MD6640 Rotary Drills

DESCRIPTION

The Cat® MD6640 Rotary 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 structure and easy serviceability, the MD6640 delivers long life. And it’s built for operators, with a number of features that enhance productivity and reduce fatigue. Designed to drill holes from 244-406 mm (9.6-16 in) in diameter, the MD6640 is is optimized for single-pass or multi-pass drilling in both rotary and down-the-hole drilling modes.The Cat® MD6640 Rotary 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.
