Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action across a range of ferrous and general-purpose materials. The wheel measures 12 inches in diameter and 1-1\/2 inches thick with a 5 inch arbor hole, weighing 11 pounds. At 46 grit with a J hardness code, this is a coarse-grade, medium-hardness wheel suited to aggressive material removal while maintaining wheel integrity at rated speed. Machinists and grinding shop technicians are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on horizontal spindle surface grinders that accept a 12 inch Type 5 recessed wheel with a 5 inch hole. The one-side recess measures 7-1\/2 inches in diameter, which is a standard configuration for cup-style and recessed surface grinding applications in job shops, tool rooms, and production grinding environments. The semi-friable aluminum oxide grain continuously self-sharpens during use, making it well suited to general surface grinding on steel and similar ferrous workpieces where a coarse finish is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 recessed wheel with 7-1\/2 inch one-side recess for proper spindle and flange clearance\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain, semi-friable, promotes consistent self-sharpening during cuts\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and porosity control for stable stock removal rates\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive material removal applications\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium) balances grain retention with free cutting action\u003c\/li\u003e\n  \u003cli\u003eRated to 2705 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use grinding wheel for horizontal spindle surface grinders accepting a 12 inch diameter, 1-1\/2 inch thick, Type 5 recessed wheel with a 5 inch arbor hole and a 7-1\/2 inch one-side recess diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always ring-test the wheel before mounting and inspect for cracks or chips. Ensure the machine spindle speed does not exceed the 2705 RPM maximum rating marked on the wheel. Use correct flanges and blotters, and run the wheel under guard at operating speed for at least one minute before applying it to a workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5 (Recessed One Side)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 7-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46 (Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 5\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\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: 2705\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A46J5V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 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: 66253269540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51731122946354,"sku":"66253269540","price":128.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b6cfb2fcc99150aa5496a2649ba3ff4.jpg?v=1788727206","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269540-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
