It measures 14 inches in diameter and 1.5 inches thick with a 5-inch arbor hole, making it sized for medium to large capacity surface and cylindrical grinders. The abrasive is aluminum oxide bonded in a vitrified matrix, designated by the specification code 32A46-IVBE. At 46 grit with an I hardness code and coarse grade classification, this wheel cuts fast on hard materials without loading quickly. It is installed and dressed by experienced grinding machine operators in industrial, maintenance, and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications across a broad range of materials. Rated material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Type 5 profile features a single-side recess 0.5 inches deep and 8 inches in diameter, reducing wheel weight while maintaining the structural integrity needed for production grinding passes. It is appropriate for both job shop and production floor use where consistent stock removal rates are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive in vitrified bond for durable, consistent cut on steels and irons\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade removes stock quickly with moderate surface finish\u003c\/li\u003e\n\u003cli\u003eType 5 single-side recessed profile — recess is 8 inches in diameter and 0.5 inches deep\u003c\/li\u003e\n\u003cli\u003eI hardness rating provides medium wheel hardness suited to a wide material range\u003c\/li\u003e\n\u003cli\u003ePorous structure assists in chip clearance and coolant retention during wet grinding\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed rated at 1800 RPM — do not exceed this rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders accepting a Type 5 wheel with a 14-inch diameter, 5-inch arbor hole, and 1.5-inch face width.

Before installation, inspect the wheel for cracks or chips using a ring test, and verify the machine spindle speed does not exceed the 1800 RPM maximum marked on the wheel. Power down and lock out the grinder before mounting or removing the wheel. Always use proper blotter gaskets between the wheel and flanges, and dress the wheel before the first pass to true the face and expose fresh abrasive.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 8 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\u003eSpecification Code\u003c\/strong\u003e: 32A46-IVBE\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\u003eWheel Color\u003c\/strong\u003e: Gray\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: 14.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66253364300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540125712690,"sku":"66253364300","price":659.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d65c67534d1dacef22b687520b5e40a.jpg?v=1785846373","url":"https:\/\/voomisupply.com\/products\/norton-66253364300-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
