Description
Gentle surface finishing for metals including precious metals. The Proxxon nylon fleece brushes provide two grades — coarse and fine — for cleaning, polishing, light sanding, matt finishing, and deburring of steel, stainless steel, gold, silver, and titanium. The nylon fleece construction is aggressive enough to remove oxidation and light surface deposits but gentle enough for use on precious metals where wire brushes or abrasive wheels would scratch or remove material. Both brushes use the standard 2.35mm (3/32") Micromot shank.

Frequently Asked Questions
Why nylon fleece instead of wire brushes for precious metals?
Wire brushes can scratch soft metals like gold and silver and may leave steel wire contamination on stainless steel and titanium. Nylon fleece provides effective cleaning and finishing action without the risk of scratching or contamination.
What shank size do these use?
3/32" (2.35mm) — compatible with the 2.35mm collet in the Proxxon MICROMOT Steel Collet Set (No. 28940).
