Designed for coarse stock removal, this 2-inch disc uses a coated abrasive construction backed by fiberglass for rigidity and heat resistance during aggressive grinding. At 40 grit, it is built for fast material removal on metal, weld seams, and surface preparation work. The ceramic alumina abrasive grain self-sharpens under pressure, extending usable disc life compared to standard aluminum oxide. Rated to 30,000 RPM, it suits high-speed angle grinders and die grinders used in fabrication, maintenance, and general metalworking applications. Licensed trades and shop professionals are the primary installers of this consumable.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for use on ferrous and non-ferrous metals in both shop and field environments. The Type 27 flat-profile design allows flush grinding on flat and slightly curved surfaces. The Quick-Change Type R attachment eliminates the need for a separate backing pad or wrench, making disc swaps faster during production runs or repair work. Typical applications include weld blending, rust removal, deburring, and surface conditioning on structural steel, pipe, sheet metal, and fabricated components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40 grit ceramic alumina abrasive for aggressive, coarse-grade stock removal\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile allows flush grinding on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eQuick-Change Type R attachment for tool-free disc changes on compatible grinders\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing provides structural support and heat resistance during use\u003c\/li\u003e\n  \u003cli\u003e30,000 RPM maximum speed rating suits high-speed pneumatic and electric grinders\u003c\/li\u003e\n  \u003cli\u003eCoated abrasive construction with self-sharpening ceramic alumina grain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders and die grinders equipped with a Quick-Change Type R compatible hub or mandrel.

Confirm the tool is powered off and disconnected from its air or electrical source before changing discs. Always verify the grinder RPM rating matches or falls below the disc maximum before operation. Inspect the disc for damage before each use and follow applicable ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Quick-Change Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.63 inches L x 3.38 inches W x 2.25 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 pounds\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: 77696090146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539464913202,"sku":"77696090146","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b55a34518b9c1eff961cbe24206da2a7.jpg?v=1785840781","url":"https:\/\/voomisupply.com\/products\/norton-77696090146-flap-disc-40-grit-type-27-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
