The 577F disc uses alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster stock removal than standard aluminum oxide abrasives on steel, stainless, and other metals. At 7 inches in diameter with a 36-grit cut rating, it handles aggressive material removal while leaving a blended finish in the same pass. Fabricators, welders, and metalworkers use this disc for weld removal, beveling, and sharp-edge work where both cutting speed and finish quality matter.\u003c\/p\u003e\u003cp\u003eThis disc is designed for angle grinders equipped with a quick-change attachment system, simplifying disc swaps in production and field settings. The Type 29 conical profile increases surface contact on flat and contoured workpieces, making it well suited for weld seam blending, edge chamfering, and heavy stock removal on structural steel, plate, and pipe. The quick-change hub eliminates the need for a wrench during disc changes, reducing downtime on high-volume grinding operations.\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 all metal types\u003c\/li\u003e\n\u003cli\u003eType 29 conical profile increases surface contact for efficient grinding on flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eHeavyweight polyester-backed flaps extend disc life under high-pressure applications\u003c\/li\u003e\n\u003cli\u003eCombines grinding and finish blending into a single pass, reducing process steps\u003c\/li\u003e\n\u003cli\u003eQuick-change hub design speeds disc replacement without a wrench\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flap disc for angle grinders configured with a compatible quick-change hub system accepting 7-inch Type 29 discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a trained metalworking professional or experienced operator familiar with angle grinder safety. Confirm the grinder is powered off and unplugged before mounting or removing any disc. Verify the grinder RPM rating meets or exceeds the maximum rated speed of the disc before use. Always use appropriate personal protective equipment including face shield, gloves, and hearing protection 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: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 29 (Conical 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\u003eAttachment Style\u003c\/strong\u003e: Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.7 x 7.7 x 6.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 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: 7010363157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347809272114,"sku":"7010363157","price":6425.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533350.jpg?v=1782114241","url":"https:\/\/voomisupply.com\/products\/3m-7010363157-flap-disc-577f-type-29-7-inch-36-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
