Polishing disc Proxxon 28 310 — abrasive accessory for rotary tools

Proxxon 28 310 is a polishing disc designed as an abrasive accessory for rotary and bench polishing tools. Engineered to deliver controlled material removal and surface refinement, the disc is suitable for finishing metal, wood, plastics and composite materials. The disc combines a soft compound with silicon carbide abrasive to provide consistent polishing performance on very hard materials when used with a rotary polishing attachment featuring a 12.7 mm bore.

Advantages

The disc’s silicon carbide grit offers effective cutting action on hard surfaces while the soft backing compound ensures conformability and reduced risk of gouging. A 12.7 mm bore allows secure mounting on standard rotary arbors, enabling stable operation and predictable surface results. The product balances abrasive aggressiveness with fine finishing ability to support both material removal and smoothing in one accessory.

Suitable for

• Polishing and finishing metal components
• Smoothing and refining plastic and composite surfaces
• Light stock removal and surface preparation prior to coating or painting
• Detail work on small parts using rotary tools or bench polishers

Key specifications

• Abrasive type: silicon carbide
• Backing/compound: soft compound for conformability
• Bore diameter: 12.7 mm for standard rotary mounting
• Intended material hardness: optimized for very hard materials
• Typical use: polishing, finishing, light material removal

How to use

Secure the polishing disc on a compatible rotary tool or bench polisher using an arbor that matches the 12.7 mm bore. Start at a low rotational speed to check contact and work progressively up to the recommended speed for your tool and material. Apply light, even pressure and keep the disc moving to avoid overheating or local overcutting. For best results, inspect the surface frequently and finish with finer abrasives or a polishing compound if a higher gloss is required.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, gloves and a dust mask when working with abrasive discs. Match abrasive aggressiveness to the material and begin with a test area to determine optimal speed and pressure. Avoid excessive heat build-up by using intermittent contact and allow the workpiece to cool between passes.
