It is used for fine surface finishing, deburring, and honing operations on metal, ceramic, and composite workpieces. At 400 grit, this stone falls in the super fine grade range, making it well suited for final-stage surface preparation where a smooth, refined finish is required. The stone measures 6 inches in overall length and weighs 1 pound. It is not oil-filled, so no pre-soaking or conditioning is needed before use. Machinists, toolmakers, and maintenance technicians typically use this type of stone in shop and field settings.\u003c\/p\u003e\u003cp\u003eThis polishing stone is appropriate for bench work and hand-lapping applications across manufacturing, maintenance, and fabrication environments. It performs well on tool edges, mold surfaces, valve seats, and precision mechanical components where surface finish tolerance matters. The super fine 400 grit designation makes it a finishing stone rather than a stock-removal tool. It is used after coarser grits have completed initial shaping and the goal shifts to refining surface texture and removing minor scratches or burrs left by previous operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive construction provides consistent cutting action on hard materials\u003c\/li\u003e\n\u003cli\u003e400 grit super fine grade suited for final-stage honing and polishing\u003c\/li\u003e\n\u003cli\u003eRectangle shape allows flat surface contact for consistent, uniform results\u003c\/li\u003e\n\u003cli\u003e6-inch overall length gives adequate working surface for hand and bench use\u003c\/li\u003e\n\u003cli\u003eNot oil-filled, allowing immediate use without pre-conditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand polishing and honing stone for use on metal, ceramic, and composite surfaces in machining and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power tools or special installation is required for this hand stone. Keep the working surface clean and free of debris during use to maintain consistent abrasive contact. A light honing oil or water lubricant may be applied during use to float away swarf and extend stone life, even though the stone itself is not pre-filled. Store the stone in a dry location to prevent contamination of the abrasive surface.\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: 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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 01556331M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51755307467058,"sku":"01556331M","price":29.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36b60dcfc4fda59794f1eadee2768b6b.jpg?v=1788953430","url":"https:\/\/voomisupply.com\/products\/tru-maxx-01556331m-silicon-carbide-polishing-stone-400-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
