It measures 10 inches in diameter and 3\/4 inches thick, with a 3-inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded in a vitrified matrix, rated at a coarse 46 grit with G hardness. At a maximum operating speed of 2,485 RPM, it delivers consistent material removal on surface grinders, cylindrical grinders, and CNC cutting tool machines. Weighing 4.57 pounds, it fits standard spindle configurations common in machine shops and tool rooms. Licensed tradespeople and skilled machinists are the typical end users.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for medium-to-heavy stock removal on a range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its porous structure promotes coolant flow and chip clearance, making it practical for both wet and dry surface grinding setups. The 32A series designation identifies the specific aluminum oxide grain formulation, which is well-established in toolroom and production grinding environments. It performs in both horizontal and vertical spindle surface grinder configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for durability and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for efficient stock removal\u003c\/li\u003e\n\u003cli\u003eG hardness rating — soft wheel hardness releases dull grains and resists loading on hard workpieces\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant penetration and chip evacuation\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 2,485 RPM rated for safe use on standard surface and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 straight wheel geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, power down and lock out the grinder completely. Always ring-test the wheel for cracks before mounting and use the correct flange and blotter sizes for the arbor diameter. Never exceed the maximum operating speed of 2,485 RPM stamped on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 inches\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,485\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 1 (Straight)\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\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 32A46-GVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.57 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: 66253160283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544078352690,"sku":"66253160283","price":264.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/184198af7717299953fa3b0f1a9cbfcb.jpg?v=1785923754","url":"https:\/\/voomisupply.com\/products\/norton-66253160283-surface-grinding-wheel-10in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
