It uses alumina zirconia mineral combined with a grinding aid to deliver faster stock removal than standard aluminum oxide discs across steel, stainless, and other metal types. At 7 inches in diameter with a 40-grit cut, it handles aggressive material removal while still leaving a blended surface finish. Heavyweight polyester-backed flaps give the disc extended service life under sustained load, making it a practical choice for weld removal, beveling, and sharp-edge work in a single pass.\u003c\/p\u003e\u003cp\u003eThis disc is suited for use on angle grinders in fabrication shops, structural steel work, pipeline work, and heavy manufacturing environments. Its quick-change design reduces downtime between disc swaps. The 40-grit rating makes it appropriate for initial grinding stages where fast cutting and some surface conditioning are needed simultaneously. Trade professionals working in metal fabrication, ironwork, and pipe fitting will find it fits standard high-pressure finishing workflows without requiring a separate blending step.\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\u003eFlap design combines grinding and blending into one step, reducing total tool changes\u003c\/li\u003e\n\u003cli\u003eHeavyweight polyester-backed flaps extend disc life under high-pressure use\u003c\/li\u003e\n\u003cli\u003e7 inch diameter at 40 grit suits weld removal, beveling, and sharp-edge applications\u003c\/li\u003e\n\u003cli\u003eQuick-change disc format simplifies replacement on angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on standard angle grinders accepting 7 inch flap discs in high-pressure metalworking applications including weld removal, beveling, and edge blending on steel and other metals.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFlap discs of this type are mounted and serviced by metalworking tradespeople and fabricators using angle grinders. Confirm the grinder is rated for the disc diameter and RPM before mounting. Power down and unplug or de-energize the grinder before changing discs. Always verify the disc is properly seated and the guard is in place before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Flap\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\u003eWeight\u003c\/strong\u003e: 0.68 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\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: 7010300168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342798029106,"sku":"7010300168","price":5917.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533411.jpg?v=1782006951","url":"https:\/\/voomisupply.com\/products\/3m-7010300168-flap-disc-577f-7-inch-40-grit-alumina-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
