Built with a coarse 40-grit abrasive bonded to a plastic backing, this disc delivers consistent cut rates across aluminum, stainless steel, and other non-ferrous metals. The zirconia alumina grain self-sharpens during use, extending disc life compared to standard aluminum oxide. Rated to 13,300 RPM, it fits standard 5\/8-11 arbor spindles and carries a trimmable design that allows the operator to expose fresh abrasive as the flap wears. Fabricators, welders, and metal finishing techs will find it suited to weld blending, edge chamfering, and surface prep work.\u003c\/p\u003e\u003cp\u003eThis flap disc is intended for use on 4.5-inch angle grinders in metal fabrication, structural steel, and sheet metal applications. Its material compatibility includes aluminum, non-ferrous metals, and stainless steel, making it a practical choice for shops that work across multiple substrate types without swapping discs. The Type 27 flat profile is well-suited to flat surface grinding and blending rather than edge work, and the plastic backing keeps weight low while resisting heat buildup during extended passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e40-grit coarse zirconia alumina abrasive for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile optimized for flat surface grinding and blending\u003c\/li\u003e\n\u003cli\u003ePlastic backing reduces weight and resists heat during use\u003c\/li\u003e\n\u003cli\u003eTrimmable design exposes fresh abrasive as the disc wears\u003c\/li\u003e\n\u003cli\u003eRated to 13,300 RPM for use on standard angle grinders\u003c\/li\u003e\n\u003cli\u003eCompatible with aluminum, stainless steel, and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders equipped with a 5\/8-11 arbor spindle.

Always confirm the grinder's rated RPM meets or exceeds the disc's 13,300 RPM maximum before mounting. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or abrasive separation. Use appropriate PPE including eye protection and gloves when operating grinding equipment.\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: 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: 40 (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: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Angle Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Non-Ferrous Metal, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrimmable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 06-F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.032 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER SURFACE TECHNOLOGIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 06F454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67914976887090,"sku":"06F454","price":30.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f722493eaa10c7a408a7ad8242d0531.jpg?v=1791251756","url":"https:\/\/voomisupply.com\/products\/walter-surface-technologies-06f454-flap-disc-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
