TNMG160408 GH330 Tungaloy turning insert (ISO 160408, 60°)

A TNMG160408 GH330 triangular indexable insert for turning operations, designed to balance wear resistance and edge stability in ISO-standard tool systems

• ISO 160408 geometry for standard holders
• GH330 grade optimised for wear resistance
• Double-sided chipbreaker for versatile turning
• Triangular insert with 0° rake and 60° angle

Reliable cutting performance for productive turning

The GH330 grade, combined with a cemented carbide substrate, provides a consistent mix of wear resistance and edge stability that supports longer tool life and dependable component quality. In practice, this means fewer interruptions for insert changes and a lower overall tooling cost per part. The double-sided chipbreaker helps control chip form across varying cut depths, which promotes stable cutting forces and contributes to predictable cycle times on lathes and turning centres.

Accurate fit and assured compatibility with ISO toolholders

Designed to the ISO 160408 designation, the triangular geometry and central hole ensure straightforward clamping in compatible toolholders. Key interface characteristics — form, relief angle, tolerance class, fastening style, size and thickness — determine fit and performance. The insert’s 0° rake and 60° included angle deliver a neutral cutting approach that suits a wide range of turning set-ups, while the cylindrical central hole supports secure, repeatable mounting in both external holders and boring bars.

Process flexibility and surface quality with clear handling

The combination of a well-balanced grade and a double-sided chipbreaker offers process flexibility for external and internal turning. For moderate to heavy cuts where edge stability matters, the GH330 grade maintains a robust cutting edge; for fine finishing passes the insert geometry supports consistent surface finish. Selection of an appropriate chipbreaker and cutting parameters should be aligned with workpiece stability and machining strategy to achieve the best results with minimal rework.

System context, handling and application guidance

Typical system composition includes the ISO indexable insert, a matching external holder or boring bar, and the necessary shim/clamp set and fastening elements for secure mounting. The triangular shape with a corner radius of 0.8 mm provides accessible indexing of multiple cutting edges, improving utilisation. When specifying tooling, consider holder rigidity and recommended cutting data for carbide grades; for tailored advice on cutting parameters or holder compatibility, consult the technical team to match the insert’s properties to the machining task.

FAQ

What holders are compatible with this insert?
Compatibility is determined by ISO geometry; the TNMG160408 GH330 insert fits holders designed for the ISO 160408 designation and matching tolerance and clamping features.

How many usable cutting edges does this triangular insert provide?
The triangular geometry provides multiple indexing positions; the TNMG160408 GH330 insert can be rotated to present fresh edges, improving overall tool economy.

Is this insert suitable for both roughing and finishing?
Yes, the combination of the GH330 grade and the double-sided chipbreaker allows flexibility for roughing and finishing operations when cutting parameters are adjusted to the workpiece and machine rigidity.

What is the purpose of the double-sided chipbreaker?
The double-sided chipbreaker on this indexable plate controls chip formation across different cutting depths, supporting stable cutting forces and consistent surface quality.

Which material is the insert made from?
The insert is manufactured from cemented carbide, a hard, wear-resistant material chosen to deliver long tool life under typical turning conditions.
