Built with a silicon carbide abrasive grain and a vitrified bond, it measures 6 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel carries an 80 grit, medium grade specification and is rated to a maximum of 4140 RPM. It weighs 0.75 pounds and features a non-porous, green-colored wheel body. Licensed tradespeople and skilled machinists typically reach for this wheel when they need consistent, controlled cutting action on hard-to-grind materials.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications in both production and tool-room environments. It handles a broad range of materials including 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Compatible equipment includes CNC cutting tool machines, cylindrical grinders, and surface grinders. Its medium grade and vitrified bond make it a practical choice when both cut rate and workpiece finish quality matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive grain — effective on hard, brittle, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent grain exposure throughout the wheel life\u003c\/li\u003e\n\u003cli\u003e80 grit, medium grade balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRated to 4140 RPM maximum for safe use on standard surface and cylindrical grinders\u003c\/li\u003e\n\u003cli\u003eNon-porous, Type 1 flat wheel geometry — no recess, no taper, straightforward mounting\u003c\/li\u003e\n\u003cli\u003eSeries 39C specification (39C80-IVMT) for traceability and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Before mounting, inspect the wheel for cracks or chips using a ring test — do not install a damaged wheel. Ensure the machine spindle speed does not exceed the 4140 RPM maximum rating stamped on the wheel. Power down and lock out the machine before changing wheels, and allow the wheel to reach full operating speed before bringing it into contact with the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/2 inch\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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\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\u003eMaximum RPM\u003c\/strong\u003e: 4140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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\u003eSeries Specification\u003c\/strong\u003e: 39C80-IVMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66252836816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541811560754,"sku":"66252836816","price":108.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27f5ebb2a73f5901e9d7bc07ef967149.jpg?v=1785885591","url":"https:\/\/voomisupply.com\/products\/norton-66252836816-surface-grinding-wheel-6in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
