The Proxxon cylindrical felt polishing bits deliver consistent, even contact across flat recesses, slots, and straight-walled bores — ideal for fine finishing and polishing on metal, non-ferrous metal, and plastic.

Bullet vs. Cylindrical — Which Shape Do You Need?

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.
Should I use polishing compound with these?
Yes — for metal finishing, a polishing paste or compound applied to the felt significantly improves results. The cylindrical shape holds compound evenly along its full length.
