The wheel measures 8 inches in diameter and 1 inch thick with a 1-1\/4 inch arbor hole. It uses a silicon carbide abrasive bonded in a vitrified matrix, which provides consistent cutting action and good form retention during surface grinding operations. At 80 grit and I hardness, this wheel falls in the medium grade range, making it appropriate for moderate material removal where surface finish and dimensional accuracy both matter.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is well-suited for shop and production environments handling non-ferrous metals, cast iron, and hard non-metallic materials. The green silicon carbide compound is particularly effective on titanium and 300 series stainless steel, where friability and sharp cutting edges help prevent loading. It carries the 39C80-IVMT specification designation, identifying the abrasive type, grit, hardness, and bond system in standard Norton nomenclature.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive with vitrified bond for consistent cutting and good wheel life\u003c\/li\u003e\n\u003cli\u003e80 grit, medium grade (I hardness) for balanced stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, no taper\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eNon-porous structure; green wheel color for quick visual identification\u003c\/li\u003e\n\u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and de-energize the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per manufacturer guidelines. Never exceed the rated maximum speed of 3600 RPM.\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: 1 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\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: 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: 3600\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\u003eSpecification\u003c\/strong\u003e: 39C80-IVMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.75 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: 66253044425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544074649906,"sku":"66253044425","price":208.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a03140d388837eb7c3f68104d3648245.jpg?v=1785923714","url":"https:\/\/voomisupply.com\/products\/norton-66253044425-surface-grinding-wheel-8in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
