Built around a white aluminum oxide abrasive in a vitrified bond matrix, this wheel delivers consistent cut rate and form retention across the full service life. The 46-grit coarse grade removes material quickly while the H hardness code keeps the wheel soft enough to shed dull grains and resist glazing. It measures 7 inches in diameter by 1 inch thick with a 1-1\/4 inch arbor hole and is rated to 3600 RPM. Licensed grinding machine operators and tool room machinists are the primary users of this product.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications in both production and tool room environments. Material applications include soft carbon steels, tool steels, and super alloys. The semi-friable aluminum oxide grain self-sharpens under load, making it a practical choice for precision work on heat-sensitive alloys where a sharp, free-cutting action is required. It is a non-porous, non-tapered, no-recess Type 1 flat wheel that mounts directly to standard surface grinder spindles with a 1-1\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive — semi-friable grain self-sharpens for consistent cut rate on steels and super alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid wheel structure and excellent form holding under precision grinding conditions\u003c\/li\u003e\n  \u003cli\u003e46-grit coarse grade for aggressive stock removal in surface and cylindrical grinding operations\u003c\/li\u003e\n  \u003cli\u003eH hardness (soft) rating reduces glazing risk and extends effective wheel life on harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum speed rating; verify spindle RPM does not exceed this value before mounting\u003c\/li\u003e\n  \u003cli\u003eSeries designation 38A46-HVBE ensures direct cross-reference to Norton 38A series specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-1\/4 inch spindle bore.

Always perform a ring test before mounting and confirm the machine spindle speed does not exceed the 3600 RPM wheel rating. Power down and lock out the grinder before changing wheels. Never force the arbor hole over the spindle flange or use makeshift bushings that alter the bore size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 38A46-HVBE\u003c\/li\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\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66252942534\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539135791410,"sku":"66252942534","price":94.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55399dff58368650613aa207df12aca5.jpg?v=1785835158","url":"https:\/\/voomisupply.com\/products\/norton-66252942534-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
