Measuring 6 inches in overall length, 0.5 inches wide, and 0.25 inches thick, this stone delivers controlled material removal in tight or narrow areas where larger abrasives cannot reach. The 320 grit extra fine rating makes it well suited for final-stage honing, light stock removal, and achieving smooth surface finishes. Machinists, tool-and-die technicians, and maintenance trades keep this type of stone on hand for precision hand-finishing tasks.\u003c\/p\u003e\u003cp\u003eThis polishing stone is used in bench and hand-finishing applications across metalworking, maintenance, and toolroom environments. The slim rectangular profile fits grooves, keyways, mold cavities, and flat surfaces. The green silicon carbide composition cuts cleanly on hardened steels, cast iron, carbide tooling, and non-ferrous materials. It is not oil-filled, so a light application of honing oil or water-based coolant is typically used during service to flush swarf and extend stone life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit extra fine grade for final-stage finishing and light deburring\u003c\/li\u003e\n\u003cli\u003eSilicon carbide abrasive cuts effectively on hardened steel, carbide, cast iron, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eSlim rectangular profile fits keyways, slots, grooves, and flat work surfaces\u003c\/li\u003e\n\u003cli\u003eNot oil-filled, compatible with honing oil or water-based coolant\u003c\/li\u003e\n\u003cli\u003eGreen color for easy grade identification in a toolroom setting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand polishing stone for bench finishing, deburring, and honing applications in metalworking and maintenance trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power tools or mechanical installation are required. Apply a light coat of honing oil or appropriate coolant to the stone face before use to prevent loading and extend abrasive life. Keep the stone flat and use consistent hand pressure to avoid rounding edges or grooving the stone surface. Inspect the stone for chips or cracks before each use and replace if structural integrity is compromised.\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: Silicon Carbide\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\u003eColor\u003c\/strong\u003e: Green\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: 0.25 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\u003ePackage Quantity\u003c\/strong\u003e: 12\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: 4121304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698526781746,"sku":"4121304","price":97.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ed785c031ebd01b28c467755886a480.jpg?v=1788364236","url":"https:\/\/voomisupply.com\/products\/value-collection-4121304-rectangle-polishing-stone-320-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
