Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent, controlled cutting action across a wide range of materials. The wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a coarse 46 grit rating with a K hardness code — a medium-hardness wheel suited for aggressive stock removal without loading. Rated to a maximum of 2070 RPM, it is designed for professional use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Installation and dressing are performed by trained grinding machine operators.\u003c\/p\u003e\u003cp\u003eThis wheel is well-suited for production and job-shop grinding environments where consistent material removal rates are required. Rated applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified structure provides free chip clearance and reduces heat buildup at the workpiece, making it appropriate for both wet and dry surface grinding operations where surface finish and dimensional control are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for broad metal compatibility including stainless, tool steel, cast iron, and aluminum\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes chip clearance and cooler cutting action\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for aggressive stock removal applications\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) resists loading while releasing dull grains efficiently\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile fits standard surface grinder spindles with a 3-inch arbor hole\u003c\/li\u003e\n\u003cli\u003eSeries 32A specification — gray, non-tapered, no-recess design for direct spindle mounting\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 requiring a Type 1 straight wheel with a 3-inch arbor hole and 12-inch diameter.

Before mounting, inspect the wheel for cracks or chips using the ring test — do not use a damaged wheel. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 2070 RPM maximum rating stamped on the wheel. Always use the correct flanges and blotters for the arbor size, and run the wheel at operating speed with guards in place for at least one minute before presenting work.\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\u003eArbor Hole Size\u003c\/strong\u003e: 3 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: K (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\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 (Straight)\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\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\u003eSeries Specification\u003c\/strong\u003e: 32A46-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.045 pounds\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: 66253262572\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543468409138,"sku":"66253262572","price":517.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a6e039adbba8cacf1ffd68bc848d18c.jpg?v=1785919111","url":"https:\/\/voomisupply.com\/products\/norton-66253262572-surface-grinding-wheel-46-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
