Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a controlled finish. It measures 8 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. The 60-grit, I-hardness rating places it in the medium-grade range, making it suitable for general surface grinding work where moderate material removal and reasonable wheel life are both priorities. Maximum operating speed is rated at 3600 RPM. The wheel weighs approximately 1 pound.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is suited for surface grinders used in machine shops, tool-and-die operations, maintenance facilities, and industrial production environments. The Type 1 straight-wheel profile is the standard configuration for horizontal-spindle surface grinders. The aluminum oxide grain and vitrified bond combination performs well on carbon steel, tool steel, and similar hardened workpieces where consistent, repeatable results are required. The semi-friable grain structure supports self-sharpening behavior under load, helping maintain cut rate through the wheel's service life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight-wheel profile for horizontal-spindle surface grinders\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent stock removal\u003c\/li\u003e\n\u003cli\u003e60 grit, I hardness (medium grade) for general surface grinding on ferrous metals\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure promotes self-sharpening during use\u003c\/li\u003e\n\u003cli\u003eNon-porous, grain structure 6, specification 28A60I6V31\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type 1 replacement or substitute 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\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting and dressing should be performed by qualified machinists or grinding machine operators familiar with ANSI B11.9 safety standards for grinding machines. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the marked maximum RPM. Use the correct arbor flanges and blotters as required by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\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: White\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\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\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\u003eSpecification\u003c\/strong\u003e: 28A60I6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66253255434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51753030156594,"sku":"66253255434","price":46.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c069b7b3e1257364dea3dfd9be57a5f6.jpg?v=1788932260","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255434-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
