It measures 8 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, making it a standard fit for most bench and pedestal grinders in that size class. The wheel uses an aluminum oxide abrasive grain with a vitrified bond and carries a J hardness code, placing it in the medium hardness range. It is rated to 3600 RPM maximum operating speed. Grain structure is 6, and the abrasive is semi-friable, meaning it fractures at a controlled rate to maintain a sharp cutting edge through the grind cycle. Machinists, toolroom techs, and maintenance grinder operators are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding applications in job shops, toolrooms, and maintenance facilities. The 60 grit designation targets medium-stock-removal passes where surface finish is secondary to material removal rate. The non-porous, vitrified bond construction handles dry grinding well and holds form under moderate heat. The white aluminum oxide composition makes it appropriate for tool steels and hardened alloys where heat-sensitive workpieces require a cooler cut than standard brown aluminum oxide wheels provide.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 flat wheel profile for surface and bench grinder use\u003c\/li\u003e\n  \u003cli\u003e60 grit aluminum oxide abrasive for medium stock removal\u003c\/li\u003e\n  \u003cli\u003eJ hardness (medium) vitrified bond resists loading on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure self-sharpens during the grind cycle\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction suited to dry grinding operations\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum speed rating for safe bench and pedestal grinder use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for bench grinders and pedestal grinders with an 8-inch wheel capacity and a 1-1\/4 inch arbor bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWheel mounting should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always ring-test the wheel for cracks before mounting and power down the grinder completely before changing wheels. Use the correct blotter washers and flanges and never exceed the wheel's stated maximum RPM. Confirm the grinder spindle speed does not exceed 3600 RPM before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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\u003ePorosity\u003c\/strong\u003e: Non-Porous\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\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A60J6V31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 66253255466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51736333910322,"sku":"66253255466","price":36.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdfe0bf4c349bc4deb63106e813dc04f.jpg?v=1788777291","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255466-surface-grinding-wheel-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
