It measures 4 inches in diameter, 1 inch thick, with a 1\/2-inch arbor hole. The 46-grit coarse grade makes it well suited for aggressive material removal, deburring, and rough surface prep where a finer finish is not required. Machinists, fabricators, and tool and die workers install this wheel on compatible bench grinders and surface grinding machines. The arbor hole size accommodates standard spindle configurations common in light industrial and shop environments.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is used in metalworking and fabrication shops for surface grinding operations on steel, cast iron, and similar workpiece materials. The coarse 46-grit rating removes material efficiently, making it appropriate for first-pass grinding, weld cleanup, and scale removal. It is a single-unit item with no minimum order quantity beyond one piece, suited for both shop stocking and individual job use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter fits bench grinders and small surface grinders with standard arbor setups\u003c\/li\u003e\n\u003cli\u003e1-inch wheel thickness provides stability and longer service life under moderate grinding loads\u003c\/li\u003e\n\u003cli\u003e1\/2-inch arbor hole accommodates common spindle sizes in light industrial applications\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade optimized for aggressive stock removal and rough surface preparation\u003c\/li\u003e\n\u003cli\u003eSold individually, allowing single-unit procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard consumable grinding wheel for bench grinders and surface grinding machines accepting a 4-inch diameter wheel with a 1\/2-inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation and dressing should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test. Never exceed the maximum RPM rating of the wheel or the machine spindle speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 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: 0.5 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CRATEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 80390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRATEX","offers":[{"title":"Default Title","offer_id":67911853637938,"sku":"80390","price":245.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f0a39a34c5030c6f69ab7a65785b7a9.jpg?v=1791221862","url":"https:\/\/voomisupply.com\/products\/cratex-80390-surface-grinding-wheel-46-grit-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
