Developed to reduce by half the pressure needed while polishing, Cosima buffs are made with silicon-coated cotton fabric designed to produce nearly no dust during the polishing process. Suitable for polishing metals at low speeds (1,400 rpm), these 20-layer miniature buffs are available in diameters of 20, 22, and 24 mm. The buffs are sold individually or are available in packs of 12. Supplied by: Stuller Inc.
