Overview

MD5090 delivers high productivity by getting more holes drilled with fewer set ups. These fast cycle times are achieved thanks to its top performing rock drill, large pattern coverage, and a power group that’s ideally sized for drilling 89 mm-127 mm (3.5 in-5.0 in) holes. A non-cab, non-enclosure version, as shown, is lightweight and service accessible.
