Built in an oval shape from rock-hard density wool felt, this bob delivers firm, consistent contact pressure suited to deburring, finish polishing, and detail work in recesses or contoured surfaces. The 1\/4-inch shank diameter mounts directly into standard die grinders, rotary tools, and drill press chucks. Maximum bob diameter is 1 inch with a head length of 1 inch and a 2-inch shank length, making it compact and easy to control in tight workspaces.\u003c\/p\u003e\u003cp\u003eThis polishing bob is used across metalworking, toolmaking, jewelry finishing, and precision machining applications. Its rock-hard felt density makes it appropriate for use with polishing compounds on hardened metals and ferrous surfaces where a softer felt would deflect or wear too quickly. Machinists, toolmakers, and fabricators typically reach for this style of bob when working bore interiors, shaft ends, or small contoured faces that require a mounted abrasive or polishing media on a rotating tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOval bob shape for consistent contact on curved and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eRock-hard wool felt density for firm polishing pressure with compound\u003c\/li\u003e\n\u003cli\u003e1-inch maximum diameter fits standard die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter for wide tool compatibility\u003c\/li\u003e\n\u003cli\u003e2-inch shank length provides clearance for deep-reach applications\u003c\/li\u003e\n\u003cli\u003eCompact 1-inch head length for use in tight or recessed areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with die grinders, rotary tools, and drill presses accepting a 1\/4-inch shank mounted accessory.

Before mounting, ensure the rotary tool or die grinder is powered off and unplugged or air supply is isolated. Insert the 1\/4-inch shank fully into the collet and tighten securely before operation. Do not exceed the maximum RPM rating of the tool or apply side loads that could deflect the shank.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Rock 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\u003eWeight\u003c\/strong\u003e: 0.04 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: 516143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701671919922,"sku":"516143","price":21.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4376ea8631d1db30a158389b4e47e8d1.jpg?v=1788403486","url":"https:\/\/voomisupply.com\/products\/value-collection-516143-mounted-polishing-bob-oval-wool-felt","provider":"Voomi Supply","version":"1.0","type":"link"}
