It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond, producing a porous, gray wheel rated at 46 grit coarse grade with an H hardness code. Rated to a maximum of 3105 RPM, it is suited for controlled, high-contact grinding passes on surface grinders and cylindrical grinders. The vitrified bond offers consistent breakdown and cool cutting action, making it a reliable choice for production and toolroom environments. The wheel weighs approximately 2.09 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is well suited for material removal on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Licensed machinists, toolroom technicians, and industrial grinder operators are the primary users. The 32A series designation reflects a specific aluminum oxide grain formulation optimized for a broad range of metalworking applications in both production shops and maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess, standard for surface and cylindrical grinding setups\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent grain breakdown and cool cutting\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade suitable for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eH hardness (soft hardness rating) promotes free cutting action on hard, dense metals\u003c\/li\u003e\n\u003cli\u003ePorous structure aids coolant flow and chip clearance during wet or dry grinding\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 3105 RPM — do not exceed this rating\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 inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3105 RPM maximum rating stamped on the wheel. Dress the wheel with an appropriate diamond dresser before the first grinding pass to true the face and expose fresh abrasive.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\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: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3105\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\u003ePorous\u003c\/strong\u003e: Yes\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 32A46-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 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: 66253043712\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538802147634,"sku":"66253043712","price":114.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a4f7cae3deb2e5ab9eb2beee42b048d.jpg?v=1785826877","url":"https:\/\/voomisupply.com\/products\/norton-66253043712-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
