Designated style NP3012K with grade KCU25 and a physical vapor deposition (PVD) AlTiN coating, this insert delivers a 4.83 mm cutting width and a maximum depth of cut of 5.08 mm. The positive rake geometry and K chip breaker promote efficient chip evacuation in a range of grooving applications. Machinists and CNC operators install this insert using a clamp-style holder compatible with the Top Notch tooling system.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving operations in both production and job-shop turning environments. The right-hand orientation and 45-degree lead angle make it appropriate for standard external groove profiles. The KCU25 carbide grade with AlTiN coating is commonly applied to steel, stainless steel, and similar materials where wear resistance and thermal stability are priorities. The Top Notch series is a well-established platform used across a broad range of turning centers requiring repeatable insert indexing and secure clamping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD AlTiN coating for extended tool life in demanding grooving cuts\u003c\/li\u003e\n  \u003cli\u003e4.83 mm cutting width with a maximum depth of cut range of 5.00 mm to 10.00 mm\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with K chip breaker for effective chip control\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation with 45-degree lead angle\u003c\/li\u003e\n  \u003cli\u003e0.34 mm corner radius for controlled groove profile\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders.
