Constructed from medium-density wool felt, this bob delivers consistent polishing pressure and holds compound well for smooth, repeatable results. The 0.125-inch shank fits standard rotary tool collets and flex-shaft handpieces. With a maximum diameter of 0.25 inches and a head length of 0.25 inches, this bob is suited for detail work in tight contours, cavities, and precision bores. Machinists, toolmakers, jewelers, and finishing technicians are the primary users of this type of mounted point.\u003c\/p\u003e\u003cp\u003eThis mounted polishing bob is used in bench-top and portable rotary tool applications where small contact area and controlled polishing action are required. Typical applications include finishing inside bores, polishing mold cavities, blending tool marks on machined parts, and surface preparation on jewelry or small metal components. The cylinder profile maintains consistent edge contact along the length of the head, making it effective for flat-bottomed recesses and straight-walled cavities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCylinder shape provides consistent side and face contact for flat-bottomed and straight-walled surfaces\u003c\/li\u003e\n\u003cli\u003eMedium-density wool felt construction holds polishing compound and delivers controlled material removal\u003c\/li\u003e\n\u003cli\u003e0.125-inch shank diameter fits standard rotary tool and flex-shaft collets\u003c\/li\u003e\n\u003cli\u003eCompact 0.25-inch maximum diameter suited for fine detail and tight-access finishing\u003c\/li\u003e\n\u003cli\u003e0.25-inch head length with 2-inch shank for extended reach in recessed areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with rotary tools and flex-shaft handpieces accepting a 0.125-inch shank diameter collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank firmly in the collet before operating to prevent wobble or ejection at speed. Inspect the felt bob for wear, fraying, or uneven density before each use. Apply polishing compound directly to the bob rather than the workpiece for best results. Operate at manufacturer-recommended RPM for the tool being used and allow the bob to do the work without excessive pressure.\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\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: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00517 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131500\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: 516105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695558558002,"sku":"516105","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcbeab250930be33954219b820e95492.jpg?v=1788336446","url":"https:\/\/voomisupply.com\/products\/value-collection-516105-mounted-polishing-bob-cylinder","provider":"Voomi Supply","version":"1.0","type":"link"}
