Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steels. It measures 6 inches in diameter with a 3\/8-inch face width and accepts a 1-1\/4-inch arbor hole. Rated at 46 grit with a K hardness code and medium grade, it strikes a balance between cut rate and surface finish. Maximum operating speed is 3820 RPM. The wheel is white in color and non-porous, with a vitrified bond that resists heat buildup during extended grinding cycles.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for offhand tool grinding, cutter grinding, and bench or pedestal grinder use in tool rooms, machine shops, and maintenance environments. The Type 11 flaring cup profile is commonly used on tool and cutter grinders for sharpening milling cutters, reamers, and similar tooling. The 4-1\/2-inch hub diameter and 1-1\/4-inch bore fit standard tool grinder spindles. Aluminum oxide construction makes it appropriate for general-purpose grinding of high-speed steel and carbon steel tooling. Installation and use is typically performed by machinists, tool room technicians, or skilled maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 11 flaring cup profile for tool and cutter grinder applications\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut and thermal resistance\u003c\/li\u003e\n  \u003cli\u003e46 grit, K hardness, medium grade for balanced stock removal and finish\u003c\/li\u003e\n  \u003cli\u003e3820 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction reduces loading on ferrous tooling materials\u003c\/li\u003e\n  \u003cli\u003eFriable grain structure promotes self-dressing action during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for tool and cutter grinders accepting a 6-inch Type 11 cup wheel with a 1-1\/4-inch arbor bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wheel should be mounted and dressed by a qualified machinist or tool room technician following ANSI B7.1 safe mounting practices. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 3820. Power down and lock out the grinder before changing wheels, and use proper flanges and blotters as required by the machine manufacturer. Eye protection and a wheel guard must be in place before operating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 11 Flaring Cup\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 Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 4-1\/2 inches\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\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3820\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\u003eFriable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 66252838495\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543287791922,"sku":"66252838495","price":199.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01864984d55d16a9cfda8becf5a21283.jpg?v=1785916820","url":"https:\/\/voomisupply.com\/products\/norton-66252838495-type-11-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
