MEZ Series Hydraulic Hole Opener Lithium Electric Drilling Tool

This product is designed for on-site hole enlargement or new hole punching operations on metal sheets, electrical distribution boxes, cable trays, and similar materials. Utilizing a hydraulic boosting mechanism, it delivers more stable torque during hole enlargement—compared to purely motor-driven drilling—and is less prone to bit jamming. The straight-handle body design facilitates single-handed control over direction and downward pressure, thereby enhancing operational safety. Featuring a built-in rechargeable lithium battery, the unit requires no external power supply or hydraulic pump, making it ideal for use in the field or at job sites lacking access to mains electricity. The hydraulic stroke is precisely controlled by a motor, allowing for stepped adjustment of the hole diameter; the unit is compatible with dies for both round and oblong holes.
