In a mechanical workshop that drills regularly, drill bits are among the most frequent consumables: an HSS drill bit of Ø 10 mm costs 3–8 euros; sharpening it with the DG 32 MD takes 20–40 seconds. At 30 kg and single-phase 230V, it can be installed on any workbench without additional equipment. In Krollit customers' workshops, it is used by mechanical workshops, metalworking shops, and maintenance laboratories.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Bernardo DG 32 MD for\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eProfile\u003c\/th\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003cth\u003eReason\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePassionate hobbyist\u003c\/td\u003e\n\u003ctd\u003eSuitable\u003c\/td\u003e\n\u003ctd\u003e30 kg, 230V: adequate for advanced hobbyists with significant drill bit consumption.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProfessional mechanical workshop\u003c\/td\u003e\n\u003ctd\u003eIdeal\u003c\/td\u003e\n\u003ctd\u003eØ 12–32 mm range: restores the most used drill bits in the workshop with an ROI measurable in weeks.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntense industrial production\u003c\/td\u003e\n\u003ctd\u003eAdequate\u003c\/td\u003e\n\u003ctd\u003eFor very high volumes, consider automatic sharpeners.
