It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and carries a 46 grit coarse abrasive rating with an H hardness code. The wheel is constructed from aluminum oxide abrasive bonded in a vitrified bond matrix, designated by the manufacturer specification 32A46-HVBEP. This combination delivers consistent, free-cutting action during surface and cylindrical grinding operations. The wheel is rated for a maximum spindle speed of 3600 RPM. Licensed HVAC, metalworking, and toolroom technicians install and dress this type of wheel as part of routine machine maintenance and production grinding work.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is suited for surface grinding applications on a range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use on CNC cutting tool machines, cylindrical grinders, and surface grinders in both production and toolroom environments. The coarse 46 grit is selected when higher stock removal rates are needed rather than fine surface finish, making it appropriate for rough grinding passes and material breakdown in industrial and job shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive provides durable, free-cutting performance on ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction allows for efficient chip clearance and consistent wheel form retention\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade suited for aggressive stock removal in surface and cylindrical grinding\u003c\/li\u003e\n  \u003cli\u003eH hardness code indicates a soft-to-medium grade that releases abrasive grains before glazing occurs\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess and no taper — mounts directly to standard arbor flanges\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed rated for use on common surface grinder spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always shut down and de-energize the grinder and allow the spindle to come to a complete stop before removing or mounting a wheel. Inspect the wheel for cracks or damage using a ring test before mounting, and never operate above the rated maximum RPM stamped on the wheel or packaging. A proper wheel guard must be in place before the machine is powered on.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Specification\u003c\/strong\u003e: 32A46-HVBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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: 66252941205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539476644146,"sku":"66252941205","price":101.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6fc42ca0b917d04ce9aa89dcf41a228.jpg?v=1785841082","url":"https:\/\/voomisupply.com\/products\/norton-66252941205-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
