The wheel measures 7 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, a one-side recess measuring 2.75 inches in diameter and 0.5 inches deep. Aluminum oxide abrasive is bonded in a vitrified matrix rated at 3600 RPM maximum. The 46-grit, H-hardness (coarse grade) specification — designated 32A46-HVBEP — suits aggressive stock removal on ferrous and non-ferrous metals. Installers and tool room operators specify this wheel when cycle time and cut rate matter more than ultra-fine finish.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for production and maintenance grinding applications in both shop and industrial settings. Material applications include 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. The porous vitrified bond promotes coolant retention and chip clearance, reducing heat buildup during extended grinding passes on tough alloys and hardened steels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 recessed profile with one-side recess — 2.75 inches diameter, 0.5 inches deep — for clearance on recessed-hub flanges\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain (32A series) provides consistent cut rate on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure promotes coolant flow and reduces glazing\u003c\/li\u003e\n  \u003cli\u003e46 grit, H hardness (coarse grade) optimized for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed rated for standard surface and cylindrical grinder spindles\u003c\/li\u003e\n  \u003cli\u003eGray wheel color for quick visual identification of aluminum oxide vitrified type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Power down and lock out the grinder before mounting — never exceed the 3600 RPM maximum speed marked on the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test; do not mount a wheel that fails inspection. Use proper flanges and blotters; never force the wheel onto the arbor.\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: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2.75 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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A46-HVBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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\u003eWeight\u003c\/strong\u003e: 0.22 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: 66252942828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540937703730,"sku":"66252942828","price":124.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d23b7914aca5eda00f039c1ead8a2709.jpg?v=1785866167","url":"https:\/\/voomisupply.com\/products\/norton-66252942828-surface-grinding-wheel-46-grit-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
