VNMG120404E‑TM AH8015 — ISO turning insert for turning applications by Tungaloy

A VNMG120404E‑TM AH8015 insert designed for external and internal turning, offering stable cutting edges and optimised chip control for heat‑resistant alloys.

• PVD‑coated AH8015 grade
• ISO‑standard rhombic insert, 35° principal angle
• TM chipbreaker for heat‑resistant alloys
• 0.4 mm corner radius for precise profiles

High‑performance grade for heat‑resistant alloys

The AH8015 grade is a PVD‑coated carbide developed as a balanced choice between wear resistance and edge stability. For machining difficult, heat‑resistant materials, this combination reduces flank wear while maintaining a reliable cutting edge, which translates into fewer insert changes and more predictable batch throughput. The PVD coating improves oxidation resistance at elevated temperatures, helping to sustain cutting performance during longer cycles.

Stable cutting geometry for consistent results

With the rhombic ISO form and a 35° principal angle, the insert provides a predictable contact pattern and good access to external and internal profiles. The TM chipbreaker is optimised for fragmenting chips in tougher alloys, reducing the risk of long, continuous swarf and enabling safer, cleaner machining. The 0.4 mm corner radius supports fine profile definition while retaining sufficient edge strength for interrupted cuts, resulting in improved surface finish and dimensional consistency.

Clear compatibility and straightforward set‑up

ISO‑standardisation means compatibility depends on matching form, relief angle, tolerance class, fastening and size — the insert fits typical VNMG holders and tooling systems when these parameters align. The rhombic plate with a cylindrical hole ensures simple clamping and positive locating; when combined with the correct external holder and backing shim, set‑up is quick and repeatable. Where uncertainty exists about holder match or tolerance class, refer to holder documentation or contact technical advisors for clarification.

Economic machining and application guidance

Choosing a balanced grade such as AH8015 brings operational economy: extended tool life in demanding alloys and less frequent index changes lower overall operating costs. The insert is suitable for a broad range of turning operations — from finishing to medium roughing — on heat‑resistant alloys. For best results, pair with stable fixturing, appropriate cutting data for the workpiece material and a coolant strategy that supports thermal control; these measures maximise the benefit of the insert’s wear‑resistant coating and edge stability.

FAQ

What materials is this insert intended for?
The VNMG120404E‑TM AH8015 is formulated primarily for machining heat‑resistant alloys; the PVD coating and carbide substrate provide a balanced resistance to wear and good edge stability on such materials.

Which chipbreaker is fitted and what is its benefit?
This insert uses a TM chipbreaker that promotes short, controllable chips when turning tougher alloys, improving swarf control and reducing the risk of entanglement.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius offers a compromise between profile accuracy and edge strength, enabling fine surface finishes while tolerating minor interruptions during cuts.

Is the geometry compatible with standard VNMG holders?
The insert follows ISO‑standard geometry; compatibility with a holder depends on matching form, clearance angle, tolerance class, fastening and size, so verify these parameters against the chosen external holder.

What advantages does the PVD coating provide in practice?
The PVD coating on the AH8015 grade improves oxidation resistance and wear behaviour at elevated temperatures, contributing to longer tool life and more consistent cutting performance in demanding turning tasks.
