Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cutting action and thermal stability under sustained grinding loads. It measures 8 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole, and carries a coarse 46-grit rating with an I hardness code. Rated to 3,105 RPM, it is suited for tool rooms and production surface grinding where controlled material removal is the priority. The gray vitrified wheel is porous, which aids in coolant retention and heat dissipation during extended passes.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production 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 make it appropriate for aggressive stock removal rather than finish grinding. The wheel specification designation is 32A46-IVBE, part of the NORTON 32A Type 1 series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain — effective on a wide range of ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for coolant flow and heat control during heavy cuts\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade for efficient stock removal\u003c\/li\u003e\n\u003cli\u003eI hardness code (medium) balances wheel life against cutting aggression\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile fits standard surface and cylindrical grinder arbors\u003c\/li\u003e\n\u003cli\u003e3,105 RPM maximum speed rating\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.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels, and verify that the machine spindle speed does not exceed the wheel's 3,105 RPM maximum rating. Use proper flanges and blotters as specified by the grinder manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 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: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\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\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: 32A46-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253043713\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541141618994,"sku":"66253043713","price":119.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1daf7df0c22627260b802293ead8d06b.jpg?v=1785868891","url":"https:\/\/voomisupply.com\/products\/norton-66253043713-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
