The wheel measures 4 inches in diameter with a 10 mm (approximately 0.39 inches) face width and an overall thickness of 50 mm (approximately 1.97 inches). It is manufactured from white aluminum oxide abrasive bonded with a vitrified bond, rated at 80 grit with a J hardness code (medium grade). The friable aluminum oxide grain breaks down to expose fresh cutting edges during use, making this wheel well suited for grinding high-speed steel and other tool steels. Licensed trade professionals and tool room technicians are the primary installers of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is used in bench grinder and pedestal grinder setups for tool room, maintenance, and production environments. It performs well on ferrous metals and is a standard choice for sharpening and reconditioning cutting tools such as drills, end mills, and lathe bits. The Type 6 straight-cup form allows access to flat faces and relief angles on tooling. It is appropriate for light to moderate stock removal at controlled feed rates. Both residential shop settings and light commercial tool rooms use this wheel type regularly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for cool, free-cutting action on tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent wheel form during grinding\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade suits finish grinding and light stock removal\u003c\/li\u003e\n\u003cli\u003eJ hardness (medium) helps the wheel release dull grains to maintain cut rate\u003c\/li\u003e\n\u003cli\u003eFriable grain construction extends usable wheel life on hard materials\u003c\/li\u003e\n\u003cli\u003e5,730 maximum RPM rating matched to standard bench grinder speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment Type 6 straight-cup grinding wheel for bench grinders and pedestal grinders equipped with a 20 mm arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation and dressing should be performed by a qualified technician following ANSI B7.1 safe-use standards. Always disconnect power and verify the machine is at a full stop before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM of 5,730. A proper wheel guard must be in place before operating the grinder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 6 Straight Cup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\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 (100 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1.97 inches (50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.39 inches (10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 0.79 inches (20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,730\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\u003eSpecification Code\u003c\/strong\u003e: 38A80-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.99 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: 66243530429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541146960178,"sku":"66243530429","price":97.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2619c6c3bcabcfc565269818bb326e0d.jpg?v=1785868972","url":"https:\/\/voomisupply.com\/products\/norton-66243530429-type-6-grinding-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
