Built with a ceramic abrasive grain and vitrified bond, this wheel delivers consistent cutting action across a range of ferrous and non-ferrous workpieces. At 46 grit and K hardness, it falls in the coarse-grade, medium-hardness range — well suited for aggressive material removal while maintaining wheel integrity. The wheel measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and carries a maximum operating speed of 3600 RPM. Specification code 183A46K6V31 is stamped on the wheel for verification before mounting.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is intended for use on horizontal-spindle surface grinders in production and maintenance grinding applications. The 8-inch diameter and 1-1\/4 inch arbor hole suit standard benchtop and floor-standing surface grinder configurations commonly found in tool-and-die, fabrication, and general machine shop environments. The coarse 46-grit ceramic grain is appropriate for initial surface passes, rapid stock removal, and conditioning of rough stock before finishing operations. The vitrified bond provides good porosity control and fracture resistance under steady grinding loads. Wheel color is blue; grain structure is 6; recess type is none.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for consistent, cool-cutting performance across multiple passes\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction resists loading and maintains wheel shape under steady grinding pressure\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade suited for aggressive stock removal applications\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) balances wheel wear rate with workpiece surface integrity\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess for standard surface grinder spindle mounting\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum operating speed rated for safe use on appropriate equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for horizontal-spindle surface grinders accepting an 8-inch diameter, 1\/2-inch thick, Type 1 wheel with a 1-1\/4 inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be installed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Before mounting, perform a ring test to check for cracks and confirm the wheel speed rating meets or exceeds the grinder spindle speed. Always shut down and lock out the grinder before changing wheels, and use the correct flanges and blotters as specified by the machine manufacturer. Never exceed the maximum operating speed of 3600 RPM marked on the wheel.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 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: 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, No Recess)\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\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\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: 66253292309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51727380414770,"sku":"66253292309","price":59.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acbda9027bb6e7c0f74109d037b0e9e6.jpg?v=1788677020","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253292309-surface-grinding-wheel-46-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
