TNMG160408 T9225 – Indexable turning insert, 60° triangle (Tungaloy)

The TNMG160408 T9225 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a CVD‑coated carbide grade for robust performance in medium to heavy steel machining.

• CVD‑coated T9225 universal grade
• ISO TNMG160408 triangular insert
• 0.8 mm corner radius for robust edge
• Double‑sided chipbreaker, with cylindrical hole

Consistent performance for medium to heavy steel turning

The insert is based on a CVD‑coated carbide grade that balances wear resistance and toughness. As a robust universal grade, it is formulated for medium to heavy steel machining where engagement conditions change or slightly interrupted cuts occur. The coated surface reduces flank wear and extends tool life under thermal stress, while the carbide core preserves edge stability for repeatable component accuracy.

Improved chip control and tooling reliability

A double‑sided chipbreaker combined with the triangular geometry and a 0.8 mm corner radius promotes predictable chip formation and evacuation during turning operations. This design reduces the risk of built‑up edge and minimises machining interruptions. The 60° insert angle provides a versatile cutting geometry for both profile and finishing passes, contributing to steady cycle times and consistent surface quality.

System compatibility and mounting guidance

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The ISO designation connects to a broad range of external holders and boring bars; the insert’s cylindrical hole enables secure clamping and fast, repeatable indexing. Workshops benefit from the standardised format that simplifies spare‑part management within indexable tooling systems.

Choosing grade and chipbreaker for the application

Select the T9225 grade and corresponding chipbreaker according to workpiece material, depth of cut and machine rigidity. The universal nature of the grade suits a wide material mix, but pairing the insert with an appropriate holder and stable setup will maximise productivity and tool life. When conditions demand higher wear resistance, consider alternative grades or adjusted parameters while retaining the ISO TNMG geometry for compatibility.

FAQ

Which materials are suitable for this insert?
The TNMG160408 T9225 insert is specified for medium to heavy steel machining; the T9225 grade provides toughness for varying engagement conditions.

Is the insert reversible and indexable?
Yes, the triangular, double‑sided design allows indexing to fresh cutting edges; the TNMG geometry supports multiple edge positions.

What does the CVD coating change in performance?
A CVD‑coated surface increases wear resistance and thermal stability on the cutting edge, extending effective tool life under typical turning conditions.

How is the insert secured in the toolholder?
The insert is supplied with a cylindrical hole for clamping; compatibility requires matching holder form, fastening method and tolerance class.

Can this insert be used for internal turning?
Yes, the ISO TNMG form and size make the insert suitable for both external and internal turning when paired with an appropriate boring bar or holder.
