Built around an aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and predictable breakdown on hard and soft carbon steels as well as tool steels. It measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. The 60-grit, J-hardness (medium grade) specification suits general-purpose surface grinding where a balance of material removal and wheel life is required. Maximum operating speed is rated at 3600 RPM.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited to flat surface grinding applications in production and toolroom environments. It runs on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A Series vitrified bond structure is porous, which promotes coolant flow and chip clearance during extended grinding passes. Typical users include machinists, tool-and-die makers, and industrial maintenance technicians working with carbon and tool steel workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for consistent performance on hard and soft carbon steels and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure improves coolant retention and chip clearance\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness (medium grade) balances aggressive stock removal with controlled wheel wear\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\u003e3600 RPM maximum operating speed rating\u003c\/li\u003e\n  \u003cli\u003e32AA60-JVTR specification code for direct cross-reference and procurement\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 using the ring test before mounting, and never exceed the rated maximum RPM of 3600. Power down and lock out the machine before changing wheels. Use proper flanges and blotters as specified by the grinder manufacturer; do not use damaged or mismatched flanges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\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\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\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA60-JVTR\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: 66252938881\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540787167538,"sku":"66252938881","price":87.16,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae9463aa8de2efee9aa63eb9cc424038.jpg?v=1785863960","url":"https:\/\/voomisupply.com\/products\/norton-66252938881-surface-grinding-wheel-60-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
