Built with aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and free-cutting action across a wide range of surface grinding applications. It measures 8 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. The 80 grit, H hardness (soft grade) specification makes it well suited for medium-finish work where controlled material removal is the priority. Rated to 3600 RPM maximum operating speed, the wheel meets standard surface grinder spindle requirements for this diameter class.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on horizontal-spindle surface grinders in tool rooms, maintenance shops, and production environments. The aluminum oxide grain and vitrified bond combination performs reliably on tool steels, carbon steels, and similar materials. The semi-friable grain structure allows the wheel to self-dress to a degree, maintaining a sharp cutting face during extended use. Machinists, tool grinders, and maintenance technicians are the typical installers and users of this wheel type. It is suited for applications requiring a medium-grade finish with consistent dimensional results pass to pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile — compatible with standard horizontal-spindle surface grinder flanges\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for stable, consistent cut rates\u003c\/li\u003e\n  \u003cli\u003e80 grit, H hardness (soft grade) — suited for medium-finish surface grinding of ferrous metals\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure supports self-dressing action during use\u003c\/li\u003e\n  \u003cli\u003eNon-porous, grain structure 6 — delivers predictable wheel life and finish quality\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum speed rating for 8-inch diameter surface grinder applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount replacement or standard Type 1 grinding wheel for horizontal-spindle surface grinders accepting an 8-inch diameter wheel with a 1-1\/4 inch arbor hole and 1\/2 inch face width.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and wheel changes must be performed by a qualified machinist or toolroom technician following ANSI B7.1 safety guidelines for abrasive wheels. Always de-energize and lock out the grinder before removing or mounting a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test — a cracked wheel must never be used. Do not exceed the 3600 RPM maximum operating speed marked on the wheel, and always dress the wheel with an appropriate diamond dresser before the first grinding pass.\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 (Straight)\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\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Soft\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\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\u003eWheel Color\u003c\/strong\u003e: White\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\u003eSpecification Code\u003c\/strong\u003e: 23A80H6V31\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: 66253255832\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51747679338802,"sku":"66253255832","price":49.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82151ff77bfac0550a5d32bb12eee6a1.jpg?v=1788884429","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255832-surface-grinding-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
