Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on high-speed steel and similar tooling materials. The wheel measures 5 inches in diameter with a 1-3\/4 inch overall thickness and carries a J hardness code, placing it in the medium grade range. Rated to a maximum of 4,585 RPM, this non-porous, friable wheel is suited for controlled grinding where cool cutting action matters. It weighs 1.31 pounds and ships individually.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for bench or pedestal tool and cutter grinders used in machine shops, maintenance facilities, and industrial toolrooms. The Type 11 flaring cup profile allows face grinding on drill bits, end mills, reamers, and other rotary cutting tools. It is a standard choice for tool grinding tasks that require a medium-grit, medium-hardness aluminum oxide wheel where surface finish and edge geometry are the priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 11 flaring cup wheel profile suited for tool and cutter grinding operations\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, repeatable stock removal\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade with J hardness code for balanced cut rate and wheel life\u003c\/li\u003e\n\u003cli\u003eFriable grain structure promotes cool cutting and reduces heat buildup at the workpiece\u003c\/li\u003e\n\u003cli\u003eNon-porous construction maintains wheel integrity under standard dry grinding conditions\u003c\/li\u003e\n\u003cli\u003eRated to 4,585 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or spare Type 11 flaring cup grinding wheel for bench and pedestal tool and cutter grinders accepting a 1-1\/4 inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and dressing of grinding wheels should be performed by a qualified machine operator or maintenance technician following ANSI B11.9 and OSHA 1910.215 standards. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting, and never exceed the maximum RPM marked on the wheel or grinder, whichever is lower. Perform a ring test prior to installation and run the wheel at operating speed in a guarded position for at least one minute before applying it to the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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: J\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: 1-3\/4 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\u003eHub Diameter\u003c\/strong\u003e: 3-3\/4 inches\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: 4,585\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\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: 1.31 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: 66253269590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51749576147250,"sku":"66253269590","price":57.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/563abad396799b4a8fd71f5ce2ecbf8d.jpg?v=1788907842","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269590-type-11-grinding-wheel-60-grit-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
