Built around an aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rates and wheel integrity across extended grinding cycles. At 7 inches in diameter and 3\/4 inches thick with a 1-1\/4 inches arbor hole, this wheel fits standard surface grinder spindles. The 80 grit, medium-grade (Hardness Code I) construction balances aggressive material removal with a controllable finish. Rated to 3600 RPM maximum, it is suited for production and tool-room environments where dimensional accuracy is required. Licensed machinists, tool grinders, and CNC operators are the primary installers and users of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable material applications include 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, which is especially useful when working harder alloys or heat-sensitive workpieces. The gray, non-tapered, no-recess profile matches standard Type 1 wheel mounting hardware without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, durable cutting action\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade (Hardness Code I) for balanced material removal and surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile — no recess, no taper — for direct spindle mounting\u003c\/li\u003e\n\u003cli\u003ePorous construction promotes coolant penetration and chip evacuation\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum speed rating for surface and cylindrical grinder use\u003c\/li\u003e\n\u003cli\u003eSeries designation 32A80-IVBE confirms abrasive specification for procurement and replacement\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 requiring a Type 1, 7 inches diameter wheel with a 1-1\/4 inches arbor hole.

Always inspect the wheel for cracks or chips using the ring test before mounting, and confirm spindle RPM does not exceed the 3600 RPM maximum rating. Power down and lock out the machine before removing the existing wheel or installing this one. Never force the wheel onto the spindle arbor — the 1-1\/4 inches hole should seat freely without modification.\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\u003eWheel Type\u003c\/strong\u003e: Type 1\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: I\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\u003ePorous\u003c\/strong\u003e: Yes\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: 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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A80-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252941946\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544191664434,"sku":"66252941946","price":113.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4edd0dcaa49c25ec55db868a070b18c1.jpg?v=1785925502","url":"https:\/\/voomisupply.com\/products\/norton-66252941946-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
