The abrasive material is silicon carbide with a vitrified bond, making it well-suited for grinding hard, brittle materials such as carbite tools, ceramics, and cast iron. The wheel carries a 60 grit, medium grade designation with a hardness code of I, balancing stock removal speed with surface finish quality. Rated to a maximum of 4,585 RPM, it is sized at 5 inches in diameter with a 1-3\/4 inch overall thickness and a 3-3\/4 inch hub diameter. Installed by machinists, tool-and-die technicians, and maintenance trades on compatible bench or pedestal grinders.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for bench and pedestal grinder use in tool sharpening, deburring, and precision surface grinding operations. The Type 11 cup form presents the abrasive face along the rim, which is appropriate for grinding drill bits, lathe tools, and similar cutting tools requiring flat or slightly contoured relief faces. The green silicon carbide composition and non-porous, vitrified bond structure deliver consistent material removal on hard substrates. It is a single-piece wheel sold in individual quantity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive with vitrified bond for hard, brittle material grinding\u003c\/li\u003e\n  \u003cli\u003eType 11 flaring cup profile optimized for tool sharpening and flat face grinding\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade with I hardness code for balanced stock removal and finish\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 4,585 RPM for standard bench and pedestal grinder spindles\u003c\/li\u003e\n  \u003cli\u003eNon-porous wheel construction resists loading on dense materials\u003c\/li\u003e\n  \u003cli\u003eGreen wheel color identifies silicon carbide composition for quick visual verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style Type 11 cup grinding wheel for bench and pedestal grinders accepting a 1-1\/4 inch hole arbor.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 guidelines. Never exceed the maximum RPM marked on the wheel or stated in documentation, and ensure the machine spindle speed rating does not exceed 4,585 RPM for this 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: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4,585\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1.75 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: 3.75 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\u003eWheel Color\u003c\/strong\u003e: Green\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: 1.31 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: 66253269794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51728462020914,"sku":"66253269794","price":119.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4a8b64c4644b7494b7a5cb2397e07ac.jpg?v=1788691576","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269794-type-11-grinding-wheel-5-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
