It uses an aluminum oxide abrasive grain bonded with a vitrified bond system, producing a consistent, open-cutting action suited to surface grinder applications. At 100 grit with an H hardness rating, this wheel falls in the fine grade range, making it well-suited for finishing passes where surface finish quality matters as much as material removal rate. The vitrified bond resists heat and coolant, which helps maintain wheel integrity during wet or dry grinding operations. Rated at a maximum of 3600 RPM, it is sized for use on standard surface grinders found in machine shops and toolrooms.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on horizontal-spindle surface grinders in toolroom, maintenance, and production grinding applications. The 7-inch diameter, 1\/4-inch thickness, and 1-1\/4-inch arbor hole fit common surface grinder spindle configurations. The pink aluminum oxide grain and semi-friable structure make it particularly effective when working with tool steels and hardened alloy steels where controlled stock removal and surface integrity are priorities. Machinists and tool grinders are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile for horizontal-spindle surface grinding\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain with vitrified bond for consistent cutting action\u003c\/li\u003e\n  \u003cli\u003e100 grit fine grade delivers smooth surface finish on ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eH hardness (soft) rating promotes self-sharpening behavior and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure rated at grain structure 6 for controlled breakdown under load\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders accepting a 7-inch diameter, 1\/4-inch thick, Type 1 wheel with a 1-1\/4-inch arbor hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting should be performed by qualified machinists or toolroom personnel following ANSI B7.1 safety standards. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the maximum rated speed of 3600 RPM. Ensure the spindle arbor and flanges are clean and free of debris before seating the wheel, and use proper blotter pads between the flanges and the wheel faces. Power down and lock out the machine before any wheel change.\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\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: 7 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 Code\u003c\/strong\u003e: 29A100H6V31\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: 66253255643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51755123114290,"sku":"66253255643","price":28.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/673534b7357e9f80763653f82700d5be.jpg?v=1788951362","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255643-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
