Built from aluminum oxide abrasive with a coarse 46-grit rating and J hardness code, this wheel delivers aggressive stock removal while maintaining dimensional control. The vitrified bond provides rigidity and porosity management suited to wet or dry surface grinding operations. At 13.85 pounds and a maximum operating speed of 2070 RPM, this wheel is engineered for use on dedicated surface and cylindrical grinders. Licensed grinding technicians and tool-room machinists are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is sized at 12 inches in diameter, 2 inches thick, with a 5-inch arbor hole, making it compatible with medium to large surface grinders and cylindrical grinders. The two-sided recess configuration features a recess depth of 0.5 inches and a recess diameter of 7.5 inches. Material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The semi-friable aluminum oxide grain self-sharpens under load, reducing glazing on harder alloys and extending wheel life between dressings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain rated semi-friable for self-sharpening performance on hard and soft steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides consistent cutting action and structural stability at operating speed\u003c\/li\u003e\n  \u003cli\u003eCoarse 46-grit, J hardness (medium hardness rating) for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eType 7 two-sided recessed configuration with 7.5-inch recess diameter and 0.5-inch recess depth\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 2070 RPM — confirm machine speed before mounting\u003c\/li\u003e\n  \u003cli\u003eGray, non-porous, non-tapered wheel construction in the 32A series specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the 2070 RPM maximum operating speed marked on the wheel. Power down and lock out the grinder before installing or removing the wheel, and use proper flanges and blotters rated for the arbor size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A46-JVBE\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\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\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: 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\u003eRecess Type\u003c\/strong\u003e: Two-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\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: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.85 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: 66253263483\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538375868722,"sku":"66253263483","price":582.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc86584a04cbdbea7bad30115eeb4f2e.jpg?v=1785823859","url":"https:\/\/voomisupply.com\/products\/norton-66253263483-surface-grinding-wheel-46-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
