Diamond Cutting Disc Proxxon PR28012 — 50 mm Ø, 10 mm bore

Diamond cutting disc Proxxon PR28012 — 50 mm Ø, 10 mm bore is a compact diamond-edged wheel designed for precise trimming, shaping and cutting of hard materials. With a 50 mm outer diameter and a fine cutting rim, the disc is intended for use with compatible rotary tools and small saws. It provides a durable cutting surface suitable for controlled, small-scale operations on ceramics, glass, natural stone and similar materials.

Advantages

The diamond cutting disc offers a long-lasting diamond cutting edge that maintains cutting performance during repeated use. Its small 50 mm diameter and 10 mm bore enable accurate handling in tight spaces and on detailed workpieces. The product is engineered for smooth cuts with minimal chipping when used at recommended speeds and with appropriate cooling or lubrication. Compatibility with common rotary tool fittings ensures simple mounting and stable operation.

Suitable for

• Cutting and trimming ceramic tiles and porcelain
• Shaping and cutting glass in small craft projects
• Detail work on natural stone, marble and slate
• Fine removal and trimming in model making and restoration

Key specifications

• Outer diameter: 50 mm
• Bore diameter: 10 mm
• Cutting edge: diamond grit
• Type: thin cutting disc for rotary tools and small saws
• Typical applications: cutting, trimming and shaping hard brittle materials

How to use

Mount the disc on a compatible rotary tool or small saw with a matching 10 mm arbor. Ensure the disc is securely fastened and rotates freely before starting the tool. Work at steady, moderate feed rates and avoid forcing the disc into the material; let the diamond edge do the cutting. For best results on ceramics, glass or stone, use light pressure and, where applicable, apply intermittent cutting to avoid overheating. Use an appropriate cutting speed recommended by your rotary tool manufacturer.

Usage recommendations

Use protective equipment such as safety glasses, dust mask and gloves. When cutting brittle materials, consider wet cooling or periodic spraying of water to reduce dust and extend disc life. Inspect the disc before each use for cracks or damage and replace if any defects are found. Maintain stable mounting and avoid excessive lateral pressure to ensure straight, clean cuts.
