TNMG 160412 T9225 – ISO turning insert for medium-to-heavy steel, Tungaloy

The TNMG160412 T9225 is an ISO-standard triangular turning insert engineered for robust external and internal turning operations, offering a versatile solution where changing engagement conditions or slight interruptions demand increased toughness.

• CVD-coated carbide grade T9225
• Robust universal for medium–heavy steel
• ISO TNMG shape, 60° included angle
• 1.2 mm corner radius, double-sided chipbreaker

Consistent cutting performance under variable conditions

The combination of CVD-coated surface and carbide substrate in this grade T9225 delivers enhanced wear resistance and stable cutting-edge behaviour, which is particularly beneficial during interrupted cuts or fluctuating engagement. The result is predictable tool life and fewer unplanned indexings — a clear advantage for production environments that demand steady throughput and reduced handling. This benefit is reflected in lower downtime and a more consistent surface finish when machining medium-to-heavy steel.

Designed for straightforward system integration

As part of the ISO TNMG160412 series, the insert is compatible with standard external holders and boring bars when the holder matches the insert’s form, relief angle, tolerance class, fastening method, size and thickness. The modular system consists of the insert, an appropriate holder or bar, a clamping set/shim and replacement screws. The specified 0° relief angle and 4.76 mm thickness must be observed when selecting a mating toolholder to ensure correct seating and secure clamping, which in turn supports stable cutting and repeatable positioning.

Practical geometry and handling for productive turning

The triangular form and double-sided chipbreaker provide multiple indexable edges and effective chip control, helping to maintain process reliability across a range of turning tasks. The 1.2 mm corner radius balances edge strength and profile accuracy, making the insert suitable for both general turning and more demanding roughing operations where robust edge retention reduces vibration and improves surface integrity. Indexing is straightforward and economical thanks to the multi-edge design, supporting lower tooling costs per machined part.

FAQ

What holder characteristics must match the insert?
Compatibility requires matching the insert form, relief angle, tolerance class, fastening method, size and thickness; the TNMG160412 must be used with holders designed for its ISO geometry to ensure correct seating and clamping.

Which materials is this grade best suited for?
The T9225 grade on the TNMG160412 is engineered as a robust universal for medium-to-heavy steel machining and performs especially well when changing engagement or slightly interrupted cuts occur.

How many usable cutting edges are available per insert?
The triangular, double-sided design provides multiple indexable edges — each side can be indexed, giving several usable edges before the insert requires replacement.

What does the CVD coating provide in practice?
The CVD-coated finish on the carbide substrate increases thermal and abrasive wear resistance, improving edge life and consistency in typical turning cycles.

For which machining tasks is the 1.2 mm corner radius recommended?
A 1.2 mm corner radius offers a compromise between edge strength and profile control, making it suitable for general turning and roughing operations where robust edge retention and reduced vibration are priorities.
