It carries the DNMP431-MF1 industry standard designation and is finished with a multilayer PVD TiAlN and TiN coating over a CP200 carbide substrate. The insert features a 55-degree diamond shape, a 0.5000-inch inscribed circle, and a corner radius of 0.0157 inches (1\/64 inch). With four available cutting edges and a negative rake geometry, this insert delivers consistent performance in demanding finish and semi-finish turning contexts. It is installed by machinists and CNC tooling professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for stainless steel, superalloys, and titanium (ISO material codes M and S), with secondary suitability for steel and cast iron (ISO codes P and K). Material grades M01, M10, M20, S10, and S20 are listed as supported. The MF1 chip breaker geometry supports finish to medium turning applications. Typical uses include back turning, boring, facing, and turning operations. The maximum depth of cut reaches 0.5945 inches, making it versatile across light finishing passes and moderate stock-removal cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCP200 solid carbide substrate with multilayer PVD TiAlN and TiN coating for wear resistance in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (shape code D) with negative rake for stable edge engagement\u003c\/li\u003e\n  \u003cli\u003eMF1 chip breaker optimized for finish and medium turning on stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces micro-chipping on hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code equivalent DNMG150404-MF1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard insert for DNMP-style toolholders that accept a 431 insert size with a 0.2028-inch hole diameter and clamp, pin, or lever-lock retention.

Use the appropriate torque wrench and insert key specified by the toolholder manufacturer for clamp, pin, or lever-lock retention systems. Inspect the insert pocket and seating surface for debris or wear before seating a new insert. Do not exceed the maximum depth of cut rating or use damaged inserts, as this can cause tool failure or workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNMP431-MF1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404-MF1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 55 (Shape Code D)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CP200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and TiN (Multilayer PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.2204 inches\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: 0.5945 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: Stainless Steel, Superalloys and Titanium (ISO M, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron (ISO P, K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M01, M10, M20, S10, S20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 00072240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558269681970,"sku":"00072240","price":313.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e752881dffafe1c7bbb1e722577f1c75.jpg?v=1786407974","url":"https:\/\/voomisupply.com\/products\/seco-00072240-turning-insert-dnmp431-mf1-cp200-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
