Built with alumina zirconia mineral bonded to heavyweight polyester-backed flaps, this disc delivers aggressive stock removal alongside a blended finish without switching tools or abrasives. At 7 inches in diameter and 40 grit, it is engineered for heavy-duty tasks including weld removal, beveling, and sharp-edge work. The Type 27 (T27) depressed-center profile suits flat and slightly contoured work surfaces. Licensed trades and fabrication shops working with structural steel, stainless, and other hard metals will find this disc a reliable production tool.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for use in fabrication, structural steel work, shipbuilding, pipeline, and heavy manufacturing environments. The quick-change hub design reduces disc changeover time on compatible angle grinders, making it practical for high-volume grinding operations. Applications include weld bead removal, edge chamfering, beveling, and general surface conditioning on ferrous and non-ferrous metals. It is intended for professional metalworking use with angle grinders that accept 7-inch quick-change accessories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlumina zirconia mineral with grinding aid provides greater cutting power than standard aluminum oxide on all metal types\u003c\/li\u003e\n\u003cli\u003ePolyester-backed flaps rated for heavy-duty, high-pressure applications including beveling and sharp-edge work\u003c\/li\u003e\n\u003cli\u003eCombines grinding and blending into a single step, reducing total process time\u003c\/li\u003e\n\u003cli\u003eQuick-change hub design simplifies and speeds disc replacement on compatible grinders\u003c\/li\u003e\n\u003cli\u003eType 27 depressed-center profile for flat surface and weld grinding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders that accept 7-inch quick-change flap discs with a Type 27 profile.

Always power down and disconnect the grinder before mounting or removing a disc. Inspect the disc for damage before each use and confirm the grinder free speed does not exceed the disc maximum RPM rating. Eye protection, a face shield, and appropriate PPE are required during grinding operations.\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\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\u003eDisc Type\u003c\/strong\u003e: Type 27 (T27)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Style\u003c\/strong\u003e: Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.84 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051141309644\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: 7010363146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347350651186,"sku":"7010363146","price":6425.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533363.jpg?v=1782102274","url":"https:\/\/voomisupply.com\/products\/3m-7010363146-flap-disc-577f-type-27-7-inch-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
