It carries the KCU25 manufacturer grade and features a physical vapor deposition (PVD)-applied AlTiN coating for improved wear resistance and thermal stability at elevated cutting speeds. The insert style is NR with a cutting width of 0.1252 inches (3.18 mm) and a maximum depth of cut of 0.1500 inches (3.81 mm). A full corner radius of 0.0626 inches (1.59 mm) produces a smooth, radiused groove bottom. The double-end design extends useful tool life before replacement is required. This insert is part of the Top Notch series and is held in place by a clamp-style toolholder.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, undercutting, and parting applications on ferrous and non-ferrous workpieces in production turning environments. The KCU25 grade with AlTiN coating is appropriate for a range of steel, stainless, and cast iron applications where PVD-coated carbide performs reliably. The Top Notch series is a widely used platform in job shop and production machining settings. Installation is performed by a machinist or CNC toolroom technician. The insert seats into a compatible Top Notch series clamp-style toolholder sized for insert seat size 3.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied AlTiN coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCutting width of 0.1252 inches (3.18 mm) for precise groove sizing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.1500 inches (3.81 mm); rated range 0.1500 to 0.2000 inches (3.00 to 4.00 mm)\u003c\/li\u003e\n  \u003cli\u003eFull corner radius of 0.0626 inches (1.59 mm) for radiused groove bottoms\u003c\/li\u003e\n  \u003cli\u003eDouble-end insert geometry extends service intervals\u003c\/li\u003e\n  \u003cli\u003eClamp-type insert holding method for positive seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series clamp-style toolholders that accept insert seat size 3 and are configured for NR-style grooving inserts.
