Measuring 6 inches in overall length, 0.5 inches wide, and 0.25 inches thick, this stone delivers controlled material removal at a 400-grit super fine grade. It is not oil-filled, making it ready for dry use or with a compatible honing fluid. Machinists, toolmakers, and trade professionals reach for this stone when dressing edges, smoothing mating surfaces, or removing light burrs left from machining or fabrication operations.\u003c\/p\u003e\n\u003cp\u003eThis polishing stone is suited for bench work and hand-lapping applications in machine shops, maintenance environments, and light fabrication settings. Its slim profile — 0.5 inches wide and 0.25 inches thick — allows access to narrow slots, keyways, and tight-tolerance surfaces where larger stones cannot reach. The 6-inch length provides a comfortable grip for controlled strokes. It is a common choice for final finishing passes where surface quality matters more than stock removal rate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400-grit super fine aluminum oxide abrasive for smooth, controlled finishing\u003c\/li\u003e\n  \u003cli\u003eRectangular profile fits narrow slots, keyways, and recessed surfaces\u003c\/li\u003e\n  \u003cli\u003eNot oil-filled — compatible with dry use or honing oil application\u003c\/li\u003e\n  \u003cli\u003eCompact 6 inches x 0.5 inches x 0.25 inches form factor for precise hand control\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.12 pounds for extended bench work without fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose hand polishing stone for bench finishing, deburring, and surface conditioning tasks on metal, ceramic, and hard plastic workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis stone is a hand-held finishing tool requiring no power tools or special mounting. Secure the workpiece firmly in a vise or on a stable bench surface before use. Apply light, consistent pressure with even strokes; uneven pressure can round edges or create surface irregularities. If used with honing oil, apply sparingly and wipe the stone clean after each session to prevent loading.\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: 400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Super 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: 0.25 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\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4256404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693960134962,"sku":"4256404","price":76.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c72db7ca9ba374a6eb1c7b0ae42e60bc.jpg?v=1788319297","url":"https:\/\/voomisupply.com\/products\/value-collection-4256404-aluminum-oxide-polishing-stone-400g","provider":"Voomi Supply","version":"1.0","type":"link"}
