Built with white aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on tool steels, carbide-tipped tooling, and similar hard materials. The wheel runs at a maximum of 5,730 RPM and carries a K hardness code, indicating a medium-grade bond that holds abrasive grain firmly while still releasing dull grains to expose fresh cutting edges. At 46 grit, it performs coarse-to-medium material removal, making it a practical choice for reshaping cutting edges before finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on bench grinders and pedestal grinders in machine shops, tool rooms, and maintenance environments. The Type 11 (flaring cup) profile is commonly matched to surface and tool grinding machines where side-face contact is needed to true up and sharpen milling cutters, drills, lathe tools, and similar tooling. The vitrified bond construction supports cool cutting and dressing ease, which matters when maintaining close tolerances on resharpened tooling. Installation and operation are typically handled by machinists and maintenance technicians familiar with grinding wheel safety standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive for clean, cool cutting on tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond allows easy dressing and maintains wheel form\u003c\/li\u003e\n  \u003cli\u003eType 11 flaring cup profile for side-face grinding contact\u003c\/li\u003e\n  \u003cli\u003e46 grit for efficient coarse-to-medium stock removal\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) balances grain retention with self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eRated to 5,730 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use grinding wheel for bench grinders and pedestal tool grinders accepting a Type 11 cup wheel with a 1-1\/4 inch arbor hole and 4 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting and operation should be performed by qualified personnel following ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; do not use a wheel that does not emit a clear tone. Never exceed the maximum RPM stamped on the wheel or listed by the manufacturer, and always use the appropriate flanges and blotter washers.\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 11 (Flaring Cup)\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size (Arbor)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Marking\u003c\/strong\u003e: 38A46-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.804 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66243530378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543390224690,"sku":"66243530378","price":92.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6c3764074974cc98c3514cef4a1c7c4.jpg?v=1785917716","url":"https:\/\/voomisupply.com\/products\/norton-66243530378-type-11-grinding-wheel-4in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
