It measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The wheel uses aluminum oxide abrasive bonded with a vitrified bond system, delivering consistent cutting action and free-cutting performance at coarse stock removal rates. Rated at a maximum of 2070 RPM, the H hardness code and coarse 46-grit structure are matched to applications requiring aggressive material removal on hard and soft carbon steels as well as tool steels. The 32AA46-HVTRP specification identifies the full wheel formulation for procurement and maintenance records.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding operations in machine shops, toolrooms, and production grinding environments. It is compatible with surface grinders and CNC cutting tool machines. The coarse grit and soft-to-medium H hardness rating allow the abrasive grains to break down and self-dress effectively when working harder workpiece materials, maintaining cut rate across the grinding pass. It is a standard choice for toolroom operators and grinding machine operators working with carbon and tool steel workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable performance on hard and soft carbon steels and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction provides rigidity, porosity, and consistent grain exposure\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for high material removal rates\u003c\/li\u003e\n\u003cli\u003eH hardness rating allows effective self-dressing on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant flow and chip clearance during wet grinding\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 straight wheel geometry\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.

Before mounting, inspect the wheel for cracks using the ring test. Power down and lockout the grinder before changing wheels. Never exceed the 2070 RPM maximum speed rating marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\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\u003eMaximum RPM\u003c\/strong\u003e: 2070\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 (Straight)\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-HVTRP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\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\u003eFor Use With\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\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: 66253207703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541394653490,"sku":"66253207703","price":461.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96b189b7807da13aa6ef94f5581b28fc.jpg?v=1785874713","url":"https:\/\/voomisupply.com\/products\/norton-66253207703-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
