Measuring 6 inches in overall length, 0.5 inches wide, and 0.125 inches thick, this stone carries a 320 grit rating, placing it in the extra fine category. It is not oil-filled, making it ready for dry use or use with a honing fluid of the technician's choice. Machinists, tool-and-die makers, and maintenance technicians reach for stones like this when flat, controlled stock removal on tight tolerances is required.\u003c\/p\u003e\u003cp\u003eThis polishing stone is suited for bench work and hand-lapping applications across manufacturing, maintenance, and repair environments. Its slim profile — 0.125 inches thick — allows access to narrow slots, keyways, and confined surfaces where larger stones cannot reach. The extra fine 320 grit delivers a smooth surface finish with minimal material removal, making it appropriate for finishing passes rather than aggressive stock removal. It is commonly used in industrial shops, toolrooms, and field maintenance settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit extra fine aluminum oxide construction for smooth, controlled finishing\u003c\/li\u003e\n\u003cli\u003eSlim 0.125-inch thickness provides access to narrow slots, keyways, and tight geometry\u003c\/li\u003e\n\u003cli\u003e6-inch overall length gives adequate working surface for hand-lapping and bench use\u003c\/li\u003e\n\u003cli\u003eNot oil-filled — compatible with dry use or technician-supplied honing fluid\u003c\/li\u003e\n\u003cli\u003eRectangular profile maintains flat, consistent contact on machined surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or supplemental polishing stone for hand-lapping, deburring, and surface finishing applications on metal, tooling, and machined components where 320 grit extra fine abrasive is appropriate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis stone is a hand-applied abrasive tool and does not require power-down procedures for installation. Secure the workpiece before use to prevent movement during finishing passes. Apply consistent, even pressure along the full length of the stone to maintain a flat cutting action and avoid rocking. When using with a honing oil or fluid, apply sparingly and clean the stone face periodically to prevent loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111908\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: 4256303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699657474354,"sku":"4256303","price":70.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/690696c1d4f572dfe33940b75b264063.jpg?v=1788378791","url":"https:\/\/voomisupply.com\/products\/value-collection-4256303-aluminum-oxide-polishing-stone-320-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
