It measures 8 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole. The wheel is made from white aluminum oxide abrasive with a vitrified bond and carries an I hardness code, placing it in the soft-to-medium hardness range. Rated to 3600 RPM maximum, it is suited for controlled stock removal on ferrous metals and tool steel. Machinists, tool grinders, and surface grinding operators are the primary users of this wheel type.\u003c\/p\u003e\n\u003cp\u003eThis wheel fits standard surface grinders that accept 8-inch diameter Type 1 straight wheels with a 1-1\/4 inch arbor bore. The 80 grit designation and grain structure 6 make it appropriate for intermediate material removal where a balance of cut rate and surface finish is needed. The semi-friable aluminum oxide grain self-sharpens during use, making it a common choice for surface grinding of hardened tool steel, high-speed steel, and similar ferrous materials in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess for standard surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive grain — semi-friable for self-sharpening performance on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid structure and consistent wheel form retention\u003c\/li\u003e\n  \u003cli\u003e80 grit with grain structure 6 balances stock removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eI hardness code (soft range) reduces heat buildup on heat-sensitive workpieces\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction rated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for surface grinders accepting 8-inch diameter Type 1 straight wheels with a 1-1\/4 inch arbor hole and a maximum spindle speed of 3600 RPM or lower.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting and dressing should be performed by a qualified machine operator or toolroom technician following ANSI B7.1 safety standards. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the maximum RPM marked on the wheel. Dress the wheel with an appropriate diamond dresser after mounting to true the face before grinding operations begin.\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)\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\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\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\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\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: 6\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: Non-Porous\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: 23A80I6V31\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: 66253255814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51734546252082,"sku":"66253255814","price":42.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1272846b8c162a9eb7194e5bce04f19c.jpg?v=1788763443","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255814-surface-grinding-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
