It uses an aluminum oxide abrasive grain bonded with a vitrified bond, producing consistent, repeatable cuts in high-production and toolroom environments. At 46 grit with a K hardness rating (medium), this wheel delivers a coarse cutting action suited for rapid material removal while maintaining workpiece integrity. The semi-friable grain structure continually exposes fresh cutting edges as the wheel wears, extending usable life under normal grinding conditions. Licensed machinists and grinding machine operators are the primary installers and users of this consumable.\u003c\/p\u003e\u003cp\u003eThis wheel fits surface grinders configured for a 7-inch diameter wheel with a 1-1\/4-inch arbor hole. The 1\/2-inch thickness is appropriate for straight surface grinding passes on flat workpieces. It is used in job shops, tool-and-die operations, and maintenance machining departments where consistent material removal from steel, cast iron, and similar hard metals is required. The non-porous, vitrified bond resists loading on dense ferrous materials and holds its form well under moderate to heavy grinding pressure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile for use on horizontal-spindle surface grinders\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with semi-friable grain for self-sharpening performance\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigidity and resistance to heat and coolant\u003c\/li\u003e\n\u003cli\u003e46 grit, K hardness (medium) for coarse, efficient stock removal\u003c\/li\u003e\n\u003cli\u003eGrain structure grade 6 for balanced porosity and wheel strength\u003c\/li\u003e\n\u003cli\u003ePink wheel color consistent with standard aluminum oxide identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders accepting a 7-inch diameter, 1\/2-inch wide, Type 1 wheel with a 1-1\/4-inch center hole and a maximum operating speed of 3600 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways power down and lockout\/tagout the grinder before mounting or removing a grinding wheel. Inspect the wheel for cracks or chips before installation and perform a ring test by tapping lightly with a non-metallic object to confirm it produces a clear tone. Mount with the correct flange size and never exceed the rated maximum speed of 3600 RPM. Grinding wheel installation and dressing should be performed by qualified personnel following ANSI B11.9 and applicable shop safety standards.\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\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.5 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\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\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\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\u003eMaximum Speed\u003c\/strong\u003e: 3600 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A46K6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: 66253255657\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":67989043511602,"sku":"66253255657","price":26.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19912372002376c80150593b516ee444.jpg?v=1792305956","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255657-surface-grinding-wheel-7in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
