Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and wheel integrity across sustained surface grinding operations. The wheel measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a 46-grit coarse grade for aggressive material removal. Hardness code I indicates a medium-hard wheel structure that holds its form under moderate grinding pressure. Rated at 2,485 RPM maximum, this wheel suits production-level surface grinding setups where dimensional accuracy and surface finish are both requirements.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. It is rated for use on 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Series 32A vitrified bond construction makes it a dependable choice for shops that cycle through material types without changing wheels. Licensed machinists and grinding specialists are the primary installers and operators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for consistent cut performance across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction provides rigidity and resistance to heat and coolant\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade rated for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant flow and chip clearance during operation\u003c\/li\u003e\n\u003cli\u003eMedium hardness (Code I) balances wheel life with consistent cut rate\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 straight profile for straightforward mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always ring-test the wheel for cracks before mounting and confirm the machine spindle RPM does not exceed the 2,485 RPM maximum rating stamped on the wheel. Power down and lock out the machine before mounting or removing the wheel. Never exceed the rated speed, and always use the correct flanges and blotters for the arbor size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\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\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: 2,485\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\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\u003eSeries Specification\u003c\/strong\u003e: 32A46-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.097 pounds\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: 66253160750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538928075058,"sku":"66253160750","price":277.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/042118108a3b2a8d26a7e12a194135dd.jpg?v=1785829938","url":"https:\/\/voomisupply.com\/products\/norton-66253160750-surface-grinding-wheel-46-grit-10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
