It carries the TP1501 grade designation with a Duratomic CVD coating process applying TiCN, Al2O3, and Cr layers for extended tool life in steel and cast iron applications. The insert features a 55-degree diamond shape, a 0.5 inch inscribed circle, and a 1\/64 inch (0.0157 inch) corner radius. Four cutting edges per insert and a chamfered and honed cutting edge style make this a cost-effective choice for high-production turning environments. The MF2 chip breaker geometry supports controlled chip formation during finishing and light roughing passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external turning, facing, boring, and back turning operations on steel and cast iron workpieces. The TP1501 grade targets primary workpiece material code P (steel, P10-P20) and secondary codes K (cast iron) and H (hard materials). It is installed in negative-rake toolholders that accept DNMG-style inserts with clamp, pin, or lever-lock holding methods. Typical applications include shaft turning, facing operations on CNC machining centers, and general-purpose lathe work in job shop and production environments. The ISO code for this insert is DNMG150404-MF2.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDuratomic CVD coating with TiCN, Al2O3, and Cr layers for wear resistance in steel and cast iron cutting\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (Shape Code D) with 4 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eMF2 chip breaker geometry optimized for finishing and light roughing with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for edge strength and surface finish consistency\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock DNMG toolholder systems\u003c\/li\u003e\n  \u003cli\u003eMulti-use application support: turning, facing, boring, and back turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in negative-rake DNMG-style toolholders accepting a 0.5 inch inscribed circle insert with a tolerance code M and clearance code N.
