Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on ferrous metals and general-purpose workpieces. The wheel measures 7 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. At 46 grit with an I hardness rating, it falls in the coarse-grade range, making it well suited for aggressive material removal while maintaining reasonable wheel life. Maximum operating speed is rated at 3600 RPM. The semi-friable grain and non-porous structure help maintain free-cutting action across a range of grinding tasks.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on stationary surface grinders and bench grinders in machine shops, maintenance facilities, and fabrication environments. It is a standard Type 1 straight wheel profile with no recess, compatible with machines accepting a 1-1\/4 inch arbor bore. The white aluminum oxide composition makes it appropriate for grinding tool steels, high-speed steels, and similar ferrous materials where heat-sensitive workpieces require a cooler-cutting abrasive. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary installers and users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, repeatable grinding performance\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade suited for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eI hardness rating with semi-friable grain for free-cutting action on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess for broad machine compatibility\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum operating speed rating\u003c\/li\u003e\n  \u003cli\u003eNon-porous grain structure helps resist loading on soft or ductile materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type 1 replacement grinding wheel for bench grinders and surface grinders accepting a 7 inch diameter wheel with a 1-1\/4 inch arbor hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting and dressing must be performed by qualified personnel following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using a ring test, and never exceed the rated maximum RPM of 3600. Use proper wheel flanges and blotters as required by the machine manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\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\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A46I6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66253255889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51729190027570,"sku":"66253255889","price":33.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa56f17df5b2ed4e205cfb461487a822.jpg?v=1788701683","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255889-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
