Constructed from hard-density wool felt, this bob delivers consistent polishing pressure and holds compound well during rotary tool operations. The 1\/8 inch shank fits standard rotary tool chucks and flex-shaft handpieces. With a maximum diameter of 0.5 inches and a head length of 1 inch, it is sized for detail work in confined areas, recesses, and small contoured surfaces. Machinists, tool and die makers, jewelers, and metal fabricators commonly use this type of accessory for final-pass polishing and light deburring tasks.\u003c\/p\u003e\u003cp\u003eThis mounted polishing bob is suited for use with bench grinders equipped with handpiece attachments, flex-shaft machines, and standard rotary tools accepting 1\/8 inch shanks. It is appropriate for both shop and field finishing applications where a small, controllable polishing head is needed. The hard felt density makes it well matched to work where firm contact and moderate compound retention are required, such as polishing bores, slots, and curved internal surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCylinder shape provides even surface contact across the full head diameter during polishing passes\u003c\/li\u003e\n\u003cli\u003eHard-density wool felt construction holds polishing compound and delivers controlled cutting action\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter fits standard rotary tool chucks and flex-shaft handpieces without adapters\u003c\/li\u003e\n\u003cli\u003e1 inch head length reaches into recesses and blind features that larger bobs cannot access\u003c\/li\u003e\n\u003cli\u003e2 inch shank length provides clearance when working inside deep cavities or through fixtures\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds, reducing hand fatigue during extended detail work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard mounted polishing bob for use with rotary tools, flex-shaft machines, and similar power handpieces that accept a 1\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by inserting the 1\/8 inch shank into the collet or chuck of the rotary tool and tightening securely before operation. Ensure the tool is powered off and unplugged before mounting or removing the bob. Inspect the felt head for wear or separation before each use and replace if the material is uneven or detached from the shank. Apply polishing compound to the bob rather than directly to the workpiece for best results.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBob Shape\u003c\/strong\u003e: Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.5 inches\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: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2 inches\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 516121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694318027058,"sku":"516121","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4683a1adeb83f0b01246b20b38ece36.jpg?v=1788323047","url":"https:\/\/voomisupply.com\/products\/value-collection-516121-mounted-polishing-bob-cylinder-wool-felt","provider":"Voomi Supply","version":"1.0","type":"link"}
