Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and predictable wear characteristics. It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. The 60 grit, I hardness (medium grade) specification makes it well suited for aggressive material removal while maintaining acceptable surface finish on a wide range of workpiece materials. Weight is approximately 1.59 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and job-shop environments. Material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is appropriate for both maintenance shops and high-volume grinding operations where consistent wheel geometry and bond integrity are required. The series designation is 32A Type 1, which denotes a standard straight wheel profile with no recess and no taper.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for broad ferrous and non-ferrous material compatibility\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid support for precise stock removal and consistent wheel form\u003c\/li\u003e\n  \u003cli\u003e60 grit, I hardness (medium grade) balances cut rate and surface finish\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance during wet or dry grinding\u003c\/li\u003e\n  \u003cli\u003eType 1 straight profile with no recess — mounts directly to standard surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed rated for safe use on compatible machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks or chips using the ring test per ANSI B7.1 standards. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Always use proper wheel flanges and a blotter on each side of the wheel as required by applicable safety standards.\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess, No Taper)\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\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\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 32A60-IVBE\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: 66252940880\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540148977970,"sku":"66252940880","price":100.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43d57c9e43b806a321b7df316bf752d9.jpg?v=1785847144","url":"https:\/\/voomisupply.com\/products\/norton-66252940880-surface-grinding-wheel-60-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
