Diamond grinding wheel Proxxon 50 x 1.7 x 9.6 mm — abrasive wheel for precision grinding

Diamond grinding wheel Proxxon 50 x 1.7 x 9.6 mm is a thin, diamond-coated abrasive wheel engineered for precision grinding and fine cutting operations. Its compact dimensions and narrow profile allow controlled material removal on small workpieces and tight radii. The wheel is suitable for use on rotary tools and small bench grinders that accept a 9.6 mm bore and the specified diameter and thickness, providing consistent abrasive performance on hard materials.

Advantages

The diamond coating delivers high hardness and long wear life compared with conventional abrasives, enabling effective grinding of ceramics, hardened steels, carbide, glass and gemstones. The thin 1.7 mm thickness reduces the contact area for precise trimming and minimal material loss, while the small 50 mm diameter improves accessibility in confined areas. Balanced construction minimizes vibration for smoother finishes and improved control during fine grinding tasks.

Suitable for

• Precision tool sharpening and edge refinement
• Model making and miniature shaping
• Jewellery finishing and gemstone trimming
• Grinding and trimming of ceramics, glass and carbide parts
• Fine deburring and slot cutting on small components

Key specifications

• Diameter: 50 mm
• Thickness: 1.7 mm
• Bore diameter: 9.6 mm
• Abrasive type: diamond-coated surface
• Profile: thin, narrow abrasive wheel for precision work

How to use

Mount the diamond wheel on a compatible rotary tool or bench grinder that accepts a 9.6 mm arbor. Ensure the tool is powered off and disconnected before fitting. Use appropriate wheel flanges and secure fastenings to maintain concentricity. Operate at the manufacturer’s recommended speed for diamond abrasive wheels; avoid excessive side pressure—let the abrasive do the cutting. Maintain steady, light passes to achieve accurate material removal and prevent overheating. After use, inspect the wheel for wear or damage and replace if the diamond layer is compromised.

Usage recommendations

For best results, use personal protective equipment including eye protection and appropriate respiratory protection when grinding dust-producing materials. Coolant or intermittent contact can reduce heat build-up when working on heat-sensitive materials. Verify compatibility of the wheel with your grinder’s maximum RPM and use the correct flanges for safe, vibration-free operation.
