At 4 inches in overall length with a 1-inch by 1-inch cross section, this stone delivers consistent contact across flat and broad work surfaces. The 220 grit, very fine grade makes it suitable for final-stage finishing passes where surface smoothness and dimensional accuracy matter. It is not oil-filled, so it is used dry or with a light honing oil applied by the technician. Machinists, tool-and-die workers, and maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis polishing stone fits standard hand-lapping and finishing applications on ferrous and non-ferrous metals, mold surfaces, tooling, and machined components. The square profile allows uniform pressure distribution across a flat work surface and provides four working edges for edge-breaking and fine burr removal. It is well suited for bench work and in-place surface conditioning where a power tool would be impractical or too aggressive.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e220 grit, very fine grade aluminum oxide abrasive for final-stage surface finishing\u003c\/li\u003e\n  \u003cli\u003eSquare cross section — 1 inch by 1 inch — for full-face contact on flat surfaces\u003c\/li\u003e\n  \u003cli\u003e4 inches overall length for comfortable hand grip and extended reach\u003c\/li\u003e\n  \u003cli\u003eNot oil-filled — use dry or apply honing oil as needed for the application\u003c\/li\u003e\n  \u003cli\u003eFour working edges suitable for deburring, edge-breaking, and corner finishing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard bench stone for hand-lapping and finishing applications on machined metal surfaces across general manufacturing and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePolishing stones are applied by hand by machinists or maintenance technicians — no power tools required. Secure the workpiece before applying the stone to prevent movement during finishing passes. When using with honing oil, apply a small amount to the stone surface to reduce loading and improve cutting action. Inspect the stone periodically for glazing; a loaded or glazed surface reduces cutting efficiency and should be dressed or replaced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\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\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: 51032258M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51747535716658,"sku":"51032258M","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97c746d78f30f748bff0424b27c8ff1d.jpg?v=1788882092","url":"https:\/\/voomisupply.com\/products\/tru-maxx-51032258m-square-polishing-stone-220-grit-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
