Constructed from hard-density wool felt, this oval-shaped bob delivers consistent contact pressure and controlled material removal when chucked into a rotary tool, die grinder, or drill press. The 1\/4-inch shank seats securely in standard collets and chucks, while the 1-inch maximum diameter and 1-inch head length provide reach into contoured surfaces and tight geometries. At under 0.04 pounds, the bob adds negligible rotating mass, supporting stable high-speed operation.\u003c\/p\u003e\n\u003cp\u003eThis mounted polishing bob is suited for toolroom, maintenance, and production finishing applications where a consistent, repeatable polish is required on small or detailed workpieces. Typical use cases include polishing mold cavities, deburring machined bores, and surface-finishing jewelry, instrument components, or precision hardware. The hard-density wool felt construction is appropriate for applying polishing compounds to achieve a refined surface finish without aggressive material removal. Machinists, toolmakers, and metalworking professionals are the primary installers and users of this accessory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOval bob shape conforms to contoured and recessed surfaces for even polish contact\u003c\/li\u003e\n  \u003cli\u003eHard-density wool felt construction provides firm, controlled polishing action\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits standard die grinder collets and drill chuck sizes\u003c\/li\u003e\n  \u003cli\u003e1-inch maximum diameter and 1-inch head length suit small-bore and cavity work\u003c\/li\u003e\n  \u003cli\u003e2-inch shank length provides clearance when working in deeper recesses\u003c\/li\u003e\n  \u003cli\u003eLightweight at approximately 0.04 pounds, minimizing rotational imbalance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any rotary tool, die grinder, or drill accepting a standard 1\/4-inch shank mounted accessory.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed or experienced machinist or toolroom technician should mount the bob in a properly rated collet or chuck rated for the intended RPM. Ensure the rotary tool is powered off and fully stopped before inserting or removing the shank. Inspect the wool felt head for wear, fraying, or imbalance before each use, and do not exceed the tool manufacturer's maximum recommended RPM for mounted accessories of this diameter. Apply polishing compound sparingly to the felt surface rather than to the workpiece to maintain even distribution.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBob Shape\u003c\/strong\u003e: Oval\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBob Material\u003c\/strong\u003e: Wool Felt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBob Density\u003c\/strong\u003e: Hard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (H x W x L)\u003c\/strong\u003e: 3 x 1 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Value Collection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 516142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717358485810,"sku":"516142","price":21.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/775fd5b0ff9beabb2194c42504f3a2b1.jpg?v=1788539079","url":"https:\/\/voomisupply.com\/products\/value-collection-516142-oval-wool-felt-polishing-bob-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
