Manufactured from white aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent, free-cutting action across ferrous metals and tool steels. It measures 8 inches in diameter by 1\/2 inch thick with a 1-1\/4 inch arbor hole. The 46-grit coarse grade and J hardness rating make it well-suited for aggressive material removal while maintaining a controllable cut. The vitrified bond structure allows for efficient coolant penetration and self-dressing action during use. Rated to 3600 RPM maximum operating speed.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for horizontal or vertical spindle surface grinders commonly found in machine shops, tool-and-die operations, and maintenance facilities. It is suited for grinding flat workpieces, re-sharpening tool blanks, and cleaning up weld faces on ferrous materials. The coarse 46-grit specification targets applications where stock removal rate is the priority rather than surface finish. A licensed machinist or skilled grinding operator typically selects this wheel for roughing passes before moving to a finer grit for finish work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive grain for free-cutting action on ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity for coolant flow\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade suited for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eJ hardness rating with grain structure 6 for medium wheel hardness\u003c\/li\u003e\n\u003cli\u003eSemi-friable abrasive for controlled self-sharpening during grinding\u003c\/li\u003e\n\u003cli\u003eNo-recess Type 1 straight wheel profile for standard surface grinder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type 1 straight grinding wheel for surface grinders accepting an 8 inch diameter wheel with a 1-1\/4 inch arbor hole and a maximum operating speed of 3600 RPM or higher.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM stamped on the wheel. Use proper flanges and a blotter on each side of the wheel to ensure even clamping pressure.\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: 8 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: 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\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\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\u003eRecess Type\u003c\/strong\u003e: No Recess\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: 28A46J6V31\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: 66253255462\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51755822350642,"sku":"66253255462","price":36.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53d4915ae8b63386c2bea1bdf631a5e4.jpg?v=1788960108","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255462-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
