Built from aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rate and long wheel life on ferrous metals and tool steels. The wheel measures 8 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole, a 3-1\/4 inch recess diameter on one side, and a maximum operating speed of 3,105 RPM. At 46 grit with H hardness code and a grain structure of 6, it falls in the coarse, soft range — well suited for aggressive material removal where surface finish is secondary to stock removal rate.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on horizontal-spindle surface grinders in machine shops, tool rooms, and industrial maintenance environments. The Type 5 recessed profile allows clearance for the spindle flange on compatible machines. The aluminum oxide grain and vitrified bond make it appropriate for grinding carbon steels, alloy steels, and similar ferrous workpiece materials. It is a single-wheel package, suitable for individual replacement or as a spare in production grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 one-side recessed profile with a 3-1\/4 inch recess diameter for spindle flange clearance\u003c\/li\u003e\n\u003cli\u003e46 grit coarse aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eH hardness (soft) rating allows the wheel to release dull grains and self-sharpen during use\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity, porosity control, and resistance to oils and coolants\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure balances sharpness retention with controlled breakdown\u003c\/li\u003e\n\u003cli\u003eRated to 3,105 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use wheel for horizontal-spindle surface grinders accepting a Type 5 wheel with an 8 inch diameter, 1 inch face width, and 1-1\/4 inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheels must be installed by a qualified machinist or grinding equipment operator following ANSI B11.9 and applicable shop safety standards. Always perform a ring test before mounting to check for cracks, and confirm the machine spindle speed does not exceed the 3,105 RPM maximum rating marked on the wheel. Power down and lock out the grinder before changing wheels. Never overtighten flange hardware — consult the machine manufacturer for proper clamping torque guidance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness 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: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A46H6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 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: 66253255498\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51732585546034,"sku":"66253255498","price":43.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/938071ce4af50f89fdcf503b5b1378a2.jpg?v=1788744686","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255498-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
