Machine with 2-speed transmission (230 \/ 550 rpm): the low gear provides high torque for large diameter core drilling, the high gear for faster drilling. The electromagnet with 12,800 N adhesion force ensures secure fastening on steel structures even in vertical or overhead positions, with a safety belt\/chain included as standard. The automatic internal lubrication system brings coolant directly to the tool through the spindle, significantly extending the life of core drills (expensive consumables) and improving hole quality. Its 18 kg weight and compact dimensions (270 × 300 × 625 mm) make it transportable to construction sites in a case or plastic container, without the need for pallet jacks or cranes. In Krollit customer workshops, the MD 5075 is chosen by metal fabricators, automotive workshops, steel structure manufacturers, industrial maintenance technicians, and on-site installers.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo magnetic core drilling machine range is organized by core drilling capacity (max diameter and depth) and drive type.
