Polishing accessory set Proxxon 28985 – polishing supplies for rotary tools

Proxxon 28985 is a compact polishing accessory set designed for precision finishing with standard rotary tools. The set centers on a conformable flapwheel that adapts to flat and contoured surfaces as well as internal curves in round workpieces. Intended for final-stage polishing after heavier sanding or material removal, the accessories deliver controlled abrasion and a consistent surface finish on metals, plastics and similar materials. The shank fits typical mini- and micro-drill chucks, making the kit suitable for workshop and hobby applications that require careful surface refinement.

Advantages

The flapwheel’s flexible construction allows it to follow complex shapes and edges without creating sharp transitions or gouges. A medium 120 grit provides effective material smoothing and prepares surfaces for subsequent finer polishing steps. The small-diameter shank ensures secure mounting in rotary tool collets and supports precise control during detailed work. The single-piece format is convenient for quick replacement and targeted finishing tasks.

Suitable for

• Final sanding and finishing of metal components
• Polishing plastic parts and molded surfaces
• Detail work inside cylindrical or curved workpieces
• Model making, jewelry refinishing and small-scale workshop projects

Key specifications

• Shank diameter: 3 mm (7/64")
• Abrasive grit: 120 (medium)
• Flapwheel diameter: 1-3/16" (approx. 30 mm)
• Flapwheel height: 13/32" (approx. 10 mm)
• Quantity: 1 piece

How to use

Install the flapwheel firmly into the rotary tool collet or chuck rated for a 3 mm shank. Run the tool at a moderate speed suitable for the material being worked; start with lower rpm to verify contact and increase as needed for smoother removal. Apply light, even pressure and move the accessory across the surface in steady passes, allowing the flapwheel to conform to curves and edges. After finishing, inspect the surface and, if required, follow with finer abrasives or polishing compounds for a higher gloss.

Usage recommendations

Use appropriate eye and respiratory protection during grinding and polishing. Test on a scrap piece to determine correct speed and pressure for the material. Avoid excessive heat buildup by using light pressure and intermittent passes to prevent damage to heat-sensitive plastics or surface coatings.
