Description
Wide, flat, and consistent. The Proxxon disc-shape felt polishing bits are built for broad surface finishing — flat faces, large flat recesses, and open surfaces where you need maximum felt contact in a single pass. The disc profile covers more area per stroke than bullet or cylindrical shapes, making it the fastest option for flat-surface polishing on metal, non-ferrous metal, and plastic.

Choosing the Right Felt Bit Shape
All three Proxxon felt bit shapes share the same 3/32" shank and $7 price point — the difference is geometry:
- Disc (No. 28803): Best for flat, open surfaces — maximum contact area per pass
- Cylindrical (No. 28802): Best for slots, straight bores, and flat-bottomed recesses
- Bullet (No. 28801): Best for curved surfaces, contours, and tapered recesses
Many users keep all three on hand for complete finishing coverage. The 10-piece Polishing Accessory Set includes multiple shapes and sizes in one kit.
Frequently Asked Questions
What rotary tools are these compatible with?
These bits fit any Micromot-compatible tool with a 3/32" (2.35mm) collet, including the IBS/E and IBS/A.
Can I use these with polishing compound?
Yes — the disc shape is particularly effective for applying and working in compound over flat surfaces. Apply a small amount of paste to the felt face before use.
