It features a multilayer TiCN and Al2O3 CVD coating applied via MTCVD process, delivering a balance of wear resistance and toughness suited to demanding metal-removal operations. The insert is 12.9 mm (0.508 inches) long with a 0.5-inch inscribed circle, a 0.0313-inch corner radius, and an 80-degree diamond (rhombic) shape. With four cutting edges and a negative rake geometry, it is designed for roughing and medium machining passes. Licensed machinists and CNC operators working in production turning environments are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium workpieces. The KCM15B grade provides moderate wear resistance and toughness on steel (P-class) and moderate to high wear resistance on stainless steel (M-class), making it a practical choice across general-purpose and interrupted-cut scenarios in industrial machining cells. It is held by clamp or pin methods and seats in KENLOC-series toolholders accepting CNMG432 inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake angle for strength and stability\u003c\/li\u003e\n  \u003cli\u003eKCM15B grade with multilayer TiCN and Al2O3 CVD coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges, maximizing cost-per-edge efficiency\u003c\/li\u003e\n  \u003cli\u003eChip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin insert-holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI (CNMG432) and ISO (CNMG120408) insert standards\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for controlled entry and reduced chipping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG432 (ANSI) or CNMG120408 (ISO) inserts.
