Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and good form retention throughout its service life. It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. Rated at a maximum of 3,600 RPM, it carries an I hardness code and a grain structure rating of 6, placing it in the medium-soft range for balanced cut aggressiveness and wheel longevity. The white aluminum oxide composition is semi-friable, allowing the wheel to self-sharpen under load.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinders and bench grinders used in metalworking shops, tool rooms, and maintenance environments. The 80-grit specification targets medium-finish stock removal where surface finish and dimensional accuracy both matter. It is a non-porous, vitrified-bond wheel with no recess, making it straightforward to mount on standard 1-1\/4 inch arbor spindles. Licensed machinists, toolmakers, and maintenance technicians in industrial and production settings are the typical installers and operators of this product.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess for simple, secure mounting\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive — semi-friable grain for self-sharpening action under load\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid form retention and consistent cut geometry\u003c\/li\u003e\n\u003cli\u003e80 grit delivers medium stock removal with a usable surface finish\u003c\/li\u003e\n\u003cli\u003eI hardness code (soft-to-medium range) balances wheel wear against cut efficiency on harder workpieces\u003c\/li\u003e\n\u003cli\u003eRated to 3,600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for Type 1 surface grinding wheels with a 7-inch diameter, 1\/2-inch thickness, and 1-1\/4-inch arbor hole on standard bench and surface grinders accepting that spindle size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation must be performed by qualified personnel following ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or removing any wheel. Conduct a ring test by tapping the wheel gently — a clear tone indicates an intact wheel; a dull thud indicates a crack and the wheel must be discarded. Never exceed the 3,600 RPM maximum speed rating marked on the wheel, and verify the machine spindle speed before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\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: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A80I6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 66253255900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51737400082738,"sku":"66253255900","price":40.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48dc51a4d016ee9bfbc89f81824445a6.jpg?v=1788788055","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255900-surface-grinding-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
