Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and good wheel life on surface grinders, cylindrical grinders, and CNC cutting tool machines. It measures 12 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The 80-grit, J-hardness (medium grade) specification suits applications requiring a balance between material removal rate and surface finish quality. Rated at a maximum of 2070 RPM, it is well suited for production grinding environments where controlled wheel wear is a priority.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders and cylindrical grinders in both shop and production settings. It performs on a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified structure promotes coolant flow and chip clearance during extended grinding passes, making it a practical choice for production floors and tool rooms where wheel dressing intervals need to be predictable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for improved coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003e80 grit, J hardness (medium grade) balances stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess — fits standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eSpecification grade 32A80-JVBE for consistent lot-to-lot performance\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 2070 RPM\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 inspect the wheel for cracks or chips before mounting — ring-test per ANSI B7.1 guidelines. Confirm the spindle speed does not exceed the wheel's maximum rated RPM of 2070 before operation. Use proper blotters and flanges as required by machine manufacturer specifications.\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\u003eArbor Hole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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, No Recess)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A80-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\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\u003eWeight\u003c\/strong\u003e: 8.5 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: 66253262696\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538896322866,"sku":"66253262696","price":323.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f96605ae9c4686abd80849cc24f1f15.jpg?v=1785828974","url":"https:\/\/voomisupply.com\/products\/norton-66253262696-surface-grinding-wheel-12in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
