Frequently Asked Questions

What is the difference between a dry grinder and a wet/dry grinder?

The dry grinder only has traditional abrasive wheels for fast grinding and roughing. The dry/wet combination has two wheels: one dry for roughing and one wet (with a cooling tray) for precision sharpening of cutting tools. The combined version costs 20-30% more but allows for precise sharpening without overheating the tool.

Is it better to resharpen drill bits or buy new ones?

A drill bit sharpener (€500-1,900) quickly pays for itself in professional workshops. A Ø10mm HSS drill bit costs €3-8, a Ø13mm drill bit costs €8-15. With 100-200 sharpened drill bits per year, you recover your investment. Properly sharpened drill bits cut like new. For hobbyists with occasional use, it's better to buy new drill bits.

Which grinding wheel diameter to choose: 150mm, 200mm, or 250mm?

Lifespan depends on usage and material. Occasional hobby use: 2-5 years. Medium professional use (2-3 hours/day): 6-18 months. Intensive industrial use: 3-6 months. Grinding wheels wear uniformly and should be periodically dressed with diamond dressers. Replacement wheel cost: €15-€40 for Ø150-200mm, €40-€80 for Ø250-300mm. Important: replace when diameter is reduced by more than 20%.

How long do abrasive wheels last?

Lifespan depends on usage and material. Occasional hobby use: 2-5 years. Medium professional use (2-3 hours/day): 6-18 months. Intensive industrial use: 3-6 months. Grinding wheels wear uniformly and should be periodically dressed with diamond dressers. Replacement wheel cost: €15-€40 for Ø150-200mm, €40-€80 for Ø250-300mm. Important: replace when diameter is reduced by more than 20%.

Is dust extraction needed for grinders?

Strongly recommended for professional use. Grinding produces fine metallic dust harmful to the respiratory tract and which settles everywhere. Many Bernardo grinders have a Ø100mm connection for a vacuum cleaner. A small vacuum cleaner (1,100W, €150) is sufficient for bench grinders. For workshops with multiple machines, a centralized system is advisable. Alternatively, at a minimum: an FFP2 mask and room ventilation.

Professional metal grinders for grinding, sharpening, and surface finishing of steels, cast irons, and metal alloys. Complete range from Bernardo and Flott for mechanical workshops, metal fabrication shops, and industrial maintenance departments.

Types of Grinders

Dry/Wet Combination Grinders - Dual function: dry grinding wheel for roughing and wet grinding wheel for precision sharpening. Integrated cooling troughs, 200-550W motors, ideal for tool sharpening and small jobs.

Double Bench Grinders - Two dry grinding wheels for intensive grinding. Diameters 200-400mm, motors up to 1,100W, cast iron structures for stability. For heavy fabrication and continuous production.

Drill Bit Sharpeners - Specialized machines for re-sharpening twist drills from Ø2mm to Ø32mm. Precise angles, adjustable guides, saving on new drill bits.

Industrial Surface Grinders - For large metal surfaces, micrometric precision. Magnetic tables, CNC systems. For mold making and precision mechanics.

Metal Sanders - Belt sanders and disc sanders for surface finishing, deburring, and weld preparation.

Main Applications

Ideal for sharpening cutting tools, grinding welded parts, removing burrs and oxidation, preparing surfaces for painting, sharpening drill bits and milling cutters, workshop equipment maintenance.
