Built with 32A aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action on surface grinders and cylindrical grinders alike. At 7 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, it mounts to standard spindles without modification. The 60-grit, I-hardness (medium grade) combination suits general-purpose grinding where material removal rate and workpiece finish must be balanced. Rated to 3600 RPM maximum.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for production and maintenance grinding applications in machine shops, tool rooms, and fabrication environments. It handles 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure promotes coolant flow and chip clearance, reducing heat buildup during extended grinding passes. The one-side recessed Type 5 geometry provides clearance for flanges and fixtures in tight setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e32A aluminum oxide abrasive grain for reliable cutting on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure improves coolant penetration and chip evacuation\u003c\/li\u003e\n\u003cli\u003eType 5 one-side recessed profile with 3-inch recess diameter and 1\/2-inch recess depth for fixture clearance\u003c\/li\u003e\n\u003cli\u003e60 grit, medium grade (I hardness) delivers balanced material removal and surface finish\u003c\/li\u003e\n\u003cli\u003eRated 3600 RPM maximum for safe operation on standard surface and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003eSpecification code 32A60-IVBE for direct cross-reference and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the 3600 RPM maximum speed rating. Power down and lock out the grinder before changing wheels, and ensure flanges, blotters, and the arbor hole fit are correct before tightening. Allow the wheel to run at operating speed in a guarded position for at least one minute before bringing it into contact with the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Weight\u003c\/strong\u003e: 2.93 pounds\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 5 (One-Side Recessed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium (I Hardness)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\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: 66252942686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543467622706,"sku":"66252942686","price":122.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a15137487f4d85a344995ab1314d633.jpg?v=1785919085","url":"https:\/\/voomisupply.com\/products\/norton-66252942686-surface-grinding-wheel-60-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
