This wheel measures 4 inches in diameter with a 1.5-inch overall thickness and a 0.25-inch face width. The vitrified bond construction and 46-grit coarse cutting surface make it well suited for aggressive stock removal on ferrous metals and general shop grinding tasks. At a maximum rated speed of 5,730 RPM, it is appropriate for bench grinder and pedestal grinder setups. The K hardness code indicates a medium-grade wheel that releases abrasive grains at a controlled rate, supporting consistent cut action. Machinists, tool-and-die technicians, and maintenance tradespeople are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in industrial maintenance shops, tool rooms, and fabrication environments where controlled material removal is required on metal workpieces. The Type 11 flared-cup profile allows access to inside diameters, shoulders, and recessed surfaces that flat wheels cannot reach. It is a standard fit for bench and pedestal grinders equipped with a 1.25-inch arbor hole. Applications include sharpening tooling, deburring castings, and reconditioning worn tool edges in both residential shop and light commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 11 flared-cup profile for grinding recessed surfaces and inside diameters\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive material suited for ferrous metals and general-purpose grinding\u003c\/li\u003e\n  \u003cli\u003eVitrified bond for consistent abrasive grain exposure and controlled wear\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse cutting surface for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 5,730 RPM for standard bench and pedestal grinder use\u003c\/li\u003e\n  \u003cli\u003eFriable grain structure allows self-dressing action during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for Type 11 grinding wheels on bench and pedestal grinders with a 1.25-inch arbor hole and a maximum spindle speed at or below 5,730 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and wheel changes must be performed by a qualified technician following ANSI B7.1 safe-use standards for abrasive wheels. Disconnect and lock out power to the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test by tapping the wheel lightly with a non-metallic object to confirm it produces a clear tone. Never exceed the maximum RPM rating stamped on the wheel.\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\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: 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\u003eHub Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 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\u003eWheel Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,730\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\u003eWeight\u003c\/strong\u003e: 0.34 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: TRU-MAXX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253269573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51730056642866,"sku":"66253269573","price":37.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1e069a383742a431a8008e2a78df588.jpg?v=1788710951","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269573-type-11-grinding-wheel-4in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
