CNMG 120404 AH8015 turning insert — Tungaloy

The CNMG 120404 AH8015 is an ISO-standard turning insert developed for external and internal turning of heat‑resistant alloys with a balanced focus on wear resistance and cutting-edge stability

• ISO-standard rhombic geometry
• PVD-coated carbide grade AH8015
• Double-sided chipbreaker for versatility
• Compatibility with standard CNMG holders

High‑temperature performance with controlled flank wear

The insert is specified for turning heat‑resistant alloys where a controlled compromise between edge strength and wear resistance is required. The PVD-coated carbide substrate offers improved surface hardness and reduced adhesion at elevated temperatures, while the AH8015 grade balances wear resistance and cutting-edge stability to extend in‑process life. This combination supports consistent machining results and reduces unplanned tool changes during serial production.

Geometry and clamping for repeatable accuracy

Rhombic geometry with an 80° approach angle and a 0.4 mm corner radius provides a compromise between toughness and finish. A 0° clearance angle and a plate thickness of 4.76 mm ensure reliable seating and stiffness in standard CNMG holders. The insert's cylindrical hole facilitates secure clamping and repeatable indexing, which supports process stability and consistent part tolerances over multiple tool changes.

System compatibility and application guidance

As an ISO turning insert, compatibility with a holder depends on form, clearance angle, tolerance class, fastening, nominal size and thickness. The insert suits both external and internal turning; choosing an appropriate chipbreaker and grade for the workpiece material and machining stability is essential. For general turning of heat‑resistant alloys this grade is a first choice, while alternative chipbreakers or grades can be selected for interrupted cuts or softer materials.

Operational economy through indexed use and simple tooling

The double‑sided chipbreaker design allows the insert to be indexed to a fresh edge, improving usable edge count and lowering tooling costs per component. Combined with the AH8015 wear behaviour, the insert helps to maintain surface quality and reduce cycle interruptions. For process planners the predictable wear pattern translates into easier tool life forecasting and fewer emergency interventions on the shop floor.

FAQ

What materials is this insert intended for?
The CNMG 120404 AH8015 turning insert from Tungaloy is specified as a first choice for the general machining of heat‑resistant alloys and similar high‑temperature materials.

How does the AH8015 grade influence performance?
The AH8015 grade with a PVD coating combines wear resistance and edge stability to provide consistent tool life and reliable surface quality in demanding turning operations.

Which holder characteristics determine compatibility?
Compatibility is determined by the holder's form, clearance angle, tolerance class, fastening method, nominal size and plate thickness; the insert is ISO‑standard CNMG geometry for use with matching holders.

Is the insert indexable on both sides?
Yes, the insert features a double‑sided chipbreaker that permits indexing to a fresh cutting edge, extending the total usable edges before replacement.

What effect does the 0.4 mm corner radius have on cutting?
A 0.4 mm corner radius helps to balance edge strength and surface finish—providing better edge robustness than a small radius while maintaining acceptable surface quality.
