Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steels. It measures 8 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. At 80 grit and K hardness (medium grade), it is suited for moderate material removal with a reasonably fine finish. The semi-friable grain structure helps the wheel self-dress during use, maintaining cut efficiency over its service life. Licensed machinists, tool and die makers, and skilled grinding technicians are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on horizontal spindle surface grinders in machine shops, toolrooms, and manufacturing environments. The Type 1 flat wheel profile is the standard configuration for reciprocating table surface grinding. It is appropriate for grinding carbon steel, alloy steel, and similar ferrous workpieces where a medium grit finish is acceptable. The vitrified bond provides rigidity and porosity suited to wet or dry surface grinding operations at controlled feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 flat wheel profile — standard fit for horizontal spindle surface grinders\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for rigid, consistent cutting action\u003c\/li\u003e\n  \u003cli\u003e80 grit, K hardness (medium grade) for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure promotes self-dressing and sustained sharpness\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction with grain structure designation 6\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 horizontal spindle surface grinders accepting an 8 inch diameter wheel with a 1-1\/4 inch arbor hole and 1\/4 inch face width.\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 B11.9 and applicable shop safety standards. Always inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Power down and lock out the grinder before installing or changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Perform a ring test and run the mounted wheel at operating speed for at least one minute in a guarded position before bringing it into contact with a workpiece.\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: 0.25 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\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: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Grade\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\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: 29A80K6V31\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: 66253255604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51730736546098,"sku":"66253255604","price":33.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90251c493f3221e6f367714fef920570.jpg?v=1788721956","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255604-surface-grinding-wheel-8in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
