Built with a cloth backing and coated abrasive construction, it delivers consistent stock removal and a controlled surface finish in a single operation. At 80 grit, this medium-grade disc cuts efficiently without excessive heat buildup, making it a reliable choice for weld blending, deburring, and surface preparation. The disc is rated for a maximum speed of 12,000 RPM and accepts a standard 7\/8 inch arbor hole, fitting most angle grinders used in fabrication and industrial maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for metal fabrication shops, welding operations, structural steel work, and general industrial maintenance. The Type 27 flat profile keeps the abrasive surface parallel to the workpiece, which is preferred for flat-surface grinding and stock removal rather than edge work. The zirconia alumina abrasive is a strong performer on mild steel, stainless steel, and other ferrous metals under moderate to heavy material removal conditions. The disc is trimmable, allowing technicians to expose fresh abrasive and extend usable disc life during extended jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 flat profile for flat-surface grinding and weld blending\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive for aggressive stock removal on ferrous metals\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade balances cut rate with surface finish\u003c\/li\u003e\n  \u003cli\u003eCloth backing provides durability and flexibility under load\u003c\/li\u003e\n  \u003cli\u003eTrimmable construction extends disc life by exposing fresh abrasive\u003c\/li\u003e\n  \u003cli\u003e12,000 RPM maximum speed rating suits standard angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style flap disc for angle grinders accepting a 7\/8 inch arbor hole and operating at up to 12,000 RPM.

Before mounting, verify that the angle grinder is rated at or above the disc maximum speed of 12,000 RPM and that the arbor size matches the 7\/8 inch center hole. Always disconnect power from the grinder before mounting or removing the disc, and confirm the disc is properly seated and the guard is in place before operation. Do not exceed the rated RPM and inspect the disc for damage before each use.\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: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\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\u003ePackage Dimensions\u003c\/strong\u003e: 7.4 inches L x 6.9 inches W x 7.2 inches H\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: 66623399151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541745795378,"sku":"66623399151","price":122.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bac1e135716d39d0caf1be9967ffa1d.jpg?v=1785883799","url":"https:\/\/voomisupply.com\/products\/norton-66623399151-flap-disc-80-grit-type-27-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
