Wool felt bobs are made from high-density compressed wool felt with a uniform shape and tight, even texture. Designed for use with rotary tools, they are ideal for fine polishing, deburring, mirror finishing, and the removal of light scratches on metals, stone, glass, ceramics, and painted surfaces. Their compact design makes them suitable for tight areas such as inner holes, grooves, and mold cavities.
