It measures 12 inches in diameter, 1 inch thick, and carries a 5-inch arbor hole. Built with aluminum oxide abrasive and a vitrified bond, the wheel delivers consistent cutting action and open structure suited to coarse-grade material removal. Rated at a maximum of 2070 RPM, it is designed for use on surface grinders and cylindrical grinders in production and toolroom environments. The K hardness code indicates a medium wheel hardness rating, balancing grain retention with controlled breakdown during cut.\u003c\/p\u003e\u003cp\u003eThis wheel fits production grinding applications where coarse stock removal is required on hard and soft carbon steels, tool steels, 400 series stainless steel, aluminum, cast iron, ductile iron, and gray iron. It is suited to CNC cutting tool machines, cylindrical grinders, and surface grinders. The 32A series designation and vitrified bond make it a dependable choice for high-volume grinding operations where wheel integrity and cut consistency matter across a full shift.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable cutting action on steel, iron, and aluminum\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides structural rigidity and consistent grain exposure\u003c\/li\u003e\n\u003cli\u003eCoarse 46-grit rating optimized for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003ePorous structure aids coolant flow and chip clearance during cut\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straightforward Type 1 flat wheel geometry\u003c\/li\u003e\n\u003cli\u003eSpecification code 32A46-KVBE for precise cross-reference and ordering\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 power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum of 2070 RPM. Flanges must be clean and properly fitted to the 5-inch arbor bore before the wheel is secured.\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: 5 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A46-KVBE\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\u003eWeight\u003c\/strong\u003e: 7.97 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: 66253262573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542473572658,"sku":"66253262573","price":351.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5b8650f036c4ab00881d3348367313a.jpg?v=1785901222","url":"https:\/\/voomisupply.com\/products\/norton-66253262573-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
