Description
Conform to the surface, not the other way around. The Proxxon flap wheel is a conformable abrasive tool that flexes to match flat, curved, and contoured surfaces — including the inside of round workpieces where rigid abrasives can't follow the profile. At 120 grit, it's optimally positioned as a finishing sander: use it after heavier stock removal to refine the surface and prepare for polishing.
Key Specifications
- Diameter: 1-3/16" (approx. 30mm)
- Grit: 120
- Shank: 7/64" (3mm) — standard Micromot collet size
- Best use: Finishing sander after heavier surface sanding and material removal
- Part No.: 28985
Best Uses
- Finishing flat and contoured metal, wood, and plastic surfaces
- Sanding inside bores, tubes, and round workpieces
- Blending and smoothing curved profiles and fillets
- Pre-polish surface preparation after coarser abrasive work
Which Size Do You Need?
- Ø 1-3/16" (No. 28985): Larger diameter — better for open surfaces, larger bores, and faster coverage
- Ø 3/4" (No. 28984): Smaller diameter — better for tight bores, narrow slots, and confined spaces
Many users keep both sizes on hand for complete coverage across different workpiece geometries.
Frequently Asked Questions
What rotary tools are these compatible with?
These flap wheels fit any Micromot-compatible tool with a 3mm collet, including the IBS/E and IBS/A.
Can I use this on metal?
Yes — the flap wheel works on metal, wood, and plastic. For metal, it's best used as a finishing step after coarser grinding or filing to refine the surface before polishing.
What comes after 120 grit in the finishing sequence?
After the 120 grit flap wheel, move to the felt polishing bits with a polishing compound for a final high-gloss finish on metal.
