Designed for precision metal removal on CNC lathes and turning centers, this insert features a 55-degree diamond (rhombic) shape, a 0.5000-inch inscribed circle, and a 0.0315-inch corner radius. The TS2500 grade targets superalloys and titanium as its primary workpiece materials while also performing in steel, stainless steel, and cast iron applications. With 4 cutting edges, a negative rake geometry, and an MF4 chip breaker optimized for finishing and medium machining, it delivers controlled chip flow and repeatable surface finishes. Licensed machinists and CNC operators in aerospace, energy, and general machining install this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, and back turning operations on CNC lathes and turning centers where consistent tool life across difficult-to-machine materials is required. The DNMG platform accepts clamp, pin, and lever-lock holding methods, giving it broad compatibility with standard DNMG-style toolholders. It is applicable across ISO material groups P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium). The MF4 chip breaker geometry supports light to medium depths of cut, making it well suited for finishing passes and semi-finish operations in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTS2500 carbide grade with multilayer PVD TiAlN and TiN coating for high wear resistance across ISO P, M, K, and S material groups\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (DNMG) with negative rake and negative side clearance for secure, stable seating\u003c\/li\u003e\n\u003cli\u003eMF4 chip breaker geometry optimized for finishing and medium machining operations\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholder systems\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut up to 0.5787 inches; insert length 1.2204 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for DNMG 432-MF4 style toolholders accepting inserts with ANSI code DNMG432 and ISO code DNMG150408.

Always index or replace inserts with the machine powered down and the spindle fully stopped. Use the correct torque wrench or clamp screw driver specified by the toolholder manufacturer to seat the insert without cracking the carbide substrate. Inspect the toolholder pocket and seating surfaces for chips or wear before loading a fresh insert to ensure proper contact and runout control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TS2500\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Medium Machining\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: 0.0315 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inches)\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: 0.5787 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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium (ISO S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S10, S20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02616001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557769871666,"sku":"02616001","price":329.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8827b05080c889b61be7f30f14b18743.jpg?v=1786394753","url":"https:\/\/voomisupply.com\/products\/seco-02616001-dnmg-432-mf4-ts2500-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
