It carries a 36-grit, very coarse grade rating and runs on a 4.5-inch diameter with a 7\/8-inch arbor hole. The polyester backing provides consistent flap support and flex during grinding passes. Maximum rated speed is 13,300 RPM, making it compatible with standard 4.5-inch angle grinders used across fabrication shops, structural steel work, and general metalworking trades. The green ceramic alumina abrasive delivers cooler cutting and extended life compared to conventional aluminum oxide discs on harder base metals.\u003c\/p\u003e\u003cp\u003eThis disc is suited for surface grinding, weld blending, and edge deburring on carbon steel, stainless steel, and similarly hard ferrous alloys. The Type 27 flat-center profile keeps the disc flush against flat workpieces and inside welds, giving metal fabricators and welders clean, controlled contact. The trimmable design allows the operator to expose fresh abrasive as the flaps wear, extending usable disc life before replacement is needed. This disc is a single-unit package with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e36-grit ceramic alumina abrasive for very coarse, high-rate material removal\u003c\/li\u003e\n\u003cli\u003eType 27 flat-center profile for flush surface and weld grinding\u003c\/li\u003e\n\u003cli\u003ePolyester backing provides stable flap support and consistent flex\u003c\/li\u003e\n\u003cli\u003eRated to 13,300 RPM for use with standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003cli\u003eTrimmable flap design extends disc service life\u003c\/li\u003e\n\u003cli\u003eGreen disc color for quick visual identification of ceramic alumina grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch angle grinders fitted with a 7\/8-inch arbor.

Always confirm the grinder's rated RPM does not exceed the disc's 13,300 RPM maximum before mounting. Power down and disconnect the grinder from its power source before mounting or removing any disc. Wear appropriate PPE including face shield, gloves, and hearing protection during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 7\/8 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: 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\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: Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 11.6 inches x 5.5 inches x 5 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: 66623399126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541569962290,"sku":"66623399126","price":95.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd86fc41ced32fd7a286af0610d9b432.jpg?v=1785879430","url":"https:\/\/voomisupply.com\/products\/norton-66623399126-ceramic-alumina-flap-disc-36-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
