Manufactured from carbide grade KC5010 with a PVD-applied TiAlN coating, this right-hand insert delivers a 4.8 mm (0.189 inch) cutting width and a maximum depth of cut of 3.81 mm (0.150 inch). The neutral rake geometry and 0.57 mm corner radius suit a range of workpiece materials and groove profiles. Machinists and CNC operators use this insert in production environments where consistent groove width and tool life are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external grooving and cutoff applications in both high-volume production and job-shop turning. The Top Notch insert style (NG, size 3189) fits compatible Top Notch toolholders. The TiAlN coating provides thermal resistance at elevated cutting speeds, making it appropriate for ferrous and non-ferrous materials graded C3 and C4. A right-hand cutting orientation means it advances from right to left relative to the workpiece. The 55-degree included angle and 3-degree lead angle are typical of standard Top Notch grooving geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate, grade KC5010, with PVD TiAlN coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4.8 mm (0.189 inch) cutting width for consistent, repeatable groove sizing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 3.81 mm (0.150 inch); effective range 3.00 mm to 4.00 mm\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation, neutral rake, 0.57 mm corner radius\u003c\/li\u003e\n  \u003cli\u003eTop Notch series NG insert style, size 3189, for use with compatible Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eMaterial grade C3 and C4 coverage for broad workpiece material compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NG-style inserts, size 3189.
