Built with an aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steel. It measures 4 inches in diameter with a 1.5-inch overall thickness and a 0.25-inch face width. The J hardness code and 46 grit rating place it in the coarse-to-medium cut range, making it well suited for reshaping and reconditioning cutting tools. Rated to 5,730 max RPM, it fits standard bench grinders and pedestal grinders used in tool rooms and maintenance shops. Weight is 0.34 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for bench grinder and pedestal grinder setups where tool grinding or offhand grinding is performed. The Type 11 cup profile allows access to rake faces, relief angles, and other geometry on drill bits, lathe tools, milling cutters, and similar tooling. It is a non-porous, friable wheel, meaning it self-dresses during use to expose fresh abrasive grain, reducing loading on softer tool steels. Typical users include machinists, tool-and-die technicians, and maintenance professionals who recondition tooling in-house.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 11 flaring cup profile for tool grinding and angle access\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut and form retention\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse-medium cut suitable for stock removal and tool reconditioning\u003c\/li\u003e\n  \u003cli\u003eFriable grain structure promotes self-dressing and reduces glazing\u003c\/li\u003e\n  \u003cli\u003eNon-porous white wheel resists loading on ferrous and tool steel workpieces\u003c\/li\u003e\n  \u003cli\u003e5,730 max RPM rating compatible with standard bench and pedestal grinders\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 grinders and pedestal grinders with a 1.25-inch arbor hole accepting a 4-inch diameter wheel rated to 5,730 RPM or lower.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and wheel mounting should be performed by a qualified machinist or maintenance technician following ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the marked maximum RPM. Use the correct flanges and blotters as specified by the grinder manufacturer.\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 Flaring Cup\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\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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\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: 66253269560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51728743924018,"sku":"66253269560","price":37.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dbe0296bab61afed49c0a1a5f9f285e.jpg?v=1788695728","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269560-type-11-grinding-wheel-4-in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
