Measuring 0.5 inches wide by 0.5 inches thick with a 6-inch overall length, this stone delivers consistent material removal at 320 grit, classified as extra fine. It is not oil-filled, making it ready for use dry or with a compatible honing fluid. Machinists, tool-and-die technicians, mold makers, and maintenance mechanics rely on this stone type for edge work, cavity polishing, and precision surface preparation where controlled stock removal is required.\u003c\/p\u003e\u003cp\u003eThis polishing stone is suited for bench work and hand-applied finishing operations in machine shops, toolrooms, and industrial maintenance environments. Its square cross-section allows access to flat surfaces, slots, and right-angle features that round or wedge profiles cannot reach. The extra fine grit makes it appropriate for final-pass polishing after coarser abrasive work, producing a smooth, refined surface finish. It ships in a package quantity of six stones.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit extra fine aluminum oxide for controlled final-pass polishing\u003c\/li\u003e\n\u003cli\u003eSquare profile accesses flat surfaces, slots, and internal corners\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides comfortable hand grip and stroke length\u003c\/li\u003e\n\u003cli\u003e0.5 inch by 0.5 inch cross-section for consistent edge contact\u003c\/li\u003e\n\u003cli\u003eNot oil-filled — use dry or with honing oil as the application requires\u003c\/li\u003e\n\u003cli\u003eSold in a package of six stones\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand polishing stone for use on hardened steel, tool steel, cast iron, ceramic, and similar hard materials in bench finishing and toolroom applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis stone is a hand-applied abrasive tool and does not require mechanical installation. Secure the workpiece firmly before applying the stone to prevent movement during finishing strokes. Use a compatible honing oil or work dry depending on the material and desired finish result. Inspect the stone surface periodically for glazing or uneven wear and dress as needed to maintain cutting performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 4256305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703206314290,"sku":"4256305","price":71.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/897fd567d578cf068a46c593f513ea83.jpg?v=1788415381","url":"https:\/\/voomisupply.com\/products\/value-collection-4256305-square-polishing-stone-320-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
