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. In Krollit customers' laboratories, the MD 6050 VD is chosen by metal fabrication shops, 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 magnetic core drill range 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 standard repetitive operations 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 6050 VD has a higher capacity (Ø 60 mm) than the 5050 family. Lower speeds (100-440 rpm vs 100-810) consistent with the larger diameter: large tools require reduced speeds. MT 2 taper (vs Weldon on the 5050 models) for bulkier tools.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 business days (7 days to the South).
