This insert carries the DNMX 431-WF 4415 designation and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN to deliver wear resistance and thermal stability during continuous and interrupted cuts. The 55-degree diamond insert shape (Shape Code D) provides a sharp, defined cutting geometry. With a 0.40 mm corner radius, a 12.70 mm inscribed circle, and four available cutting edges, this insert is suited to high-productivity steel and cast iron turning applications. It is installed and indexed by licensed machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily applied in turning operations targeting steel workpieces (ISO material group P) and cast iron (ISO material group K). The WF chip breaker geometry supports controlled chip formation across a range of depths of cut and feed rates in both roughing and finishing passes. The neutral hand orientation makes it usable in standard right-hand toolholders configured for DNMX-style inserts. Typical installations include OD turning, facing, and light profiling on production lathes in job shops, manufacturing facilities, and maintenance shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eWF chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum indexing value\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method compatible with standard DNMX toolholders\u003c\/li\u003e\n  \u003cli\u003eISO code DNMX 15 04 04-WF 4415 for cross-reference and system compatibility verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting DNMX-style inserts with a clamp or screw holding method.

Use the correct torque wrench and seating tool specified by the toolholder manufacturer when securing the clamp or screw. Inspect the insert pocket and seating surfaces for chips or debris before seating a new edge.
