At 4 inches in diameter with a 1-1\/2 inch overall thickness and a 1\/4 inch face width, this wheel handles tool grinding, sharpening, and light stock removal tasks on ferrous metals. The aluminum oxide abrasive is vitrified-bonded, friable, and rated at a K hardness code with a medium grade — characteristics that allow the wheel to break down and self-dress during use. Maximum operating speed is 5,730 RPM. Machinists, tool-and-die workers, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis wheel fits standard bench and pedestal grinders equipped with a 1-1\/4 inch arbor hole. The 80 grit medium grade makes it well-suited for general-purpose tool sharpening and edge dressing where a moderate cut rate and a reasonably smooth finish are both required. The white aluminum oxide composition is appropriate for use on high-speed steels and other heat-sensitive tooling where minimizing burn is a priority. Hub diameter is 3 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 11 recessed wheel profile — 4 inches diameter, 1-1\/2 inch overall thickness, 1\/4 inch face width\u003c\/li\u003e\n\u003cli\u003e80 grit aluminum oxide abrasive — medium grade, K hardness code\u003c\/li\u003e\n\u003cli\u003eVitrified bond with friable structure for consistent self-dressing during use\u003c\/li\u003e\n\u003cli\u003eRated to 5,730 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eNon-porous white wheel — suited for heat-sensitive tool steels\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch arbor hole fits standard bench and pedestal grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on bench and pedestal grinders with a 1-1\/4 inch arbor, accepting a Type 11 recessed wheel at 4 inches in diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting and dressing must be performed by a qualified technician following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Before mounting, power down and lock out the grinder at the disconnect. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM marked on the wheel. Always use the supplied blotters and flanges and ensure the guard is reinstalled before running the machine.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size (Arbor)\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3 inches\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: K\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\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 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: TRU-MAXX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253269569\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51738331545906,"sku":"66253269569","price":37.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37e413cc0e21bb1767bebb6d020effe5.jpg?v=1788798334","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269569-type-11-grinding-wheel-4-in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
