It features an 80-degree diamond insert shape, a 1\/2-inch inscribed circle, and a 0.0315-inch corner radius. The insert has a negative rake angle of 18 degrees, a chamfered and honed cutting edge, and four usable cutting edges per insert. The MF2 chip breaker geometry is engineered for medium-finish operations in steel and stainless steel applications. It is sized at 0.5079 inches in length and 0.1875 inches in thickness, and weighs approximately 0.02 pounds. Licensed machinists and CNC toolroom technicians are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for CNC turning, boring, and facing operations on steel (ISO material group P), stainless steel (M), and cast iron (K). It is particularly effective in medium-finishing passes where controlled chip formation and consistent surface finish are required. The TP25 grade and CVD multilayer coating provide wear resistance and thermal stability across a range of cutting speeds typical in production turning environments. The MF2 chip breaker geometry limits depth of cut to a maximum of 0.4756 inches, making it best suited for light to medium material removal rather than heavy roughing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG432-MF2 geometry with 80-degree diamond insert shape and negative rake for stable cutting\u003c\/li\u003e\n  \u003cli\u003eTP25 grade with multilayer CVD coating: TiCN, Al2O3, and Cr for extended tool life in steel\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum cost efficiency per unit\u003c\/li\u003e\n  \u003cli\u003eMF2 chip breaker optimized for medium-finish turning, boring, and facing\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eISO code CNMG120408-MF2 for cross-reference with ISO-standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNMG-series toolholders that accept a 1\/2-inch inscribed circle, 0.2028-inch hole diameter, and clamp, pin, or lever lock holding methods.

Power down and de-energize the machine spindle before seating or replacing inserts. Use the correct torque wrench and manufacturer-specified clamping hardware to secure the insert without overtightening, which can crack the carbide. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper insert orientation and cutting edge engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMG-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG432-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative (18 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P20, P30, P35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 10)\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03275997\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563404951858,"sku":"03275997","price":244.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85e18040aab2fc67cb5db8a658d73f47.jpg?v=1786496898","url":"https:\/\/voomisupply.com\/products\/seco-03275997-turning-insert-cnmg432-mf2-tp25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
