It measures 7 inches in diameter with a 1\/4-inch thickness and mounts via a 5\/8-11 threaded hole. The abrasive material is aluminum oxide rated at 24 grit, placing it in the very coarse grade category — well suited for rapid stock removal, weld grinding, and surface prep on steel and ferrous metals. The resinoid bond holds the abrasive under load and resists heat buildup during extended use. Maximum operating speed is 8,600 RPM. This wheel is used by fabricators, ironworkers, and maintenance mechanics who need a durable, fast-cutting disc for heavy grinding applications.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use with angle grinders equipped with a 5\/8-11 spindle thread, which is the standard thread size on most 7-inch angle grinders. It is appropriate for residential shop work, commercial fabrication, and industrial maintenance environments. The Type 28 saucer-shaped profile increases the contact area at lower grinding angles, making it a practical choice when working on flat stock, structural steel, or weld beads where a shallow attack angle is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 28 depressed center profile for low-angle flat-surface grinding\u003c\/li\u003e\n  \u003cli\u003e24 grit aluminum oxide abrasive for very coarse, high-speed stock removal\u003c\/li\u003e\n  \u003cli\u003eResinoid bond construction for durability under continuous load\u003c\/li\u003e\n  \u003cli\u003e8,600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded mount fits standard 7-inch angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch wheel thickness for aggressive cutting depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders accepting a 7-inch, 5\/8-11 threaded grinding wheel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified personnel following the grinder manufacturer's instructions and applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the rated maximum RPM. Appropriate eye protection, face shield, and gloves are required during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 8,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Compatibility\u003c\/strong\u003e: Angle Grinder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252940149\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51717541101874,"sku":"66252940149","price":26.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4c3a9151ce5105e989e9c8e2698a8dc.jpg?v=1788542166","url":"https:\/\/voomisupply.com\/products\/norton-66252940149-type-28-grinding-wheel-7-in-24-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
