Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and long wheel life under continuous grinding loads. The wheel measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. At 60 grit and H hardness (medium grade), it strikes a balance between aggressive material removal and surface finish quality, making it a reliable choice for production and maintenance grinding applications. Rated to 3,600 RPM, it fits standard surface grinder spindles without modification.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. The porous, vitrified structure promotes coolant flow and chip clearance, reducing heat buildup during extended runs. The 32A60-HVBEP specification designates this wheel within NORTON's 32A series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and wheel integrity\u003c\/li\u003e\n\u003cli\u003e60 grit, H hardness (medium grade) for balanced stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and chip evacuation\u003c\/li\u003e\n\u003cli\u003eRated to 3,600 RPM for use on standard surface and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straight Type 1 profile fits most standard arbor flanges\u003c\/li\u003e\n\u003cli\u003eSpec designation 32A60-HVBEP for cross-referencing within the 32A series\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 perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and lockout the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3,600 RPM rating marked on the wheel. Use properly matched flanges and a blotter on each side of the wheel when mounting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\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: H\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A60-HVBEP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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\u003eWeight\u003c\/strong\u003e: 2.1 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: 66253043888\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543491412274,"sku":"66253043888","price":129.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/557cf21003ff65a057c1e7bc2ab242a9.jpg?v=1785919457","url":"https:\/\/voomisupply.com\/products\/norton-66253043888-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
