At 320 grit, this stone falls in the extra fine range, making it suited for final-stage polishing, edge cleanup, and light material removal where surface quality matters. The stone measures 6 inches in overall length and weighs 1 pound. It is not oil-filled, so no pre-conditioning is required before use. Machinists, tool and die workers, and general metalworking professionals reach for this type of stone when a consistent, controlled finish is the goal.\u003c\/p\u003e\n\u003cp\u003eThis polishing stone is used in metal fabrication shops, machine shops, and maintenance environments where hand stoning of flat or slightly contoured surfaces is part of standard workflow. Typical applications include removing burrs from machined edges, polishing mold surfaces, refining bearing fits, and preparing surfaces before final inspection. Its rectangular profile allows flat, uniform contact across a workpiece face, making it reliable for work on dies, fixtures, and precision components. No power tools are required — the stone is used by hand or with a honing guide.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320 grit extra fine aluminum oxide abrasive for final-stage polishing and light deburring\u003c\/li\u003e\n  \u003cli\u003eRectangular profile provides consistent flat contact on machined surfaces\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length gives adequate working surface for bench or hand use\u003c\/li\u003e\n  \u003cli\u003eNot oil-filled — ready to use dry or with a honing fluid of the technician's choice\u003c\/li\u003e\n  \u003cli\u003eLightweight at 1 pound for comfortable extended hand use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose hand polishing stone suitable for use on ferrous and non-ferrous metals, tooling steel, mold surfaces, and similar hard materials requiring fine abrasive finishing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis stone is a hand tool and requires no installation. Secure the workpiece in a vise or fixture before stoning to prevent movement during use. Apply a light honing oil or mineral oil to the stone surface if desired to reduce loading and extend stone life, keeping in mind the stone is not pre-filled. Inspect the stone face periodically for glazing and dress with a coarser abrasive or stone dresser if material removal slows noticeably.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eOil Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111908\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRU-MAXX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51032043M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51754448814386,"sku":"51032043M","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c8daf9e18e6a3be1eba8989b46c0d1d.jpg?v=1788945475","url":"https:\/\/voomisupply.com\/products\/tru-maxx-51032043m-rectangle-polishing-stone-320-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
