Built with an aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and free-cutting action across a range of industrial grinding applications. It measures 12 inches in diameter, 1 inch thick, and carries a 3-inch arbor hole. The 46-grit, G-hardness (coarse grade) specification places it in the working range for rapid material removal rather than fine finishing. Rated at a maximum of 2,070 RPM, it is sized for use on full-size surface and cylindrical grinding machines. Weighing 9.045 pounds, the wheel suits fixed-machine grinding rather than handheld use.\u003c\/p\u003e\u003cp\u003eThis wheel is a fit for production and maintenance grinding environments where operators work with hard and soft carbon steels, 400 series stainless steel, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, vitrified structure promotes coolant flow and chip clearance, helping reduce heat buildup during extended grinding passes. The 32A series designation identifies this as a standard NORTON aluminum oxide formulation for general-purpose ferrous grinding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess — mounts directly on straight-arbor machine spindles\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and wheel integrity under load\u003c\/li\u003e\n\u003cli\u003e46 grit, G hardness (coarse) — suited for rapid stock removal rather than finishing passes\u003c\/li\u003e\n\u003cli\u003ePorous structure promotes coolant penetration and chip evacuation to reduce thermal damage\u003c\/li\u003e\n\u003cli\u003e3-inch arbor hole fits standard surface and cylindrical grinder spindle configurations\u003c\/li\u003e\n\u003cli\u003eRated at 2,070 RPM maximum — verify machine speed before mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation — do not use a damaged wheel. Confirm the machine spindle speed does not exceed the 2,070 RPM maximum rating marked on the wheel before operating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A46-GVBEP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.045 pounds\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: 66253262840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543541317938,"sku":"66253262840","price":361.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1dc2a0087b7c7d2abf35e23dc57dba5.jpg?v=1785920162","url":"https:\/\/voomisupply.com\/products\/norton-66253262840-surface-grinding-wheel-46-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
