Filzbobs-Set – 13 compressed wool felt polishing bobs for precise finishing What this set gives you 13 wool felt bobs made from compressed wool fibers, providing a firm, durable polishing surface. Irregular bob shapes let you reach and finish tight spots, grooves, and conical parts that round wheels miss. Designed to produce a mirror-like finish on a wide range of materials, improving the final quality of your work. Key benefits Better access: irregular forms make it easy to polish hard-to-reach areas and internal contours. Versatile compatibility: works with sanding machines and rotary tools and fits common tool attachments and collets. Time and quality: achieve fine, consistent polishing without changing tools frequently; ideal for delicate finishing and detail work. Important attributes Material: compressed wool felt for durable, fine polishing action. Quantity: 13 bobs in one set to cover different shapes and polishing needs. Function: polishing and finishing of metal and non-metal surfaces, including fine detail areas and complex profiles. Performance and results Capable of producing mirror-like surfaces on metals, glass, jewelry, molds, and precision parts. Effective on difficult shapes such as intricate grooves, tapered or conical components, and small internal recesses. Suitable for both coarse smoothing and final high-gloss refinement when used with appropriate compounds. Practical use scenarios 1) Jewelry finishing: polish rings, settings, and small components to a bright, even shine without damaging delicate details. 2) Mold and tool maintenance: restore smooth cavity surfaces and remove fine burrs inside molds and dies for improved part quality. 3) Precision parts and electronics: refine connectors, metal housings, and small machined parts where controlled, localized polishing is required. How to use Attach the appropriate bob to your rotary tool or sanding machine using the compatible collet/attachment. Apply the desired polishing compound or use dry for light finishes. Work at moderate speed with light pressure; let the felt do the polishing to avoid overheating or removing material. What makes this set stand out A complete selection of 13 felt bobs covering a range of detail work and surface profiles. Compressed wool construction balances durability with the softness needed for high-gloss finishing. Specifically suited for fine-detail polishing where shape and access matter. Filzbobs-Set is a practical toolkit addition for jewelers, mold makers, metalworkers, and hobbyists who need precise, professional polishing results across a variety of materials and shapes.
