At 400 grit, it falls in the super fine category, making it well suited for removing light burrs, smoothing machined edges, and achieving consistent surface finish without aggressive stock removal. The stone measures 4 inches in overall length with a 1\/8 inch by 1\/8 inch square cross section, giving it a slim profile that fits into slots, grooves, and tight cavities that wider stones cannot reach. It is not oil filled. Machinists, toolmakers, and maintenance technicians are the typical users.\u003c\/p\u003e\u003cp\u003eThis polishing stone is used in precision hand-finishing applications across manufacturing, toolroom, and maintenance environments. The square profile and narrow cross section make it practical for honing keyways, die cavities, and narrow channels. At 400 grit super fine, it is best applied as a final finishing step after coarser abrasive work has already been completed. It is sold in packages of 12, making it a practical shop consumable for benches that go through finishing stones regularly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 grit super fine aluminum oxide abrasive for light finishing and deburring\u003c\/li\u003e\n\u003cli\u003eSquare 1\/8 inch by 1\/8 inch cross section accesses narrow slots, grooves, and cavities\u003c\/li\u003e\n\u003cli\u003e4 inch overall length provides good hand control during finishing passes\u003c\/li\u003e\n\u003cli\u003eNot oil filled — compatible with dry use or user-applied honing fluid\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 12 for consistent shop replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand polishing stone suitable for use on metal, ceramic, and composite workpieces where a super fine 400 grit aluminum oxide abrasive and a square profile are appropriate for the finishing task.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHand polishing stones of this type require no power tools and are applied by hand or in a manual holder with controlled strokes. Secure the workpiece before use to prevent movement during finishing passes. Honing oil or a light cutting fluid may be applied to extend stone life and improve swarf clearance, though dry use is also acceptable. Inspect the stone for chips or uneven wear before each use and replace if the profile is no longer consistent.\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: 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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1\/8 inch\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: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 8906269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714165899570,"sku":"8906269","price":36.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a145c1c489afebb3e33212b73225cd2e.jpg?v=1788497085","url":"https:\/\/voomisupply.com\/products\/value-collection-8906269-square-polishing-stone-400-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
