The wheel measures 8 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole. It is made from aluminum oxide abrasive with a vitrified bond, rated at H hardness and a coarse 46 grit. The specification code 28A46H6V31 confirms the abrasive type, grit, hardness, and bond. Rated to a maximum of 3,105 RPM, this wheel suits moderate material removal passes on ferrous metals and tool steels. Installation and dressing are handled by machinists or grinding technicians.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for flat surface grinding applications on horizontal-spindle reciprocating-table surface grinders. The coarse 46 grit and H hardness rating make it appropriate for aggressive stock removal rather than finish grinding. The vitrified bond provides rigidity and consistent cutting action across the wheel face. The non-porous, semi-friable aluminum oxide grain structure with a grain structure rating of 6 supports controlled breakdown and self-sharpening behavior during use, which is beneficial when working with harder ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile — standard fit for horizontal-spindle surface grinders\u003c\/li\u003e\n\u003cli\u003e46 grit coarse aluminum oxide abrasive for efficient stock removal\u003c\/li\u003e\n\u003cli\u003eH hardness (soft rating) with semi-friable grain for consistent self-sharpening\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigidity and stable cutting geometry\u003c\/li\u003e\n\u003cli\u003eSpecification code 28A46H6V31 for precise cross-referencing\u003c\/li\u003e\n\u003cli\u003eNon-porous construction and no recess — straightforward mounting and dressing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on horizontal-spindle reciprocating-table surface grinders accepting an 8 inch diameter, 1\/2 inch wide Type 1 wheel with a 1-1\/4 inch arbor bore running at or below 3,105 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be installed by a qualified machinist or grinding technician following ANSI B11.23 and the grinder manufacturer's guidelines. Always ring-test the wheel for cracks before mounting, and never exceed the rated maximum RPM of 3,105. Power down and lock out the grinder before changing wheels, and dress the wheel with an appropriate diamond dresser before the first cut. Always use the machine guard in place during operation.\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: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46 (Coarse)\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\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\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\u003ePorosity\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: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A46H6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\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: 66253255459\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51744867975474,"sku":"66253255459","price":44.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e7d1a5de4319f57db10f6e33f60d6a0.jpg?v=1788861731","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255459-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
