It features an aluminum oxide abrasive bonded with a vitrified bond system, producing a porous, free-cutting wheel structure rated at a medium grade with K hardness. At 7 inches in diameter, 1\/2 inch thick, and bored to 1-1\/4 inches, this wheel fits standard surface grinder and cylindrical grinder spindles. The 80 grit designation delivers a balance of material removal rate and surface finish quality, making it a reliable choice for production grinding on ferrous metals. Maximum operating speed is 3600 RPM.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for grinding hard carbon steels, soft carbon steels, and tool steels. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond offers good form holding and consistent cut rate across the face of the wheel, making it well suited to flat surface grinding operations in tool rooms, maintenance shops, and production grinding cells where tight tolerances on steel components are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive construction for effective grinding of ferrous and tool steel materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid wheel structure and predictable wear characteristics\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance during grinding\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade balances material removal and surface finish on steel\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) rating supports consistent performance across varied feed rates\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\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 and perform a ring test. Power down and lock out the grinder before mounting or removing any wheel. Never exceed the maximum operating speed of 3600 RPM 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\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\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\u003eGrit\u003c\/strong\u003e: 80\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: K\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: Blue\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 32AA80-KVTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\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: 66252938884\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541493416242,"sku":"66252938884","price":100.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6de49f5983bcb058aaa8e62fc5801739.jpg?v=1785877772","url":"https:\/\/voomisupply.com\/products\/norton-66252938884-surface-grinding-wheel-80-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
