Precision and productivity for modern turning operations

The TNMG160404 GH330 indexable insert combines cemented carbide substrate and a Tungaloy carbide grade engineered for prolonged performance. The GH330 composition optimises the trade‑off between hardness and toughness, reducing flank and crater wear under mixed cutting conditions. With a 0.4 mm corner radius and ISO‑defined TNMG geometry, the insert supports repeatable cutting engagement and predictable tool life, which lowers tool change frequency and contributes to steady cycle times. As a result, machining centres and lathes benefit from improved uptime and lower overall tooling cost per part.

Compatibility and handling for secure clamping

The triangular form with a cylindrical hole and central mounting ensures secure fixation in compatible holders; compatibility depends on form, relief angle, tolerance class, fastening and insert thickness. The insert’s 4.76 mm thickness and 16 mm inscribed circle match common ISO TNMG holders, while the 0° relief angle and 60° included angle define the contact geometry required for radial and axial support. Using a matching clamping system and the appropriate double‑sided chipbreaker allows both external and internal turning with consistent chip control and reduced vibration, leading to a superior surface finish and repeatable tolerances.

Material behaviour and application advantages

Manufactured from cemented carbide and specified for turning, the grade is suitable where a balance of wear resistance and edge stability is needed; the double‑sided chipbreaker on this insert aids reliable chip formation across a range of steels and alloyed materials. The ISO‑compliant design simplifies inventory management and ensures interchangeability across machines that accept TNMG inserts. When paired with a robust holder and the correct feed‑speed parameters, the insert contributes to predictable tool life and process stability, which supports continuous production and consistent component quality.

FAQ

What materials is this insert suitable for?
The TNMG160404 GH330 Tungaloy insert is specified for turning and is optimised for a broad range of steels and alloyed materials thanks to its GH330 grade, delivering a balance of wear resistance and edge stability.

How does the GH330 grade affect tool life?
GH330 is a Tungaloy carbide grade that increases wear resistance while maintaining edge toughness; in practice the grade supports longer cutting intervals and stable performance in intermittent and continuous turning.

Is the insert reversible and how many cutting edges are available?
This is a double‑sided triangular insert; the design provides multiple cutting edges per insert, enabling cost‑efficient use before replacement.
