CNMG 120404 AH6235 — Indexable turning insert (CNMG 120404 · Turning) by Tungaloy

The CNMG120404 AH6235 is a PVD-coated carbide indexable insert engineered for robust external and internal turning, especially suited to stainless steels and interrupted cuts.

• PVD-coated carbide for tough materials
• 80° rhombic profile for versatile turning
• 0.4 mm corner radius for consistent edge
• Double-sided chipbreaker, with cylindrical hole

Reliable cutting performance for challenging materials

The PVD-coated carbide grade AH6235 delivers a balance of toughness and wear resistance that reduces edge breakouts during interrupted cuts and when machining stainless steels. This results in fewer tool changes and improved cycle time, supporting a more economical production flow. The robust substrate and coating combination stabilises the cutting edge under fluctuating loads, translating into dependable performance across serial turning operations.

Proven fit and quick indexability minimise downtime

The ISO-form CNMG120404 geometry ensures compatibility with standard CNMG holders by matching form, clearance and thickness specifications; this facilitates fast insert changes and consistent clamping. The 80° rhombic shape with a 0° clearance angle and a cylindrical hole offers secure seating and straightforward indexing, while the double-sided chipbreaker provides two usable cutting edges per side to extend service life. These characteristics reduce tool inventory complexity and simplify process planning.

Process security and shop-floor efficiency through optimised chip control

The double-sided chipbreaker on a rhombic plate promotes controlled chip formation and evacuation, lowering the risk of edge damage and improving surface finish in both external and internal turning. A 0.4 mm corner radius supports repeatable edge strength without sacrificing profile accuracy. Combined with the PVD coating, these features contribute to stable cutting performance, predictable wear behaviour and overall cost-efficiency in medium- to high-duty turning applications.
