The reliability you need for the productivity you demand

Designed with the reliability and productivity you need in mind, the 320XPC blasthole drill is a robust electric-platform-style drill engineered for challenging drilling in tough rock. It has a solid record of performing in harsh conditions — arctic, high-altitude and hard rock applications. An excellent choice to help you achieve your production goals with powerful pulldown and propulsion capabilities.

Features may include:

Powerful pulldown
  • Built for availability. Positive bit loading with an electric top-drive rack-and-pinion pulldown means a reduction in wearing components. This feature also offers a robust and precise way to transmit the pulldown force into the bit.
Rugged masts
  • Drill masts must tolerate high loads, so we used finite element analysis to achieve high-cycle fatigue-resistant structures and control downtime and costs due to repairing cracks. Constructed of standard high-strength alloy steel, the mast provides robust rotary carriage and drill string support.
Superior propulsion
  • Built for durability with mainframes and crawler frames that can stand up to your hard-rock mine conditions. Rugged crawlers and powerful hydrostatic propel drives deliver maneuverability, gradeability and fast set-ups.
Ample, reliable air compressors
  • Ample, reliable air compressors
Superior operator visibility
  • Operators have a wide view of drilling and surrounding areas with windows and video technology to help them maintain situational awareness while drilling and propelling. The operator's chair swivels to face the direction of travel during propelling for ease of repositioning.
