasing your carbon footprint and extending engine and compressor life.
Precision-drilled holes
The scalable iDrill automation platform unlocks automation options and digital services to provide clean, precision-drilled holes, maximizing fragmentation and asset utilization.
DRi Control system
Common control system provides a consistent operating experience and improved control of rig functions across all iSeries surface rotary drills.
Operator comfort and control
Operators receive an unobstructed view of the drill table from a raised, swivel-enabled chair with integrated touchscreens and keypads. Large, angled windows reduce glare and a safari-style roof keeps the cab cooler.
