Manufactured from solid carbide with a CVD-applied Duratomic coating system of TiCN, Al2O3, and Cr layers, this insert delivers thermal resistance and edge stability across a range of steel and stainless steel workpiece materials. The insert features a 0.5 inch inscribed circle, a 1\/64 inch (0.0157 inch) corner radius, and an 80-degree diamond shape with a negative rake geometry. Four usable cutting edges and the MF3 chip breaker profile make this a cost-efficient choice for medium-duty turning, facing, and boring operations.\u003c\/p\u003e\u003cp\u003eThis insert is rated for primary use on steel (ISO material code P, grades P20, P30, and P40) and secondary use on stainless steel (ISO code M). Typical applications include external and internal turning, shoulder facing, and boring on lathes and turning centers in both job-shop and production environments. The MF3 chip breaker is optimized for medium feed rates and provides reliable chip control in continuous-cut conditions. Licensed machinists, CNC programmers, and toolroom technicians will find this insert suitable for a broad range of component materials in these categories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic coating: TiCN, Al2O3, and Cr layers for heat resistance and wear life\u003c\/li\u003e\n\u003cli\u003eMF3 chip breaker with chamfered and honed cutting edge for controlled chip flow at medium feeds\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (code C) with negative rake and N clearance for secure clamping\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use geometry supports turning, facing, and boring from a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for CNMG-style toolholders that accept a 0.5 inch inscribed circle, 3\/16 inch thick diamond-80 insert with a 0.2028 inch hole diameter.

Power down and lock out the spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the toolholder style (clamp, pin, or lever lock) to ensure the insert seats fully against the pocket. Do not exceed the maximum depth of cut of 0.4921 inch without verifying machine rigidity and workholding stability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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-MF3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: CNMG120404-MF3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG431-MF3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4921 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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 (CVD Duratomic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP3501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P20, P30, P40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF3\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\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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)\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\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package (minimum order quantity: 10)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 03096303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560159445298,"sku":"03096303","price":255.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/daa3b15752a3e0e72516c4d5abc127a3.jpg?v=1786447797","url":"https:\/\/voomisupply.com\/products\/seco-03096303-cnmg431-mf3-tp3501-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
