It features a multilayer CVD coating of TiCN and Al2O3 that provides wear resistance and thermal protection during aggressive cuts. The insert has a 55-degree diamond shape, a neutral hand orientation, and a chamfered and honed cutting edge for consistent performance. With four usable cutting edges per insert, it delivers reliable tool life across a range of metal removal applications. This insert is installed and managed by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations on steel and cast iron workpieces. The KCP25C grade is positioned for general-purpose and semi-finish to rough turning on ferrous materials. It belongs to the KENLOC series and conforms to both ANSI and ISO standards, making it compatible with standard DNMG-style toolholders used in a wide range of machine tool setups. Its primary workpiece material codes are P and K, covering unalloyed to alloyed steels and gray to nodular cast irons.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP25C grade with multilayer CVD TiCN and Al2O3 coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with neutral hand and negative rake angle\u003c\/li\u003e\n\u003cli\u003eCorner radius of 3\/64 inches (0.0469 inches) for controlled surface finish\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool utilization\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style reduces chipping on entry\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for DNMG-style toolholders conforming to ANSI and ISO DNMG150412RN specifications.
