Fixed speed 810 rpm: simple and reliable configuration for standard use on typical materials and diameters. For workshops that primarily work structural steel with standard core drills, the fixed speed is correctly sized, avoiding electronic complexity and the costs of an inverter. The electromagnet with 16,000 N adhesion force ensures secure fastening on steel structures even in vertical or overhead positions, with a safety belt\/chain included as standard. Its 11 kg weight and compact dimensions (170 × 280 × 400 mm) make it transportable to construction sites in a case or plastic container, without the need for pallet jacks or cranes. In Krollit customers' workshops, the MD 3550 E is chosen by metal fabricators, automotive workshops, steel structure manufacturers, industrial maintenance personnel, and on-site installers.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo magnetic core drill range is organized by core drilling capacity (max diameter and depth) and by drive type.

Continuously variable speed 100 – 830 rpm: the 'VD' in the name indicates 'Variable Drive', the electronic system that allows selecting the optimal speed for each tool-material combination. For hard steels, low speeds (100-200 rpm), for standard steels 300-500 rpm, for soft materials higher speeds. A useful feature in workshops with a variety of operations and materials. The electromagnet with 14,800 N adhesion force ensures secure fastening to steel structures even in vertical or overhead positions, with a safety belt\/chain supplied as standard.

Its 11 kg weight and compact dimensions (150 × 280 × 430 mm) make it transportable to construction sites in a case or plastic container, without the need for a pallet jack or crane. In Krollit customer labs, the MD 3550 VD is chosen by metal fabricators, automotive workshops, steel structure manufacturers, industrial maintainers, and on-site installers.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo magnetic core drill range is organized by core drilling capacity (max diameter and depth) and drive type.

Fixed speed 480 rpm: simple and reliable configuration for standard use on typical materials and diameters. For workshops that primarily work with structural steel using standard core drills, the fixed speed is correctly sized, avoiding the electronic complexity and cost of an inverter. The electromagnet with 10,500 N adhesive 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 delivers coolant directly to the tool through the spindle, significantly extending the life of core drills (expensive consumables) and improving hole quality. Its 12.7 kg weight and compact dimensions (240 × 255 × 500 mm) make it portable to construction sites in a case or plastic container, without the need for pallet jacks or cranes. Among Krollit's customers, the MD 4055 is chosen by metal fabrication workshops, automotive workshops, steel structure manufacturers, industrial maintenance technicians, and site installers.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo range of magnetic drilling machines is organized by core drilling capacity (max diameter and depth) and drive type. The range includes 10 models divided into 3 families:\n\nE Family (fixed speed): MD 3550 E (Ø 35 mm), MD 3850 (Ø 38 mm), MD 4055 (Ø 40 mm), MD 5050 E (Ø 50 mm). Suitable for workshops with repetitive standard work on known materials.\n\nVD Family (Variable Digital Speed): MD 3550 VD (Ø 35 mm), MD 5050 VD (Ø 50 mm), MD 6050 VD (Ø 60 mm), MD 9875 VD (Ø 98 mm). Continuously adjustable speed for material adaptation, suitable for workshops with a variety of operations.\n\nM Family (multi-gear\/multifunction): MD 5075 with 2 gears (Ø 50 mm × 75 mm depth), TPC 1000 multifunction with tapping up to M18.\n\nThe MD 4055 is sized for workshops with standard daily use. For workshops that alternate different materials (mild steels, hardened steels, aluminum), the corresponding VD version offers greater flexibility: for the MD 4055, the equivalent VD is the superior VD range.

Continuously adjustable speed for adaptation to the material, suitable for workshops with a variety of operations.\n\nM family (multi-gear\/multifunction): MD 5075 with 2 gears (Ø 50 mm × 75 mm depth), TPC 1000 multifunction with tapping up to M18.\n\nThe MD 5050 E is sized for workshops with standard daily use. For workshops that alternate different materials (mild steels, hardened steels, aluminum), the corresponding VD version offers greater flexibility: for the MD 5050 E, the equivalent VD is the MD 5050 VD.

Continuously variable speed 100 – 810 rpm: the 'VD' in the name indicates 'Variable Drive', the electronic system that allows selecting the optimal speed for each tool-material combination. Low speeds (100-200 rpm) for hard steels, 300-500 rpm for standard steels, higher speeds for soft materials. A useful feature in workshops with a variety of machining operations and materials. The electromagnet with an adhesion force of 15,600 N ensures secure fastening on steel structures even in vertical or overhead positions, with a safety belt\/chain supplied as standard. The automatic internal lubrication system brings the coolant directly to the tool through the spindle, significantly extending the life of core drills (expensive consumables) and improving hole quality. Its 11.2 kg weight and compact dimensions (150 × 280 × 430 mm) make it transportable to the construction site in a case or plastic container, without the need for a pallet truck or crane.

Continuously variable speed 100 – 440 rpm: the 'VD' in the name indicates 'Variable Drive', the electronic system that allows selecting the optimal speed for each tool-material combination. For hard steels, low speeds (100-200 rpm), for standard steels 300-500 rpm, for soft materials higher speeds. A useful feature in workshops with a variety of machining operations and materials. The electromagnet with 16,000 N adhesion force ensures secure attachment to steel structures even in vertical or overhead positions, with a safety belt\/chain provided as standard. The automatic internal lubrication system delivers coolant directly to the tool through the spindle, significantly extending the life of core drills (expensive consumables) and improving hole quality. Its 17 kg weight and compact dimensions (200 × 320 × 500 mm) make it transportable to the job site in a carrying case or plastic container, without the need for pallet jacks or cranes.

Continuously variable speed 100 – 340 rpm: the 'VD' in the name stands for 'Variable Drive', the electronic system that allows selecting the optimal speed for each tool-material combination. For hard steels, low speeds (100-200 rpm), for standard steels 300-500 rpm, for soft materials, higher speeds. A useful feature in workshops with a variety of processes and materials. The electromagnet with 17,000 N adhesive 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 delivers coolant directly to the tool through the spindle, significantly extending the life of core drills (expensive consumables) and improving hole quality. The 17.5 kg weight and compact dimensions (250 × 320 × 500 mm) make it portable to the construction site in a case or plastic container, without the need for a pallet jack or crane.

For working on aluminum or non-magnetic stainless steel, fixed column drills or dedicated mechanical clamping systems are needed.

The 19 mm Weldon is the international standard for core drills: most commercial drills (Karnasch, Magbohrer, Rotabroach, BDS, etc.) use this holder. The drills all have a 19 mm Weldon shank for quick fastening via a side set screw.\u003c\/p\u003e\n\u003cp\u003eFor workshops with drills of other brands or standards, adapters can be used.

For workshops with significant electricity costs, consumption is negligible.
