Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent stock removal and a durable cutting structure. It measures 8 inches in diameter, 1 inch thick, and carries a 1-1\/4 inch arbor hole. The 46 grit, coarse grade designation makes it well suited for aggressive material removal on ferrous and hard materials. Rated to a maximum of 3600 RPM, this wheel is a standard workhorse for production and maintenance grinding applications where controlled cut rate and wheel longevity matter.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is designed for use on horizontal spindle surface grinders in both production and maintenance shop environments. The Type 1 straight-wheel profile is the most common format for surface grinder applications and fits a wide range of table-mount and reciprocating-surface grinder setups. The coarse 46-grit ceramic construction makes it appropriate for rapid stock removal passes before finishing operations. Machinists, tool and die makers, and maintenance technicians typically select this wheel for roughing passes on steel and other hard materials where removal rate takes priority over surface finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for aggressive, consistent cutting action and extended wheel life\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides a rigid, porous-free structure that holds form under sustained grinding pressure\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade optimized for high stock removal rates\u003c\/li\u003e\n\u003cli\u003eK hardness code (medium) balances wheel wear rate with cutting efficiency\u003c\/li\u003e\n\u003cli\u003eType 1 straight-wheel profile fits standard surface grinder spindle arbors\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 3600 RPM rated for safe use on compatible machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Type 1 straight surface grinding wheel for use on horizontal spindle surface grinders accepting an 8 inch diameter wheel with a 1-1\/4 inch arbor hole running at or below 3600 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and dressing of grinding wheels must be performed by a qualified machinist or grinding technician following ANSI B11.9 and applicable shop safety standards. Before mounting, inspect the wheel for cracks or chips using the ring test, and ensure the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Power down and lock out the surface grinder before removing the existing wheel, and use proper flanges and blotters during installation. Always dress the wheel with an appropriate dressing tool before the first grinding pass to true the face and open the grain structure.\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\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: K (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: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 183A46K6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66254427331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51728405004594,"sku":"66254427331","price":203.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b305f7c977347b4e2bc64f33ff09b157.jpg?v=1788690899","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66254427331-surface-grinding-wheel-8in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
