It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel uses a silicon carbide abrasive bonded with a vitrified bond, rated at 120 grit for fine-grade stock removal and surface finishing. The hardness code is I, placing it in the medium hardness range. Rated to a maximum of 3600 RPM, this wheel suits surface grinders and cylindrical grinding operations. Machinists, tool-and-die technicians, and grinding specialists are the primary users.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for grinding 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Its silicon carbide construction makes it especially effective on non-ferrous metals and hard, brittle materials where aluminum oxide wheels would underperform. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The non-porous, non-tapered, no-recess design simplifies mounting and reduces setup time across standard spindle configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive for effective cutting on non-ferrous metals, stainless steel, and stone\u003c\/li\u003e\n\u003cli\u003eVitrified bond for consistent wheel integrity and free-cutting action under load\u003c\/li\u003e\n\u003cli\u003e120 grit fine grade for finish grinding and precision surface work\u003c\/li\u003e\n\u003cli\u003eHardness code I medium hardness for balanced wear rate and workpiece contact\u003c\/li\u003e\n\u003cli\u003eNon-porous, no-recess, non-tapered Type 1 profile for straightforward spindle mounting\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum rating suitable for standard surface and cylindrical grinder spindles\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.

Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before installation using the ring test; never mount a damaged wheel. Ensure the machine spindle RPM rating meets or exceeds 3600 RPM and that all flanges and blotters are properly seated before operating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\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\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 39C120-IVMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 39C Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.35 pounds\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: 66252941632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542991667506,"sku":"66252941632","price":111.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3a69b7bbc59d0efef62c0d6ee1eded0.jpg?v=1785913156","url":"https:\/\/voomisupply.com\/products\/norton-66252941632-surface-grinding-wheel-7in-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
