Measuring 7 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, this wheel carries a 46-grit coarse grade and an H hardness code, placing it in the softer end of the hardness scale for efficient, cool cutting. A maximum operating speed of 3600 RPM is marked on the wheel. The vitrified bond and porous structure allow coolant penetration and chip clearance, reducing heat buildup during extended surface grinding operations. Machinists and tool-and-die professionals specify this wheel for production and maintenance grinding work.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. It performs across a broad range of materials including 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its coarse grit makes it well matched to aggressive material removal passes where surface finish is secondary to stock removal rate. The wheel ships as a single unit and is identified by the specification designation 32A46-HVBE.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e46-grit coarse aluminum oxide abrasive for aggressive stock removal on steel, iron, and aluminum\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes coolant flow and chip ejection to reduce heat\u003c\/li\u003e\n\u003cli\u003eH hardness code provides a softer wheel action that releases dull grains and self-dresses efficiently\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile fits standard surface grinder and cylindrical grinder spindle configurations\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch arbor hole accommodates common spindle sizes found on production grinding machines\u003c\/li\u003e\n\u003cli\u003eSpecification designation 32A46-HVBE confirms Norton 32A aluminum oxide grain series\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.

Inspect the wheel for cracks or chips before mounting and perform a ring test. Always match the machine spindle speed to the wheel's 3600 RPM maximum and never exceed it. Power down and lock out the machine before changing wheels, and use the proper flanges and blotter papers 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: 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: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\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\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A46-HVBE\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\u003eWeight\u003c\/strong\u003e: 3.17 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: 66252942513\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543791599922,"sku":"66252942513","price":133.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8583c1a9c13f4305455da7af5318b12.jpg?v=1785921832","url":"https:\/\/voomisupply.com\/products\/norton-66252942513-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
