Built on a vitrified bond with 46-grit aluminum oxide abrasive and an I hardness code (medium), this wheel delivers a coarse cut with controlled breakdown suited to high-material-removal applications. It measures 7 inches in diameter, 1 inch thick, and carries a 1-1\/4 inch arbor hole with a one-side recess of 1\/2 inch depth and 3 inches diameter. Maximum operating speed is 3,600 RPM. Specification code 32A46-IVBE identifies the abrasive series. Licensed machinists, toolroom grinders, and industrial maintenance techs are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited to surface grinder and cylindrical grinder applications in production and toolroom environments. Rated material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46-grit structure makes it a strong choice for roughing cuts and rapid material removal rather than finish grinding passes. It performs well on both wet and dry setups where the grinder spindle speed does not exceed the rated 3,600 RPM.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e46-grit aluminum oxide abrasive for coarse, high-removal-rate grinding\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and free-cutting action across a wide material range\u003c\/li\u003e\n  \u003cli\u003eI hardness (medium) balances wheel life with consistent grain exposure\u003c\/li\u003e\n  \u003cli\u003eType 5 recessed profile (one-side recess, 3 inches diameter, 1\/2 inch deep) clears spindle flanges on surface and cylindrical grinders\u003c\/li\u003e\n  \u003cli\u003eRated for 400 Series stainless, carbon steels, tool steels, aluminum, and iron grades\u003c\/li\u003e\n  \u003cli\u003ePorous structure supports coolant flow and chip clearance during wet grinding\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 power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B11.9 or the grinder manufacturer guidelines. Never exceed the rated maximum speed of 3,600 RPM, and confirm spindle speed before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3 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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A46-IVBE\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: 2.93 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: 66252942690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541263089970,"sku":"66252942690","price":123.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8f24b19bc44c82c86a68c6e81b45243.jpg?v=1785871051","url":"https:\/\/voomisupply.com\/products\/norton-66252942690-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
