It features a multilayer CVD coating of TiCN and Al2O3, delivering wear resistance and thermal stability under demanding cut conditions. The insert measures 0.5 inches in length and 0.5 inches inscribed circle diameter, with a corner radius of 3\/64 inches (0.0469 inches) and a 3\/16-inch thickness. The RN chip breaker geometry and chamfered-and-honed cutting edge are suited for continuous and interrupted cuts on steel and cast iron workpieces. This insert is installed by machinists and CNC turning professionals in production environments.\u003c\/p\u003e\u003cp\u003eThis insert is designed for use in turning, facing, and boring operations on a lathe or turning center. It targets primary workpiece materials including steel (ISO P) and cast iron (ISO K). With eight cutting edges per insert and a neutral hand orientation, it is a versatile tooling choice for general-purpose external and internal turning on both manual and CNC equipment. The KENLOC series designation indicates compatibility with KENLOC-style insert holders using clamp and pin holding methods. The square insert shape and 90-degree included angle make it well suited for profiling and shoulder work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN plus Al2O3 for heat and wear resistance in steel and cast iron cuts\u003c\/li\u003e\n\u003cli\u003e8 usable cutting edges per insert for extended tool life and cost efficiency\u003c\/li\u003e\n\u003cli\u003eRN chip breaker with chamfered and honed edge for controlled chip formation and edge security\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation supports use in both right-hand and left-hand toolholders\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.1665 inches suitable for medium stock removal\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO code SNMG120412RN for global toolholder cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series insert holders that accept SNMG-style square inserts with clamp and pin holding.
