Built around a 5-inch diameter with a 5\/8-11 threaded arbor hole, this disc mounts directly to standard right-angle grinders without additional hardware. The 36-grit, very coarse ceramic alumina abrasive delivers high stock removal rates on hard metals, while the polyester-backed construction resists heat and flex fatigue under sustained grinding loads. Rated at 12,000 RPM maximum, it suits production grinding, weld blending, and surface preparation tasks in fabrication and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for use in metal fabrication shops, structural steel work, and field maintenance settings where rapid stock removal on carbon steel or stainless steel is required. The trimmable design allows the operator to dress the disc during use to expose fresh abrasive and extend service life. It is commonly installed by welders, ironworkers, pipefitters, and maintenance technicians using standard angle grinders with a 5\/8-11 spindle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e36-grit very coarse ceramic alumina abrasive for high stock removal\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile for surface grinding and weld blending\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor hole for direct spindle mounting on standard grinders\u003c\/li\u003e\n\u003cli\u003e12,000 RPM maximum speed rating\u003c\/li\u003e\n\u003cli\u003eTrimmable construction to expose fresh abrasive and extend disc life\u003c\/li\u003e\n\u003cli\u003eSuitable for carbon steel and stainless steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit standard right-angle grinders equipped with a 5\/8-11 threaded spindle.

Verify the grinder's rated no-load RPM does not exceed the 12,000 RPM disc rating before mounting. Guard the grinder properly and wear appropriate PPE including a face shield before operating. Inspect the disc for damage before each use and discard any disc showing cracks, gouges, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Thread Size\u003c\/strong\u003e: 5\/8-11\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: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina (Zirconia 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: Threaded Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester (Plastic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrimmable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R828\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 13 inches x 6 inches x 5.4 inches\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: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66623399127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544232001842,"sku":"66623399127","price":112.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25ccee7fae832a4e745dd54e23c349cf.jpg?v=1785926035","url":"https:\/\/voomisupply.com\/products\/norton-66623399127-flap-disc-36-grit-type-27-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
