Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and form retention across flat grinding applications. The wheel measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. At 80 grit with a medium (K) hardness and semi-friable grain structure, it balances aggressive material removal with controlled surface finish. Machinists and tool-and-die professionals use this wheel on surface grinders requiring a straight, flat profile.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding operations on horizontal and vertical spindle machines in production shops, tool rooms, and maintenance environments. The vitrified bond provides rigidity and open pore structure that resists loading when working steel, cast iron, and similar ferrous workpieces. The 80-grit medium-grade specification makes it appropriate for intermediate stock removal where a moderate surface finish is acceptable. It is sold individually and fits standard surface grinder arbors accepting a 1-1\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain structure for consistent self-sharpening action\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and open structure to resist loading on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e80 grit, medium grade (K hardness) for intermediate stock removal and moderate surface finish\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess — compatible with standard surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color consistent with aluminum oxide abrasive classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style Type 1 straight surface grinding wheel for horizontal and vertical spindle surface grinders accepting an 8 inch diameter, 1\/2 inch wide wheel with a 1-1\/4 inch arbor bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSurface grinding wheels must be mounted by qualified personnel following ANSI B11.22 and OSHA 29 CFR 1910.215 guarding requirements. Always perform a ring test before mounting to check for cracks, and inspect flanges and blotters for proper fit and condition. Power down and lock out the machine before changing wheels. Never exceed the 3600 RPM maximum speed marked for this wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\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: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\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\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\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: 28A80K6V31\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: 66253255472\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51734909845810,"sku":"66253255472","price":32.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce5531ea6a82b1b6bd77592bcfa62394.jpg?v=1788767985","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255472-surface-grinding-wheel-8in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
