Thinning reduces the web thickness of the drill bit, improving centering on the workpiece and reducing the feed force required during drilling. This feature, rare in sharpeners of this range, distinguishes the DG 13 MD from the basic DG 13 M. The CBN (cubic boron nitride) grinding wheel is the correct technical choice for sharpening HSS and carbide. In Krollit's customer workshops, it is chosen by mechanical workshops, maintenance departments, and precision mechanics who want to reduce drill bit replacement costs and improve drilling performance on steels and metals.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe DG 13 MD is the superior version of the DG 13 M in the Bernardo drill bit sharpener range.

Above the DG 13 MD in the Bernardo range are sharpeners for milling cutters (EMG 30, EMG 60) and universal sharpeners, sized for other types of tools.

In Krollit's customer workshops, it is used by mechanical workshops, metal fabricators, and maintenance labs.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Bernardo DG 20 M 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\u003eIdeal\u003c\/td\u003e\n\u003ctd\u003eCompact, economical, 230V: the entry point into drill bit sharpening for those who want to stop throwing them away.\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 2–20 mm range: reconditions the most used drill bits in the workshop with a measurable ROI in weeks.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntensive industrial production\u003c\/td\u003e\n\u003ctd\u003eAdequate\u003c\/td\u003e\n\u003ctd\u003eFor very high volumes, consider automatic sharpeners.

sharpen?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e13 mm\u003c\/strong\u003e is the maximum diameter. The range sharpens drill bits from \u003cstrong\u003e3 to 13 mm\u003c\/strong\u003e, covering all standard workshop drill bits, from precision drilling to quick holes. Drill bits with diameter \u0026gt;13 mm must be sharpened using a different method, such as a bench grinder or specialist services.\u003c\/p\u003e\n\u003ch3\u003eWhat is the sharpening angle of the GBS 80?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e118°\u003c\/strong\u003e is the fixed sharpening angle. This is the international standard for ferromagnetic materials: steel, iron and iron alloys. The angle cannot be changed – the GBS 80 cannot be configured for different angles. Special materials, such as titanium at 135° and composites at 120°, require dedicated sharpeners.\u003c\/p\u003e\n\u003ch3\u003eHow long does it take to sharpen a single drill bit?\u003c\/h3\u003e\n\u003cp\u003eAverage time: \u003cstrong\u003e30–45 seconds per drill bit\u003c\/strong\u003e, including positioning in the chuck and activating the alignment device. Total time depends on operator experience and wheel wear. Manual sharpening on a grinding wheel requires 2–5 minutes per drill bit and is riskier and less precise.\u003c\/p\u003e\n\u003ch3\u003eIs the GBS 80 suitable for sharpening carbide drill bits instead of high-speed steel?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eNo\u003c\/strong\u003e, the GBS 80 is designed for high-speed steel (HSS) and ferromagnetic materials. Carbide drill bits require specialised diamond wheels and dedicated equipment – they are not sharpened on standard abrasive wheels. Contact Güde or a specialist centre for carbide drill bits.\u003c\/p\u003e\n\u003ch3\u003eWhat is the wheel speed and why is it important?\u003c\/h3\u003e\n\u003cp\u003eThe motor speed of \u003cstrong\u003e4200 rpm\u003c\/strong\u003e is suitable for efficient abrasion on high-speed steel without overheating. Too low a speed means slow and imprecise sharpening; too high a speed risks burning the drill bit and losing temper. 4200 rpm is the optimal compromise for the 80 W category.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between manual sharpening and automatic sharpening with the GBS 80?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eManual\u003c\/strong\u003e: the operator positions the drill bit on the grinding wheel by hand – risk of angle error, imprecise result, dependent on skill, long times, 2–5 min\/bit, and injury risk. \u003cstrong\u003eAutomatic, with GBS 80\u003c\/strong\u003e: the chuck positions the drill bit automatically, the alignment device forces the correct geometry, times are short, 30–45 sec, repeatability is precise and operational safety is higher. The investment in automation is recovered through speed and quality.\u003c\/p\u003e\n\u003ch3\u003eCan the GBS 80 be used continuously without breaks?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eNo\u003c\/strong\u003e, the operating mode is S3 20%, intermittent, 20% duty cycle. This means a maximum of 12 minutes of continuous operation per hour. It is not designed for continuous production cycles – it is equipment for occasional sharpening in the workshop. For continuous industrial cycles, contact Güde for professional models.\u003c\/p\u003e\n\u003ch3\u003eWhat maintenance is required for the GBS 80?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMinimal\u003c\/strong\u003e: monthly inspection and cleaning of the wheel, abrasive dust removal, checking chuck clamping and button operation. \u003cstrong\u003ePeriodic spare parts\u003c\/strong\u003e: carbon brushes every 200–300 hours, depending on frequency of use, and abrasive wheel every 6–12 months with intensive use. No special lubrication is required – the motor is sealed.\u003c\/p\u003e","brand":"Guede","offers":[{"title":"Default Title","offer_id":53106806194504,"sku":"94066","price":63.68,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Affilatrice_per_punte_da_trapano_G_de_GBS_80_3-13_mm_angolo_118_mandrino_automatico.jpg?v=1778850751"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/collections\/Progetto_senza_titolo_-_2025-09-24T175720.175.png?v=1758729463","url":"https:\/\/www.krollit.com\/collections\/sharpeners-for-drill-bits-from-drill.oembed","provider":"Krollit","version":"1.0","type":"link"}
