Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and open grain structure suited to production grinding environments. The wheel measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. A 46-grit coarse grade and I hardness rating make it well-matched for aggressive material removal on carbon and tool steels. Maximum operating speed is rated at 3600 RPM. Grinding technicians and tool-and-die professionals typically specify this wheel for flat surface work on manual and CNC surface grinders.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and job-shop settings. Typical applications include grinding hard carbon steels, soft carbon steels, and tool steels where a coarse cut rate is required. The vitrified bond provides structural rigidity and allows coolant penetration, making it suitable for wet or dry surface grinding operations. The 32A series designation (32AA46-IVTR) identifies this as a general-purpose aluminum oxide formulation optimized for steel alloys common in toolroom and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess — standard fitment on most surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain suited to hard and soft carbon steels and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure for coolant flow and chip clearance during grinding\u003c\/li\u003e\n  \u003cli\u003e46-grit coarse grade for high stock-removal rate on flat surfaces\u003c\/li\u003e\n  \u003cli\u003eI hardness code (medium) balances wheel wear rate against cutting efficiency on steel\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\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 power down and lock out the grinder before mounting or changing wheels. Inspect the wheel for cracks or chips before installation and perform a ring test; never mount a damaged wheel. Verify that the machine spindle speed does not exceed the wheel's 3600 RPM maximum rating before operation.\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 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: I (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\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\u003c\/strong\u003e: 32AA46-IVTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252938877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540238565682,"sku":"66252938877","price":118.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95977c38adb6dbabe304798ca9b1ffdb.jpg?v=1785849851","url":"https:\/\/voomisupply.com\/products\/norton-66252938877-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
