It measures 8 inches in diameter and 1\/2 inch thick, with a 1-1\/4 inch arbor hole for standard surface grinder spindle mounting. The abrasive is aluminum oxide with a vitrified bond, a combination well suited to controlled, consistent cutting action. At 46 grit and H hardness (coarse grade), this wheel cuts aggressively while the vitrified bond resists loading. It is rated to 3600 RPM maximum and follows the manufacturer specification designation 32A46-HVBEP. Machinists, tool-and-die technicians, and grinding specialists are the primary installers and users of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding operations across a wide range of materials, including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse grit and porous structure make it well matched to applications requiring fast material removal rather than fine finishing. It is a common choice in job shops and production grinding environments where consistent cut rates on varied stock are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive provides durable, sharp cutting action across ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond resists loading and maintains wheel form during extended surface grinding passes\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade suited for aggressive stock removal applications\u003c\/li\u003e\n  \u003cli\u003eH hardness rating (soft-to-medium range) allows the wheel to shed dull grains and self-sharpen during use\u003c\/li\u003e\n  \u003cli\u003ePorous structure promotes coolant flow and chip clearance, reducing heat buildup at the workpiece\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch arbor hole fits standard surface and cylindrical grinder spindles without adapter in most configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the maximum rated speed of 3600 RPM. Use proper flanges and blotters as specified by the grinder manufacturer; do not over-tighten the spindle nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 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\u003eSeries 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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 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: 66253043883\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544656052530,"sku":"66253043883","price":122.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/584d369ea6963471a8e3a14f4b276494.jpg?v=1785932725","url":"https:\/\/voomisupply.com\/products\/norton-66253043883-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
