The insert features a triangular shape with a 60-degree included angle, a 0.5-inch inscribed circle, and a 0.03125-inch corner radius. It is coated with TiAlN via a PVD process, which improves heat resistance and edge life when cutting ferrous and difficult-to-machine materials. With 6 available cutting edges and a negative rake geometry, this insert delivers consistent, predictable performance in production machining environments. It is installed and indexed by licensed machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning, facing, and boring applications on steel, stainless steel, superalloys, and titanium. The FP chip breaker geometry is suited for finishing and medium-pass operations where chip control and surface finish are critical. The KCU10 grade, part of the KENLOC series, is optimized for interrupted and continuous cuts in the P, M, and S workpiece material categories per ISO classification. It carries both ANSI and ISO standards compliance and is identified by ISO code TNMG220408FP. Typical applications include shaft turning, bore finishing, and face profiling on CNC lathes and turning centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating for elevated heat resistance and extended tool life in steel and superalloy cutting\u003c\/li\u003e\n  \u003cli\u003e6 usable cutting edges per insert for maximum cost efficiency\u003c\/li\u003e\n  \u003cli\u003eFP chip breaker geometry optimized for finishing and medium-pass cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle with honed cutting edge for strength and edge stability\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code TNMG220408FP\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMG-style toolholders from the KENLOC series that accept TNMG432 inserts with clamp or pin holding methods.
