Manufactured from aluminum oxide abrasive and bonded with a vitrified bond, it delivers consistent cut rates and controlled breakdown across demanding grinding applications. The wheel measures 7 inches in diameter, 3\/4 inches thick, and carries a 1-1\/4 inch arbor hole. At 46 grit with a G (Coarse) hardness rating, it is suited to aggressive material removal where surface finish is secondary to cut rate. Maximum operating speed is 3600 RPM. Grinding machinists and tool room technicians are the primary installers of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous structure of the vitrified bond helps clear swarf and reduce heat buildup during extended grinding passes, making it practical for both production and toolroom environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable performance on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure aids swarf clearance and reduces heat during grinding\u003c\/li\u003e\n\u003cli\u003e46 grit, G hardness (Coarse grade) for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel geometry with no recess — fits standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSeries 32A Type 1 specification: 32A46-GVBEP\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.

Before mounting, inspect the wheel for cracks using the ring test — never use a damaged wheel. Power down and lock out the grinder before changing wheels. Do not exceed the 3600 RPM maximum operating speed under any circumstances; verify the machine spindle speed before startup.\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: 3\/4 inches\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\u003eWheel Type\u003c\/strong\u003e: Type 1 (No Recess)\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\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: G\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: 3600\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: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A46-GVBEP\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: 66252942070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541998207282,"sku":"66252942070","price":113.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cb1c963cbc22835c99ea2e7b47d9433.jpg?v=1785889231","url":"https:\/\/voomisupply.com\/products\/norton-66252942070-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
