Built on a Type 29 conical profile, this 7-inch disc runs heavyweight polyester-backed flaps loaded with alumina zirconia mineral and a grinding aid. That combination delivers faster stock removal than standard aluminum oxide abrasives while simultaneously blending the surface, eliminating the need for a separate finishing step. At 80 grit, it fits between aggressive material removal and acceptable surface finish in a single pass. Weight is 0.54 pounds per disc.\u003c\/p\u003e\u003cp\u003eThis disc is suited for metal fabrication shops, structural steel work, and maintenance welding environments where operators need consistent performance on ferrous and non-ferrous metals. The Type 29 raised-hub geometry increases contact angle on flat and curved workpiece surfaces, making it effective for grinding welds flush and cutting bevels on plate and pipe. It is configured as a quick change disc, which reduces downtime between disc changes on supported quick change grinder systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlumina zirconia mineral with grinding aid cuts faster than aluminum oxide across multiple metal types\u003c\/li\u003e\n\u003cli\u003eHeavyweight polyester-backed flaps extend disc life under high-pressure grinding conditions\u003c\/li\u003e\n\u003cli\u003eFlap construction combines grinding and surface blending in one step, reducing total labor time\u003c\/li\u003e\n\u003cli\u003eType 29 conical profile improves contact angle on flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eQuick change mount design simplifies and speeds disc replacement\u003c\/li\u003e\n\u003cli\u003e80 grit balances aggressive material removal with a blended finish result\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a quick change flap disc replacement for angle grinders and die grinders equipped with a compatible quick change arbor system accepting 7-inch Type 29 flap discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified metalworking or fabrication personnel familiar with angle grinder safety procedures. Confirm the grinder RPM rating meets or exceeds the disc maximum RPM before mounting. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Always wear appropriate PPE including a face shield 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: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 29 (Conical)\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\u003eAttachment\u003c\/strong\u003e: Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051141309941\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: 7010300167\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345863442738,"sku":"7010300167","price":6425.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533342.jpg?v=1782065008","url":"https:\/\/voomisupply.com\/products\/3m-7010300167-flap-disc-577f-7-inch-80-grit-type-29","provider":"Voomi Supply","version":"1.0","type":"link"}
