The Holzmann magnetic drilling machine for core drilling and tapping is ideal for machining large, immobile steel workpieces - wherever conventional drilling machines and cordless screwdrivers reach their limits. The machine enables mobile processing of workpieces with precise guidance and is effective and accurate even when drilling vertical holes. By activating the electromagnet, the drill can be attached to any steel part and in any position. No slipping, as the magnet provides safety when working overhead. It is often used in the construction industry, bridge building and shipbuilding.
