Built with an aluminum oxide abrasive and a vitrified bond, this wheel measures 8 inches in diameter by 1\/4 inch thick with a 1-1\/4 inch arbor hole. The 46-grit coarse grade removes material aggressively while the H hardness rating keeps the wheel from loading on harder alloys. Rated to 3105 RPM, it is suited for production-level grinding on surface grinders and cylindrical grinders in machine shops and tool rooms. Grinding wheel replacement is a routine task for machinists and tool-and-die tradespeople.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous structure of the wheel promotes coolant flow and chip clearance during wet or dry surface grinding operations, reducing heat buildup on heat-sensitive workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled stock removal\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade suited for aggressive material removal passes\u003c\/li\u003e\n\u003cli\u003eH hardness rating (soft classification) helps prevent glazing on harder steels\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure improves coolant flow and chip evacuation\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess, compatible with standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eSpecification designation 32A46-HVBE for direct cross-reference to Norton series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks using the ring test — do not mount a cracked or chipped wheel. Power down and lock out the grinder before changing wheels, and always use the correct flanges and blotters for the arbor size. Do not exceed the 3105 RPM maximum speed rating under any circumstances.\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\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: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 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: H\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: 3105\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\u003eSpecification\u003c\/strong\u003e: 32A46-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.05 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: 66253043412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538996396338,"sku":"66253043412","price":103.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f478666030414f5e7b894d1d9aa408c3.jpg?v=1785832228","url":"https:\/\/voomisupply.com\/products\/norton-66253043412-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
