It features a multilayer CVD coating of TiCN, Al2O3, and TiOCN applied via MTCVD process, delivering wear resistance and thermal stability across a range of cutting conditions. The insert has a 1\/2 inch inscribed circle, a 0.508 inch length, a 3\/16 inch thickness, and a 1\/32 inch corner radius. With four cutting edges and a neutral hand orientation, this insert is suited for high-volume production environments where tool life and consistent surface finish are priorities.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning, facing, and boring operations on steel and cast iron workpieces, corresponding to ISO material groups P and K. The MW chip breaker geometry is optimized for medium-duty cutting passes where chip control and edge stability matter. It is held in place by clamp and pin methods, making it compatible with standard CNMG-style toolholders in the KENLOC series. Machinists and CNC operators in job shops, production facilities, and tool rooms are the primary installers of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiOCN for extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003eMW chip breaker geometry optimized for turning and facing on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for reduced cost per edge\u003c\/li\u003e\n\u003cli\u003eNegative rake angle with honed cutting edge for stable, predictable cuts\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits both right-hand and left-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method provides rigid insert seating during interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style toolholders within the KENLOC series.
