Built on an aluminum oxide abrasive with a vitrified bond, it delivers consistent cutting action and thermal stability across extended grinding cycles. The wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. At a 46 grit, coarse grade with an I hardness rating and a maximum operating speed of 2,070 RPM, it is suited for aggressive material removal where surface finish is secondary to throughput. Licensed machinists, tool-and-die technicians, and CNC grinding operators are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs well on hard carbon steels, soft carbon steels, and tool steels. The vitrified bond structure is rated porous, which promotes coolant flow and chip clearance during wet or dry grinding operations. Its coarse, medium-hardness profile makes it a practical choice for initial surface conditioning and heavy material removal passes in production grinding environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable performance on carbon and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and thermal resistance during grinding\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes chip clearance and coolant flow\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade suited for high material removal rates\u003c\/li\u003e\n\u003cli\u003eI hardness (medium) balances wheel wear with consistent cutting action\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 straight wheel geometry for broad machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always perform a ring test before mounting and inspect the wheel for cracks or chips. Never exceed the maximum operating speed of 2,070 RPM. Guard the wheel properly and allow it to run at operating speed for at least one minute before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA46-IVTR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I (Medium)\u003c\/li\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\u003eMaximum RPM\u003c\/strong\u003e: 2,070\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\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: 66253262054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539067961650,"sku":"66253262054","price":425.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c80199215af575fa4612afc7045288e5.jpg?v=1785834250","url":"https:\/\/voomisupply.com\/products\/norton-66253262054-surface-grinding-wheel-46-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
