It is constructed with aluminum oxide abrasive grain and a vitrified bond, producing a rigid wheel structure that holds its form throughout the cut. At 100 grit with a J hardness rating and a grain structure of 6, this wheel delivers fine material removal with consistent surface finish. The semi-friable abrasive sheds dull grains to expose fresh cutting edges, supporting cooler grinding action. It is rated to a maximum of 3600 RPM and is intended for use on surface grinding machines by skilled machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications in toolrooms, machine shops, and maintenance environments. The Type 1 straight-wheel profile mounts directly to surface grinders with a standard 1-1\/4 inch arbor bore. Its fine 100-grit specification makes it appropriate for finishing passes and close-tolerance work on steel, cast iron, and similar ferrous workpieces where surface quality and dimensional control are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight profile with no recess for direct mounting on surface grinders\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for rigid, consistent cutting action\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain continuously exposes fresh abrasive during grinding\u003c\/li\u003e\n\u003cli\u003e100 grit fine grade with J medium hardness for finish grinding applications\u003c\/li\u003e\n\u003cli\u003ePink wheel color indicates aluminum oxide composition suited to ferrous metals\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum for safe operation on compatible machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type 1 replacement surface grinding wheel for surface grinders equipped with a 1-1\/4 inch arbor bore and operating at or below 3600 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be installed and dressed by a qualified machinist following applicable ANSI B11 and OSHA abrasive wheel safety standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and perform a ring test per ANSI B7.1 guidelines. Never exceed the maximum RPM rating stamped on the wheel.\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\u003eDiameter\u003c\/strong\u003e: 7 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\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 (Fine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\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\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 Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A100J6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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: 66253255646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51738627146034,"sku":"66253255646","price":28.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/236e35d960a82205c605c4c216624100.jpg?v=1788802012","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255646-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
