Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent stock removal and a controlled cut on demanding materials including stainless steel, tool steels, titanium, super alloys, and cast iron. It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. The I hardness code and medium grade rating make it suitable for moderate-pressure surface grinding applications where wheel life and cut consistency matter.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and tool-room environments. It is well suited to shops running 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, and iron castings including ductile and gray iron. The porous, semi-friable ceramic structure helps the wheel stay free-cutting under heat-sensitive grinding conditions, making it a practical choice for ferrous and exotic alloy work where thermal damage to the workpiece is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for consistent, free-cutting performance\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile, no recess, no taper\u003c\/li\u003e\n  \u003cli\u003e60 grit, medium grade (Hardness Code I) for balanced stock removal and finish\u003c\/li\u003e\n  \u003cli\u003ePorous, semi-friable structure reduces heat buildup during grinding\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with 400 series stainless, tool steels, titanium, super alloys, and iron castings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always perform a ring test before mounting and verify the spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Power down and lock out the grinder before changing wheels. Never use a wheel that shows cracks, chips, or damage from handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.09 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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253043652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542939697458,"sku":"66253043652","price":223.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1de1214092fded6ace72a11d8b5617ea.jpg?v=1785911699","url":"https:\/\/voomisupply.com\/products\/norton-66253043652-surface-grinding-wheel-8-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
