It features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied via MTCVD process, delivering high toughness on steel and moderate wear resistance on stainless steel and superalloys. The insert measures 19.34 mm (0.7616 inches) in length with a 3\/4 inch inscribed circle and a 3\/64 inch (0.0469 inch) corner radius. The 80-degree diamond shape provides a strong cutting edge geometry suited to roughing and medium machining operations. Licensed HVAC technicians, machinists, and tool-room professionals working on CNC lathes and turning centers are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and superalloys including titanium-based workpiece materials. The UP chip breaker geometry is optimized for roughing and medium machining passes. The neutral hand orientation and negative rake angle make it compatible with standard KENLOC-style toolholders that accept CNMG 643 inserts. It is part of the KENLOC series and conforms to both ANSI and ISO standards, with ANSI code CNMG643 and ISO code CNMG190612.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCM25 grade with multilayer CVD coating: TiN, TiCN, and Al2O3 for toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake angle and honed cutting edge\u003c\/li\u003e\n  \u003cli\u003eUP chip breaker supports roughing and medium machining on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e4 usable cutting edges per insert with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI CNMG643 and ISO CNMG190612 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series and other standard CNMG 643 \/ CNMG190612 compatible toolholders that accept a 3\/4 inch inscribed circle insert with clamp or pin holding.
