Built on an aluminum oxide abrasive with a vitrified bond, this 7-inch diameter wheel runs at a maximum of 3600 RPM and delivers consistent, medium-grade cutting action. The 60-grit specification and J hardness rating balance aggressive material removal with controlled surface finish. At 3\/4 inches thick with a 1-1\/4-inch arbor hole and a single-side recess of 1\/4 inch deep by 2-3\/4 inches in diameter, this wheel fits standard surface and cylindrical grinder spindles used in production and maintenance grinding applications.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface and cylindrical grinding operations in machine shops, tool rooms, and maintenance facilities. It performs across 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, making it well-matched to both wet and dry grinding setups on dedicated surface grinders and cylindrical grinders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 one-side recessed profile for clearance on compatible grinder spindle flanges\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive, 60 grit, medium grade for balanced cut rate and finish\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure aids coolant penetration and swarf evacuation\u003c\/li\u003e\n\u003cli\u003eJ hardness code provides medium wheel hardness suitable for a wide range of workpiece hardness levels\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSpecification code 32A60-JVBE identifies exact bond and abrasive formulation for reorder accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always perform a ring test before mounting and inspect the wheel for cracks or damage. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Mount with correct blotters and flanges; never force the wheel onto the arbor.\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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: 60\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-JVBE\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: 2.14 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: 66252942218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538971722034,"sku":"66252942218","price":114.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15b491718cb40df9f8aef89fdff8ffbd.jpg?v=1785831390","url":"https:\/\/voomisupply.com\/products\/norton-66252942218-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
