Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and form retention across extended grinding cycles. The wheel measures 14 inches in diameter, 1-1\/2 inches thick, with a 5-inch arbor hole, and is rated to a maximum of 1800 RPM. At 17 pounds, it is sized for production-grade surface and cylindrical grinding equipment. The 46 grit, coarse grade, H hardness combination makes it well-suited for aggressive material removal while maintaining a controlled wheel breakdown rate on softer and tool steel workpieces.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in shop and production environments. The aluminum oxide composition and semi-friable structure perform reliably on soft carbon steels, tool steels, and super alloys. The 38A series designation indicates a white aluminum oxide formulation optimized for heat-sensitive applications where workpiece burn is a concern. It is installed and dressed by grinding machine operators and tool room technicians working in metalworking, tooling, and precision machining settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel geometry with no recess — compatible with standard surface and cylindrical grinder spindle configurations\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade with H hardness code for aggressive stock removal on steel and alloy workpieces\u003c\/li\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive, semi-friable construction, helps reduce heat buildup on heat-sensitive materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond for consistent form holding and redressability over the wheel life\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered wheel — uniform structure throughout the thickness\u003c\/li\u003e\n  \u003cli\u003eSpecification code 38A46-HVBE identifies the precise wheel formulation for reorder and wheel dressing reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the machine before mounting or dismounting the wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the maximum rated speed of 1800 RPM. Use proper flanges and blotters as required, and allow the wheel to run at operating speed in a guarded position for at least one minute before applying it to the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 1-1\/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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\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\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-HVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\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\u003eFriable\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17 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: 66253313968\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542381003058,"sku":"66253313968","price":403.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac0213b3cc0383ca4ac485e2d55789eb.jpg?v=1785899165","url":"https:\/\/voomisupply.com\/products\/norton-66253313968-surface-grinding-wheel-46-grit-14in","provider":"Voomi Supply","version":"1.0","type":"link"}
