The Pentruder MDU3 Core Drill Motor is a modular, high-performance drilling solution engineered to take core drilling to a new level — whether you’re tackling everyday service penetrations or the most demanding structural holes. Available in three variants (MDU3-30, MDU3-60 and MDU3-100) with drill bit capacities from 50 mm up to 1000 mm, the MDU3 family gives operators flexible drilling range and power in a single system. Its 8 kW water-cooled motor delivers strong output without the need for a separate powerpack, and the advanced integrated electronics and wide electronically variable spindle speed range make it easy to dial in the right performance for any bit size. Quick-disconnect drill bit couplings and a built-in display — showing spindle angle, amps, power, RPM and depth — add convenience and precision to the core drilling workflow.
