Built from aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent cutting action and dimensional stability under high-cycle conditions. It measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a 60-grit, medium-grade (Hardness Code I) specification. The vitrified bond structure is porous, allowing coolant penetration and heat dissipation during extended grinding operations. Rated to a maximum of 2,070 RPM, it is suited for surface and cylindrical grinding applications in professional machine shop environments.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on hard carbon steels, soft carbon steels, and tool steels. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A series vitrified aluminum oxide construction makes it a standard choice for toolroom and production grinding where flat, accurate surface finishes are required. The blue wheel color is characteristic of the NORTON 32A series designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for effective stock removal on carbon and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for coolant flow and thermal control\u003c\/li\u003e\n\u003cli\u003e60-grit medium grade (Hardness Code I) balances cut rate and surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel geometry with no recess and no taper for straightforward mounting\u003c\/li\u003e\n\u003cli\u003eRated at 2,070 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSeries designation 32AA60-IVTR for direct cross-reference ordering\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.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B11.9 guidelines. Never exceed the maximum operating RPM marked on the wheel, and ensure the machine spindle speed is confirmed before startup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 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: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,070\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\u003eSeries Specification\u003c\/strong\u003e: 32AA60-IVTR\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\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\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\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: 66253262078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540917158194,"sku":"66253262078","price":425.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bf6c4692252dc7e370ed1092cd3fde4.jpg?v=1785865792","url":"https:\/\/voomisupply.com\/products\/norton-66253262078-surface-grinding-wheel-60-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
