It carries a Physical Vapor Deposition (PVD) AlTiN coating optimized for finishing operations on steel, stainless steel, and superalloys. The insert follows a triangular shape with a 60-degree included angle, a 7-degree relief angle, and a positive rake geometry at 15 degrees. The FP chip breaker is engineered for finishing cuts, delivering controlled chip formation at light depths of cut. With 3 usable cutting edges per insert and a screw-on holding method, this insert suits high-volume turning, facing, and boring operations where tool change efficiency matters.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for CNC lathe and turning center applications in industrial machining environments. It is well suited for finishing passes on steel and stainless steel workpieces where moderate wear resistance and toughness are required. The KCU25 grade also supports cast iron and aluminum and non-ferrous materials, as well as superalloys and titanium, making it a versatile option across multi-material production cells. Installation is performed by machinists and CNC tooling technicians using standard screw-on insert toolholders accepting TCMT-style inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating provides moderate wear resistance and toughness across steel, stainless steel, cast iron, aluminum, and superalloy workpiece materials\u003c\/li\u003e\n  \u003cli\u003eFP chip breaker geometry designed for finishing operations with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (15 degrees) and positive side clearance reduce cutting forces on finish cuts\u003c\/li\u003e\n  \u003cli\u003e3 cutting edges per insert extend tool life and reduce per-edge cost\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method for secure clamping and repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for improved edge stability on finishing passes\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards (ANSI: TCMT2151, ISO: TCMT110204)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on TCMT-style insert toolholders accepting a triangular insert with a 0.25-inch inscribed circle.
