Constructed from white aluminum oxide abrasive with a vitrified bond, this wheel delivers a semi-friable cutting action that continually exposes fresh grain during use. It measures 8 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, and carries an H hardness rating with a grain structure of 12, placing it in the soft-to-medium range. Rated to 3600 RPM, it is suited for surface, cylindrical, and bench grinder applications where consistent material removal and workpiece finish quality are priorities.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders and compatible bench-mounted grinding machines in machine shops, tool rooms, and maintenance facilities. The 46-grit coarse grade makes it well suited for aggressive stock removal rather than fine finishing passes. It is a standard selection for machinists, tool and die makers, and maintenance technicians working with hardened steels and similar materials. The porous structure of the vitrified bond allows for effective coolant flow and heat dissipation during wet or dry grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for semi-friable, self-sharpening cutting action\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and allows porous coolant flow during operation\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade suited for aggressive stock removal on ferrous metals\u003c\/li\u003e\n\u003cli\u003eH hardness rating (soft range) reduces heat buildup and glazing risk\u003c\/li\u003e\n\u003cli\u003eType 1 straight-wheel profile with no recess for broad surface grinder compatibility\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type 1 replacement grinding wheel for surface grinders and bench grinders accepting an 8 inch diameter, 1\/2 inch thick wheel with a 1-1\/4 inch arbor hole bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation and dressing should be performed by qualified machinists or maintenance technicians familiar with ANSI B11.9 safety standards for grinding machines. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM of 3600. Ensure the machine spindle speed is confirmed before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\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: 12\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A46H12V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66253255436\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51750523765042,"sku":"66253255436","price":39.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/814028725a566000714bfba7d6611afe.jpg?v=1788916173","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255436-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
