The wheel measures 4 inches in diameter and 1-1\/2 inches thick, with a 1-1\/4 inch arbor hole for secure spindle mounting. Constructed from aluminum oxide abrasive grain with a vitrified bond, it delivers consistent cut rates and thermal stability under continuous use. The 46 grit coarse grade removes material aggressively, making it suited for rapid stock removal rather than fine finishing passes. Hardness grade K provides a medium-hard bond retention that releases grain efficiently on harder workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for surface grinding machines used in metalworking shops, maintenance facilities, and tool rooms. It is appropriate for grinding ferrous metals including carbon steel, alloy steel, and hardened tool steel. The Type 11 flared-cup profile fits vertical-spindle surface grinders and bench grinder setups where a recessed contact face is required. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers and operators of this wheel type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain suited for ferrous metal stock removal\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity control, and resistance to heat distortion\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade enables aggressive material removal rates\u003c\/li\u003e\n  \u003cli\u003eK hardness grade balances bond retention with grain release on harder workpieces\u003c\/li\u003e\n  \u003cli\u003eType 11 flared-cup wheel profile for vertical-spindle and recessed-face applications\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction for consistent performance across the wheel face\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard service wheel for surface grinders accepting a Type 11 wheel with a 4 inch diameter, 1-1\/2 inch width, and 1-1\/4 inch arbor hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWheel mounting and dressing should be performed by a qualified machinist or maintenance technician familiar with ANSI B11.9 grinding machine safety standards. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation by performing a ring test. Never exceed the maximum RPM rating marked on the wheel, and confirm the spindle arbor size matches the 1-1\/4 inch hole before seating the flanges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 11\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: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1-1\/2 inches\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\u003ePorous\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\u003eWeight\u003c\/strong\u003e: 18.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253269909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51729063215410,"sku":"66253269909","price":28.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac3b06717db0cb38ae8645663616455e.jpg?v=1788699447","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269909-surface-grinding-wheel-46-grit-type-11","provider":"Voomi Supply","version":"1.0","type":"link"}
