Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form-holding throughout the grind cycle. It measures 8 inches in diameter, 0.5 inches thick, with a 1-1\/4 inch arbor hole. The 46-grit, I-hardness (coarse grade) specification positions it as a workhorse wheel for aggressive material removal rather than fine finishing. Rated at a maximum of 3,105 RPM, it suits standard surface grinder spindle speeds common in production and toolroom environments. The 32AA46-IVTR specification code confirms abrasive type, grade, structure, and bond for techs who cross-reference wheel specs directly.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications in both production shops and toolroom settings. It is rated for use on hard carbon steels, soft carbon steels, and tool steels, making it a practical choice for shops working across a range of ferrous workpiece materials. Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond structure provides good porosity, which aids in chip clearance and reduces heat buildup during extended grinding passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable performance on carbon and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction provides rigidity and consistent wheel breakdown\u003c\/li\u003e\n\u003cli\u003ePorous structure aids coolant retention and chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade suited for aggressive stock removal applications\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel geometry fits standard surface and cylindrical grinder flanges\u003c\/li\u003e\n\u003cli\u003e32AA46-IVTR specification code for precise cross-referencing and replacement verification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\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 removing wheels. Inspect the wheel for cracks or chips before installation using a ring test, and never exceed the maximum RPM stamped on the wheel or listed on the blotter. A proper wheel dressing pass should be performed after mounting to ensure concentricity and expose fresh abrasive.\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 (Straight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 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\u003eArbor Hole 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA46-IVTR\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\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Equipment\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\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: 66253038892\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540880556338,"sku":"66253038892","price":137.11,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c57fa5b91d9818397ede31ae7b7d84f.jpg?v=1785865283","url":"https:\/\/voomisupply.com\/products\/norton-66253038892-surface-grinding-wheel-8in-46-grit-type-1","provider":"Voomi Supply","version":"1.0","type":"link"}
