Part of the Q421 series, it features a closed-coat construction on a cloth backing, delivering consistent abrasive coverage across the full sheet surface. Silicon carbide cuts faster than aluminum oxide on hard, dense materials, making it a reliable choice for finish work on metals, ceramics, stone, and composites. This sheet is suited for trade and shop environments where surface prep quality directly affects the final result.\u003c\/p\u003e\n\u003cp\u003eThis sanding sheet is used in residential and commercial maintenance, fabrication, and finishing operations. Its wet-dry capability makes it practical for applications requiring lubrication to control heat and reduce surface loading. Dry use is equally supported. The cloth backing provides flexibility and durability under hand sanding or block sanding pressure. Typical install scenarios include surface prep before coating, rust removal, paint feathering, and final-pass finishing on hard substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320 extra-fine grit silicon carbide abrasive for smooth, controlled material removal\u003c\/li\u003e\n  \u003cli\u003eClosed-coat construction maximizes abrasive density across the sheet surface\u003c\/li\u003e\n  \u003cli\u003eCloth backing adds flexibility and tear resistance compared to paper alternatives\u003c\/li\u003e\n  \u003cli\u003eRated for both wet and dry sanding use\u003c\/li\u003e\n  \u003cli\u003ePart of the Q421 series for consistent abrasive performance across sheet batches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose abrasive sheet compatible with hand sanding blocks and flat-pad sanding applications where a standard sheet format is required.

When sanding wet, ensure the workpiece and surrounding area are safe for water contact and that any electrical equipment is isolated. Inspect the sheet before use and discard if torn or loaded with debris. Always sand with appropriate respiratory protection when working with fine abrasive dust.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\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\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoat Density\u003c\/strong\u003e: Closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet or Dry\u003c\/strong\u003e: Wet and Dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Q421\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Resistant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261100920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51701062336818,"sku":"66261100920","price":16040.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f435e9a46fae5399900a5cecf3a9e4a8.jpg?v=1788397667","url":"https:\/\/voomisupply.com\/products\/norton-66261100920-320-grit-silicon-carbide-sanding-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
