Built with aluminum oxide abrasive grain and a vitrified bond, it delivers consistent cutting action and open-pore structure that helps prevent loading during extended grinding passes. The wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and carries a coarse 46 grit rating with an I hardness code (medium wheel hardness). Maximum operating speed is 1,800 RPM. It is sized and specified for professional surface and cylindrical grinding applications in production and tool-room environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46 grit makes it well matched to roughing and aggressive material removal rather than finish grinding. The series designation 32A46-IVBE identifies the exact abrasive specification for cross-referencing with grinding wheel charts and machine setup sheets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, free-cutting action\u003c\/li\u003e\n  \u003cli\u003eCoarse 46 grit removes material aggressively — suited for roughing passes on steel and iron\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure reduces loading and heat buildup during extended use\u003c\/li\u003e\n  \u003cli\u003eI hardness code (medium) balances wheel wear rate with cutting efficiency across varied workpiece hardness\u003c\/li\u003e\n  \u003cli\u003eType 1 straight profile fits standard surface grinder and cylindrical grinder spindle setups\u003c\/li\u003e\n  \u003cli\u003eSeries specification 32A46-IVBE for precise technical reference and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always ring-test the wheel for cracks before mounting and verify that the machine spindle speed does not exceed the 1,800 RPM maximum rated speed of this wheel. Power down and lock out the grinder before changing wheels. Never force the wheel onto the spindle or exceed the rated arbor hole tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole 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: I (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1,800\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\u003eSeries Specification\u003c\/strong\u003e: 32A46-IVBE\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: 10.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253363915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538393497906,"sku":"66253363915","price":570.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686572b5628f7b632a7adcdcce73265b.jpg?v=1785824318","url":"https:\/\/voomisupply.com\/products\/norton-66253363915-surface-grinding-wheel-46-grit-14in","provider":"Voomi Supply","version":"1.0","type":"link"}
