Measuring 12 inches in diameter and 1.5 inches thick with a 5-inch arbor hole, it runs at a maximum of 2070 RPM. The 32A aluminum oxide abrasive grain at 46 grit delivers coarse, fast stock removal, while the vitrified bond provides rigidity and porosity for efficient chip clearance. At 10.91 pounds, it is suited for stationary surface and cylindrical grinder setups where consistent cut rate and wheel life matter.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on 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. It is designed for use on surface grinders and cylindrical grinders in industrial, maintenance, and tool-room environments. The one-side recessed profile with a 7.5-inch recess diameter and 0.5-inch recess depth allows proper clearance for flanges on compatible spindle configurations, making it a practical choice for production and repair grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e32A aluminum oxide abrasive grain — coarse 46 grit for high material removal rate\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction with porous structure for efficient coolant flow and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed wheel profile with 7.5-inch recess diameter and 0.5-inch recess depth\u003c\/li\u003e\n  \u003cli\u003eI hardness code (medium) balances wheel life against cut rate on a wide range of metals\u003c\/li\u003e\n  \u003cli\u003eRated to 2070 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with both surface grinders and cylindrical grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders and cylindrical grinders.

Always power down and lockout the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and perform a ring test per ANSI standards. Never exceed the rated maximum RPM of 2070.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.5 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 Diameter\u003c\/strong\u003e: 7.5 inches\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 Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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\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\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\u003eSpecification Code\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\u003eWeight\u003c\/strong\u003e: 10.91 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: 66253263166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542918168882,"sku":"66253263166","price":489.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afb213df76f2a3e995bd8a9712c55038.jpg?v=1785910926","url":"https:\/\/voomisupply.com\/products\/norton-66253263166-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
