Carrying the KCU25 manufacturer grade with a PVD-applied AlTiN coating, this insert delivers thermal resistance and edge stability during interrupted cuts and high-speed turning. The right-hand NRD insert style provides a 1.58 mm cutting width and a maximum depth of cut of 3.18 mm, with a full-radius corner geometry measuring 0.79 mm. Installed via a clamp-style holder, it is a go-to choice for machinists and toolroom professionals running metric-dimensioned grooving applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external grooving, O-ring groove cutting, and profiling on ferrous and non-ferrous workpieces in production and job-shop environments. The AlTiN coating supports dry or near-dry machining conditions, making it appropriate for shops looking to reduce coolant use on compatible materials. The KCU25 grade is positioned for applications requiring a balance of toughness and wear resistance. At 0.025 pounds, the insert is lightweight and conforms to standard Top Notch clamp-style toolholders that accept the NRD3031 insert size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 carbide grade with PVD-applied AlTiN coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1.58 mm cutting width with a maximum depth of cut of 3.18 mm\u003c\/li\u003e\n  \u003cli\u003eFull radius corner geometry at 0.79 mm for clean groove profiles\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation, NRD insert style, insert size 3031\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle; metric measurement standard\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 accepting the NRD3031 insert size.

Power down and lock out the machine spindle before seating or removing the insert. Ensure the clamp and toolholder pocket are clean and free of chips before inserting to prevent seating errors that can cause premature edge failure.
