Description
Tight spaces, smooth results. The Proxxon 3/4" flap wheel is the smaller-diameter option in the Proxxon flap wheel range — a conformable abrasive that flexes to match flat, curved, and contoured surfaces, including the inside of narrow bores and confined workpiece geometries where the larger 1-3/16" wheel won't fit. At 120 grit, it's optimally positioned as a finishing sander after heavier stock removal.
Key Specifications
- Diameter: 3/4" (approx. 19mm)
- Grit: 120
- Shank: 7/64" (3mm) — standard Micromot collet size
- Best use: Finishing sander after heavier surface sanding and material removal
- Part No.: 28984
Best Uses
- Sanding inside narrow bores, tubes, and tight round workpieces
- Finishing contoured surfaces and fillets in confined areas
- Blending and smoothing in spaces the larger flap wheel can't reach
- Pre-polish surface preparation after coarser abrasive work
Which Size Do You Need?
- Ø 3/4" (No. 28984): Smaller diameter — better for tight bores, narrow slots, and confined spaces
- Ø 1-3/16" (No. 28985): Larger diameter — better for open surfaces, larger bores, and faster coverage
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, use it as a finishing step after coarser grinding to refine the surface before polishing.
What comes after 120 grit in the finishing sequence?
After the flap wheel, move to the felt polishing bits with a polishing compound for a final high-gloss finish on metal — the bullet shape works particularly well on contoured surfaces.
