2023 Komatsu Blasthole drills 320XPC

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.
