The wheel measures 8 inches in diameter by 3\/4 inches thick with a 1-inch arbor hole. It is made from aluminum oxide abrasive bonded in a vitrified bond system, producing a consistent, controlled cut. At 60 grit with a medium grade and an O hardness rating, it suits a wide range of ferrous metal grinding tasks including sharpening lathe tools, drill bits, and hand tools. Licensed machinists, maintenance technicians, and toolroom professionals are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis wheel is used in toolroom, maintenance shop, and production grinding applications where a general-purpose aluminum oxide wheel is appropriate. The vitrified bond and semi-friable grain structure make it well suited for grinding high-speed steel, carbon steel, and similar ferrous materials. The gray aluminum oxide formulation with a grain structure rating of 6 and non-porous construction supports steady stock removal without loading under normal shop conditions. It fits standard 8-inch bench grinders and pedestal grinders with a 1-inch arbor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch diameter Type 1 straight wheel fits standard bench and pedestal grinders\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade for general-purpose stock removal and tool sharpening\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled cutting action\u003c\/li\u003e\n\u003cli\u003eO hardness rating and semi-friable grain structure balance wheel life with cut rate\u003c\/li\u003e\n\u003cli\u003eNon-porous construction resists loading during ferrous metal grinding\u003c\/li\u003e\n\u003cli\u003eSpecification code 27A60O6V13 for cross-reference and replacement identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 8-inch bench and pedestal grinder applications requiring a 1-inch arbor hole and Type 1 straight wheel geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation and dressing should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Before mounting, power down and lock out the grinder completely. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the 3600 RPM maximum speed rating stamped on the wheel. Always install the supplied paper blotters between the wheel and flanges and use a properly fitted arbor bushing if the machine spindle diameter is smaller than 1 inch.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness\u003c\/strong\u003e: O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\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\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 27A60O6V13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.99 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: 66253255220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51748725063986,"sku":"66253255220","price":52.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6b01e9e2d7047dfddc18293dda44d50.jpg?v=1788897349","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255220-grinding-wheel-8in-60-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
