Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cut rate and shape retention across extended use. It measures 8 inches in diameter, 3\/4 inches thick, with a 1-1\/4 inch arbor hole, and carries a 60 grit, J hardness (medium grade) rating. Maximum operating speed is 3600 RPM. The vitrified bond structure is porous, which promotes coolant flow and reduces heat buildup at the workpiece surface. This wheel is installed and dressed by machinists and grinding technicians in production and tool-room environments.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is suited for surface grinding applications on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The 60 grit and medium grade combination makes it appropriate for moderate material removal where surface finish is still a consideration. It fits standard 1-1\/4 inch arbor spindles common to bench-style and reciprocating surface grinders found in job shops and maintenance facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain — effective on ferrous metals including stainless, carbon, and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure promotes coolant penetration and reduces thermal load\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile — no recess, no taper, compatible with straight-spindle surface grinder setups\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade for balanced stock removal and workpiece finish\u003c\/li\u003e\n  \u003cli\u003eJ hardness code — medium wheel hardness supports consistent grain breakdown on harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed rated for safe use on standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips before mounting — perform a ring test by tapping the wheel gently and listening for a clear tone. Power down and lock out the grinder before installing or removing the wheel. Never exceed the 3600 RPM maximum speed rating marked on the wheel or its blotter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3\/4 inches\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\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\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253044171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540447330610,"sku":"66253044171","price":184.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0a18336e9dd25d7679a6482b2a408d6.jpg?v=1785855441","url":"https:\/\/voomisupply.com\/products\/norton-66253044171-surface-grinding-wheel-60-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
