TNMG 160404 GH330 ISO triangular turning insert by Tungaloy — 0° rake, 60° included angle

The TNMG160404 GH330 is an ISO‑standard triangular indexable insert designed for external and internal turning applications, offering a balanced mix of wear resistance and edge stability for a wide range of workpiece materials.

GH330 wear grade for long tool life
Triangular ISO shape for versatile clamping
Double-sided chipbreaker for reliable chip control
0.4 mm corner radius for precise finishing

Increased process stability through a wear‑resistant grade

The GH330 grade, developed by Tungaloy, combines high wear resistance with controlled toughness to extend edge life under typical turning loads. Selecting an insert with this composition reduces the frequency of index changes and contributes to uninterrupted production cycles. The combination of a robust carbide substrate and the designated coating chemistry helps maintain cutting edge integrity during continuous turning operations, which directly supports higher uptime and lower tooling cost per part.

Precise geometry for repeatable clamping and surface quality

The triangular ISO form with a 60° included angle and a 0° relief angle ensures predictable engagement with standard external and internal holders. The insert’s 0.4 mm corner radius delivers a compromise between edge strength and the ability to achieve fine surface finishes, useful for medium‑tolerance components. Because compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness, the insert integrates with existing toolholders when those criteria are matched, enabling consistent part quality across batches.

Stable chip control and efficient material removal

Equipped with a double‑sided chipbreaker, the insert supports controlled chip formation for a variety of feeds and depths of cut, reducing the risk of chip entanglement and improving surface integrity. The central cylindrical hole facilitates secure clamping and straightforward indexing, while the two cutting edges per side maximise usable life before disposal. This design improves machining reliability and contributes to predictable cycle times, a key factor when optimising production throughput.

FAQ

What materials can this insert machine effectively?
The TNMG160404 GH330 insert is intended for turning a broad range of materials; the GH330 grade prioritises wear resistance while retaining sufficient toughness for many steels and alloyed materials.

How many usable cutting edges does the insert provide?
The triangular TNMG geometry offers three corners and, combined with the double‑sided design, provides multiple usable edges before replacement is necessary.

Is the insert compatible with standard ISO toolholders?
Compatibility depends on matching the insert form, relief angle, tolerance class, fixing method, size and thickness; the TNMG160404 conforms to ISO standards for straightforward integration when those parameters align.

What benefit does the 0.4 mm corner radius bring to component quality?
A 0.4 mm corner radius increases edge strength for interrupted cuts while still allowing improved surface finish compared with larger radii, making it suitable for medium‑tolerance finishing passes.

Does the chipbreaker support a range of feeds and depths of cut?
Yes, the double‑sided chipbreaker is designed to provide reliable chip formation across typical turning feeds and depths, assisting in process stability and surface integrity.
