Güde GBS 80 Drill Bit Sharpener – 3–13 mm, 118° angle, 80 W
The GBS 80 sharpener is specialised equipment for precision workshops that require drill bits to always remain sharp. It maintains drill bits from 3 to 13 mm with a 118° angle – the international standard for ferromagnetic materials such as steel, iron and alloys. The automatic chuck with alignment device ensures precise and repeatable sharpening without positioning errors.
Unlike manual sharpening on a grinding wheel, which is risky, imprecise and dependent on the operator’s skill, the GBS 80 automates the process: place the drill bit in the chuck, activate the alignment button, and the machine sharpens the angle correctly. Average time per drill bit: 30–45 seconds. Result: drill bits always cut perfectly, reducing drilling times and stress on the drill.
Distinctive features:
- Drill bit diameter 3–13 mm – Full coverage of the standard workshop range, from small bits for precision work to larger bits for quick holes in soft metals
- 118° angle – International standard for steel, iron and alloys. Not suitable for special materials, as titanium and composites require different angles
- Automatic chuck – Precise drill bit positioning. The alignment device ensures the correct geometry every time
- 80 W motor, 4200 rpm – Suitable speed for efficient abrasion without overheating. Protection class I, S3 20% operating mode, intermittent and not for continuous cycles
- Lightweight 2.7 kg design – Easy to place on a workshop bench. Compact dimensions, 225 × 185 × 155 mm, do not take up excessive workspace
- Aluminium frame, plastic body – Lightweight and robust. Resistant to impacts and vibrations from repeated cycles
- CE + Q9 certifications – European safety compliance. Güde German quality standard
Who chooses it in Italy
Precision mechanical workshops – Metal fabrication shops, turning workshops and companies that perform frequent drilling, 100+ holes/week. Always-sharp drill bits mean reduced cycle times, better hole quality and less stress on drills.
Metalworking specialists – Blacksmiths and craftspeople working with steel and iron. Fast and precise sharpening enables efficient work cycles without interruptions to find a specialist sharpening service.
Service and maintenance centres – Mechanical service companies that recondition tools. The GBS 80 is a basic tool for maintaining and regenerating used drill bits.

Who the GBS 80 is suitable for
| Profile |
Suitable? |
Reason |
| Precision workshop / metal fabrication shop |
Ideal |
Fast and precise sharpening of 3–13 mm drill bits is a standard requirement for frequent drilling cycles. Reduces time, improves quality and preserves drills |
| Metalworking craftsperson, lathe or milling machine user |
Ideal |
Sharp drill bits are essential for work precision. The GBS 80 allows quick on-site reconditioning without relying on external services |
| Hobby users and small craftspeople |
Suitable |
For occasional drilling cycles, under 20 holes/week, the investment is not a priority. Manual sharpening on a grinding wheel is a cheaper option |
Not suitable for: Occasional hobby users, one hole every now and then; light metalwork where drill bit quality is not critical; professionals who outsource sharpening to specialists; sharpening requirements with non-standard angles, as titanium and composites require 120° or 140° angles – the GBS 80 is fixed at 118°.

Frequently asked questions
What is the maximum drill bit diameter the GBS 80 can sharpen?
13 mm is the maximum diameter. The range sharpens drill bits from 3 to 13 mm, covering all standard workshop drill bits, from precision drilling to quick holes. Drill bits with diameter >13 mm must be sharpened using a different method, such as a bench grinder or specialist services.
What is the sharpening angle of the GBS 80?
118° 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.
How long does it take to sharpen a single drill bit?
Average time: 30–45 seconds per drill bit, 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.
Is the GBS 80 suitable for sharpening carbide drill bits instead of high-speed steel?
No, 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.
What is the wheel speed and why is it important?
The motor speed of 4200 rpm 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.
What is the difference between manual sharpening and automatic sharpening with the GBS 80?
Manual: 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. Automatic, with GBS 80: 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.
Can the GBS 80 be used continuously without breaks?
No, 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.
What maintenance is required for the GBS 80?
Minimal: monthly inspection and cleaning of the wheel, abrasive dust removal, checking chuck clamping and button operation. Periodic spare parts: 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.
