Built around an aluminum oxide abrasive with a vitrified bond, this wheel measures 14 inches in diameter, 1-1\/2 inches thick, and carries a 5-inch arbor hole to fit standard surface and cylindrical grinder spindles. The 46-grit, coarse-grade construction paired with an I hardness code delivers aggressive material removal while maintaining enough wheel integrity for controlled, repeatable surface finishes. Rated at a maximum of 1800 RPM, it is sized for heavy-duty production grinding applications. Wheel color is white and the abrasive is semi-friable, supporting consistent self-dressing behavior during use.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and use on CNC cutting tool machines. Typical applications include soft carbon steels, tool steels, and super alloys. The non-porous, non-tapered, non-recessed Type 1 flat profile makes it straightforward to mount and dress on production grinding equipment. The specification code 38A46-IVBE identifies the exact abrasive blend and bond formulation, which is useful when cross-referencing to plant grinding specs or replacement records. Wheel weight is approximately 17.19 pounds, so proper handling equipment is recommended during mounting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive, semi-friable — supports consistent self-sharpening during grinding passes\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigidity and thermal stability at operating speeds\u003c\/li\u003e\n  \u003cli\u003e46 grit, coarse grade — suitable for high-stock-removal operations on steel and super alloys\u003c\/li\u003e\n  \u003cli\u003eI hardness code (medium) balances wheel wear rate against workpiece finish requirements\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel, no recess, no taper — fits standard surface and cylindrical grinder arbors with a 5-inch hole\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 1800 RPM — verify machine RPM before mounting\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.

Always ring-test the wheel for cracks before mounting and never exceed the rated maximum RPM of 1800. Power down and lock out the grinder before removing or installing any wheel. Use proper blotters and flanges matched to the wheel diameter and arbor size, and dress the wheel with an appropriate dressing tool before the first grinding pass.\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\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\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-IVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\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\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17.19 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: 66253364090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544472092978,"sku":"66253364090","price":439.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4467cb3ebd13c3c8b2aedb4693b42ed.jpg?v=1785927263","url":"https:\/\/voomisupply.com\/products\/norton-66253364090-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
