Built with aluminum oxide abrasive and a vitrified bond, this wheel carries a coarse 46 grit rating and a K hardness code, placing it in the medium hardness range. It measures 14 inches in diameter, 2 inches thick, with a 5-inch arbor hole, and is rated to a maximum of 1800 RPM. At 22.92 pounds, this is a heavy-duty wheel suited for production grinding environments. The porous structure of the wheel promotes coolant flow and chip clearance during aggressive cuts. Licensed HVAC, machining, and toolroom professionals install and dress these wheels as part of regular surface grinder maintenance cycles.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is well suited for surface grinder and cylindrical grinder applications in industrial and toolroom settings. It performs across a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The wheel is also compatible with CNC cutting tool machines. Its coarse grit makes it a strong choice for rapid material removal rather than finish grinding. The gray, non-tapered, no-recess Type 1 profile fits standard surface grinder spindle configurations at the listed arbor size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for broad metal compatibility including stainless, carbon steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes chip clearance and coolant penetration\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade rated for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eK hardness code, medium hardness rating, balances wheel life and cut rate\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess and no taper fits standard surface grinder arbors\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 1800 RPM\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 inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the rated maximum RPM. Power down and lock out the grinder before mounting or removing the wheel. A proper blotter and flanges of the correct diameter must be used to seat the wheel safely on the spindle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 2 inches\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\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\u003eMaximum RPM\u003c\/strong\u003e: 1800\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22.92 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: 66253364509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542986326322,"sku":"66253364509","price":915.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cd36871b5ee054a47bd00b286fb1a46.jpg?v=1785913102","url":"https:\/\/voomisupply.com\/products\/norton-66253364509-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
