Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steel. The wheel measures 4 inches in diameter with a 1-1\/2 inch overall thickness and a 1\/2 inch face width, running at a maximum rated speed of 5,730 RPM. At 60 grit with K hardness (medium grade), it is well suited for moderate material removal while maintaining reasonable surface finish. This wheel is used by machinists, tool grinders, and maintenance techs working with bench or pedestal grinding equipment.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for dry grinding on tool and cutter grinders, bench grinders, and pedestal grinders accepting a 1-1\/4 inch arbor hole. The 38A60-KVBE specification designates a friable white aluminum oxide grain structure, which fractures cleanly to expose fresh cutting edges during use. It is a practical choice for sharpening cutting tools, grinding HSS tooling, and light surface grinding tasks in machine shops and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled grinding action\u003c\/li\u003e\n  \u003cli\u003eType 6 straight cup wheel geometry suited for face grinding on bench and pedestal grinders\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness (medium) for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eFriable grain structure fractures to self-dress, reducing glazing during use\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 5,730 RPM for safe operation on standard grinding equipment\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color indicates friable aluminum oxide grain, specification 38A60-KVBE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on bench grinders, pedestal grinders, and tool and cutter grinders equipped with a 1-1\/4 inch arbor.

Always power down and lockout the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test on vitrified wheels prior to use. Never exceed the maximum rated RPM of 5,730 stamped on the wheel, and always use appropriate eye and face protection during operation.\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 6 Straight Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 38A60-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\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: K\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: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 1\/2 inch\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\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\u003eWeight\u003c\/strong\u003e: 0.92 pounds\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: 66243530221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540532691250,"sku":"66243530221","price":80.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b7a599b922844d55963ad07e4be57c0.jpg?v=1785857662","url":"https:\/\/voomisupply.com\/products\/norton-66243530221-type-6-grinding-wheel-4-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
