Built on a Type 27 (flat) hub profile and rated to 13,300 RPM, this 4.5-inch disc combines grinding and surface blending into a single pass. Heavyweight polyester-backed flaps carry alumina zirconia mineral with a grinding aid, delivering more cutting power than standard aluminum oxide across ferrous and non-ferrous metal types. It is sized and rated for use with standard 4.5-inch angle grinders common on fabrication floors and job sites.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for heavy-duty metalworking tasks including weld removal, beveling, and sharp-edge work on structural steel, stainless steel, and other metal substrates. The 60-grit cut is coarse enough for aggressive stock removal while leaving a blended finish that reduces or eliminates secondary finishing steps. It is sold individually and used by metal fabricators, ironworkers, pipefitters, and welders in both shop and field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlumina zirconia mineral with grinding aid cuts faster than aluminum oxide on all metal types\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile suits flat surface and slight contour grinding\u003c\/li\u003e\n\u003cli\u003e60 grit removes stock aggressively while blending surface finish in one step\u003c\/li\u003e\n\u003cli\u003eHeavyweight polyester backing extends disc life under sustained high-pressure use\u003c\/li\u003e\n\u003cli\u003eRated to 13,300 RPM for compatibility with standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement disc for standard 4.5-inch angle grinders accepting Type 27 flap discs with a 7\/8-inch arbor hole, suitable for metalworking applications requiring coarse-grit stock removal and surface blending.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified operator following grinder and disc manufacturer safety guidelines. Verify the grinder's maximum RPM rating meets or exceeds the disc's 13,300 RPM rating before mounting. Inspect the disc for damage before each use and never use a disc that shows signs of delamination or cracking. Always use the appropriate guard and personal protective equipment including eye and face protection when operating angle grinders.\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 27 (Flat)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 13,300 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Alumina Zirconia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Heavyweight Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.26 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010363143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344051700018,"sku":"7010363143","price":115.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533365.jpg?v=1782027879","url":"https:\/\/voomisupply.com\/products\/3m-7010363143-flap-disc-577f-4-5-in-60-grit-t27-alumina-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
