Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a repeatable finish. It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The 46 grit, H hardness (soft grade) specification suits coarse-to-medium material removal where the wheel needs to release abrasive grains readily to prevent loading and heat buildup. The vitrified bond offers rigidity and porosity control suitable for wet or dry surface grinding applications. This wheel is rated to a maximum of 3105 RPM.\u003c\/p\u003e\n\u003cp\u003eIntended for use on surface grinders in machine shops, tool rooms, and maintenance environments. The 8-inch diameter fits a range of bench-style and reciprocating surface grinders. The semi-friable grain structure and H hardness make it well-suited for grinding softer to medium-hardness steels where a freer-cutting action is needed. Machinists, toolmakers, and maintenance technicians handling precision flat grinding or tool reconditioning are the primary installers and users of this wheel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile for standard surface grinding applications\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for rigid, consistent cutting action\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade suited for efficient stock removal\u003c\/li\u003e\n  \u003cli\u003eH hardness (soft rating) allows grain release to reduce heat and loading\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure with grain structure rating of 6\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction with no recess; white wheel color for easy inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Type 1 straight surface grinding wheel for use on surface grinders accepting an 8-inch diameter wheel with a 1-1\/4 inch arbor hole and a maximum spindle speed at or above 3105 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSurface grinding wheels must be installed and dressed by a qualified machinist or toolroom technician. Before mounting, inspect the wheel for cracks using a ring test and confirm the machine spindle speed does not exceed the wheel maximum RPM of 3105. Power down and lock out the grinder before mounting or removing the wheel. Use proper flanges and blotters as required by ANSI B7.1 safety standards for abrasive wheel machinery.\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\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\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\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\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eRecess Type\u003c\/strong\u003e: No Recess\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: 3105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A46H6V31\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: 66253255819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51734638592306,"sku":"66253255819","price":52.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddeb0c84c4dcd5256e3cadb03907aee6.jpg?v=1788764237","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255819-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
