It measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded in a vitrified matrix, delivering consistent cut rate and long wheel life. At 46 grit with a J hardness code (coarse grade, medium hardness rating), it is well suited for aggressive material removal on hard and soft carbon steels, stainless, and cast iron. The 32A46-JVBE specification identifies this as a standard Norton 32A Series wheel. Licensed grinding professionals and toolroom machinists are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for a maximum of 1800 RPM and is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, vitrified bond structure promotes chip clearance and coolant penetration, reducing heat buildup during extended grinding passes. Compatible material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is sold individually as a single-unit package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, repeatable cut rate\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium hardness rating) balances wheel life against cut aggressiveness\u003c\/li\u003e\n  \u003cli\u003ePorous structure promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel geometry — no recess, no taper\u003c\/li\u003e\n  \u003cli\u003eNorton 32A Series specification: 32A46-JVBE\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 perform a ring test before mounting and inspect the wheel for cracks or chips. Verify the machine spindle speed does not exceed the 1800 RPM maximum rating marked on the wheel. Use proper blotters and flanges rated for the wheel diameter, and never exceed the rated speed under any operating condition.\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\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: J\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\u003c\/strong\u003e: 32A46-JVBE\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\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.47 pounds\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: 66253363919\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539007930674,"sku":"66253363919","price":437.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32e776604acab794837db4cd1c30d116.jpg?v=1785832649","url":"https:\/\/voomisupply.com\/products\/norton-66253363919-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
