The 5-inch disc features a 7\/8-inch arbor hole and runs at a maximum of 12,000 RPM on compatible angle grinders. Backed by a durable cloth substrate, the zirconia alumina abrasive grain self-sharpens under pressure, maintaining cut rate through the life of the disc. At 36 grit, this is a very coarse grade tool suited for rapid stock removal, weld blending, and surface prep before finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis flap disc fits standard 5-inch angle grinders and is used in metal fabrication shops, structural steel work, and general welding applications. The Type 27 flat-profile configuration keeps the disc face parallel to the workpiece, making it well suited for flat surface grinding and blending. The trimmable design allows the operator to expose fresh abrasive material as the flaps wear, extending usable disc life. Typical users include fabricators, ironworkers, pipefitters, and maintenance welders working on mild steel, stainless, and similar ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive grain for high cut rate and long disc life on metal\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile for flush surface grinding and weld blending\u003c\/li\u003e\n  \u003cli\u003e36 grit very coarse grade for rapid stock removal\u003c\/li\u003e\n  \u003cli\u003eCloth backing provides durability and flexibility under load\u003c\/li\u003e\n  \u003cli\u003eTrimmable construction allows fresh abrasive exposure as flaps wear\u003c\/li\u003e\n  \u003cli\u003e12,000 RPM maximum rated speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard 5-inch angle grinders with a 7\/8-inch arbor.

Always power down and unplug or lock out the grinder before mounting or changing the disc. Confirm the grinder guard is in place and that the disc is rated at or above the tool's maximum RPM before operation. Wear appropriate eye and face protection per ANSI and applicable shop safety requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 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: Zirconia 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: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\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\u003ePackage Dimensions\u003c\/strong\u003e: 7.1 x 7 x 6.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66623399148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539216204082,"sku":"66623399148","price":140.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29c533c8d0dae174a4df93c4df9a5e03.jpg?v=1785836687","url":"https:\/\/voomisupply.com\/products\/norton-66623399148-flap-disc-5-in-36-grit-zirconia-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
