Built from aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent cut rate and long service life on surface grinders and cylindrical grinders. It measures 14 inches in diameter, 2 inches thick, with a 5-inch arbor hole. The 46-grit coarse grade and J hardness rating make it well-suited for aggressive material removal applications where surface finish requirements are secondary to stock removal rate. Maximum operating speed is 2,320 RPM. Wheel weight is 11.43 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is appropriate for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production shop and maintenance environments. Material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse grit and medium hardness rating allow the wheel to cut freely through tough alloys without glazing prematurely, making it a practical choice for high-volume grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent stock removal and wheel integrity\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade for aggressive material removal across a broad range of ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eJ hardness code with medium hardness rating resists glazing on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess — fits standard surface and cylindrical grinder arbors\u003c\/li\u003e\n\u003cli\u003eRated to 2,320 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eNon-porous construction for predictable performance across material applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks or chips using the ring test — do not mount a damaged wheel. Power down and lock out the grinder before changing wheels, and ensure the machine spindle speed does not exceed the 2,320 RPM maximum rating marked on the wheel. Always dress the wheel with an appropriate dressing tool before first use to true the face and expose fresh abrasive.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\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: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 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: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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\u003eSpecification Code\u003c\/strong\u003e: 46J8V32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\/Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.43 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: 66253246811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543352279346,"sku":"66253246811","price":282.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3dd13d10d047cb9aa9adcf451e35f09.jpg?v=1785916954","url":"https:\/\/voomisupply.com\/products\/norton-66253246811-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
