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.
- 13% more bit load on average than other drills this size*
- Performs in harsh environments — under -30 °C, over 4,500 meters or altitude`
- 68,040 kgs bit loading (150,000 lbs.), 34,040 NM torque — breakthrough power for tough rock conditions found around the world
- [FOOTNOTE]*Based on competitive analysis of advertised bit loads of leading manufacturers
