Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal with controlled wear. It measures 4 inches in diameter with a 1-1\/2 inch overall thickness and a 1\/4 inch face width. Rated at a maximum of 5,730 RPM, it carries an 80 grit, K hardness (medium grade) specification — designated 38A80-KVBE. Friable aluminum oxide construction allows the wheel to self-dress as it cuts, maintaining a sharp cutting face throughout use. Tool grinders, machinists, and maintenance technicians are the typical users of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for precision tool grinding applications including drill grinding, cutter grinding, and surface reconditioning on bench or pedestal grinders. The Type 11 flaring cup profile makes it appropriate for face grinding and contoured tool edges. The 80 grit rating positions this wheel for medium stock removal and light finishing passes rather than aggressive rough grinding. The 1-1\/4 inch hole fits standard arbor sizes common on bench grinders used in machine shops, maintenance facilities, and tool rooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 11 flaring cup profile for face grinding and tool reconditioning\u003c\/li\u003e\n\u003cli\u003eWhite aluminum oxide abrasive — friable grain for self-dressing, sharp cutting action\u003c\/li\u003e\n\u003cli\u003eVitrified bond for dimensional stability and consistent performance\u003c\/li\u003e\n\u003cli\u003e80 grit, K hardness (medium) — designation 38A80-KVBE\u003c\/li\u003e\n\u003cli\u003e5,730 RPM maximum rated speed\u003c\/li\u003e\n\u003cli\u003eNon-porous structure for clean, controlled material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on bench and pedestal grinders accepting a 1-1\/4 inch arbor hole, commonly used for tool grinding and cutter sharpening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting — do not use a damaged wheel. After mounting, run the grinder at operating speed with a guard in place for at least one minute before applying the wheel to a workpiece, following ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\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\u003eSpecification Designation\u003c\/strong\u003e: 38A80-KVBE\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\u003eFriable\u003c\/strong\u003e: Yes\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66243530395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540617658674,"sku":"66243530395","price":75.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/446adb1bbaac62759c5680d106380796.jpg?v=1785860201","url":"https:\/\/voomisupply.com\/products\/norton-66243530395-type-11-grinding-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
