MD6640

Rotary Drills

The Cat® MD6640 Rotary Blasthole Drill is the only electric-drive drill in the Cat family but it shares the same characteristics of performance, reliability and durability with the rest of the drills in the Cat lineup. Ideal for harsh environmental conditions, the MD6640’s industry-leading durability is driven by its excavator-style undercarriage. Thanks to rebuildable components, superior structures and easy serviceability, the MD6640 delivers proven performance and long life. And it’s built for operators, with a number of features that enhance productivity and reduce fatigue. Designed to drill holes from 270-406 mm (10.625 -16 in) in diameter, the MD6640 is optimized for single-pass or multi-pass drilling for large borehole applications in hard rock.
