Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal with fine surface finish results. At 120 grit and H hardness, it falls in the soft-to-medium hardness range, making it well-suited for harder steels where the wheel needs to break down and expose fresh abrasive. The semi-friable grain structure supports controlled wear and extended wheel life under steady feed rates. Rated at a maximum of 3600 RPM, it is compatible with standard bench and surface grinders used in machine shops, tool rooms, and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for surface grinding applications where fine material removal and workpiece finish quality are the priority. The non-porous vitrified bond provides rigidity and form-holding ability, making it appropriate for precision grinding of flat surfaces. It is a standard choice for tool rooms, production grinding operations, and general-purpose machine shop use. Licensed machinists and tooling technicians typically install and dress this wheel as part of routine grinding setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile for surface and bench grinder use\u003c\/li\u003e\n\u003cli\u003e120 grit aluminum oxide abrasive for fine stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eVitrified bond with non-porous, semi-friable grain structure for consistent wheel breakdown\u003c\/li\u003e\n\u003cli\u003eH hardness (soft rating) suited for grinding harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eMaximum rated speed of 3600 RPM\u003c\/li\u003e\n\u003cli\u003eWhite wheel color consistent with standard aluminum oxide vitrified wheels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for surface grinders and bench grinders accepting a 7-inch diameter, 1\/4-inch thick Type 1 wheel with a 1-1\/4-inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation and mounting must be performed by a qualified machinist or trained technician following ANSI B11.9 and applicable OSHA standards for abrasive wheel machinery. Power down and lock out the grinder before removing or mounting any wheel. Always perform a ring test before mounting to check for cracks, and ensure the wheel guard is properly reinstalled before operating. Never exceed the rated maximum RPM of 3600.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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: 120\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\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A120H6V31\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: 66253269546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51749577031986,"sku":"66253269546","price":43.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e16db5532f5f5985643e2b7ce6015d2.jpg?v=1788907862","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269546-surface-grinding-wheel-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
