Built with Gemini aluminum oxide abrasive, this wheel measures 9 inches in diameter, 1\/4 inch thick, and has a 7\/8-inch arbor bore. It is rated to a maximum of 6,600 RPM, making it compatible with standard large-angle grinders. The aluminum oxide grain delivers consistent stock removal on ferrous metals including structural steel, weld seams, and bar stock. This wheel is a go-to consumable for ironworkers, pipefitters, fabricators, and maintenance mechanics working in heavy industrial and commercial environments.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is suited for use on ferrous metals such as carbon steel, cast iron, and structural steel profiles. Its depressed center Type 27 profile allows the operator to work at a low angle to the workpiece, improving surface contact and reducing fatigue on flat or curved stock. Typical applications include weld blending, surface conditioning, deburring, and flash removal. The 9-inch diameter provides an extended working surface compared to smaller-diameter wheels, allowing faster coverage on larger workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 depressed center profile for low-angle flat-surface grinding\u003c\/li\u003e\n\u003cli\u003eGemini aluminum oxide abrasive grain for consistent, aggressive metal removal\u003c\/li\u003e\n\u003cli\u003e9-inch diameter with 1\/4-inch thickness for extended grinding contact\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor bore fits standard large-angle grinder spindles\u003c\/li\u003e\n\u003cli\u003eRated to 6,600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for ferrous metal grinding applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for large-angle grinders accepting a 9-inch Type 27 wheel with a 7\/8-inch arbor bore and a maximum spindle speed of 6,600 RPM or lower.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting and operation must comply with ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI guidelines. Ensure the grinder is disconnected from power before mounting or removing any wheel. Never exceed the 6,600 RPM maximum speed rating marked on the wheel, and always use the appropriate guard and personal protective equipment during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27 Depressed Center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Gemini Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Metal Grinding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Bore\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 6,600 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 662530-48991\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51343895101746,"sku":"662530-48991","price":234.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310537051.jpg?v=1782025424","url":"https:\/\/voomisupply.com\/products\/norton-662530-48991-type-27-grinding-wheel-9x1-4x7-8","provider":"Voomi Supply","version":"1.0","type":"link"}
