CNMG 120408 T9225 turning insert by Tungaloy — CVD‑coated carbide, rhombic 80°

A CNMG120408 T9225 indexable turning insert engineered for mid‑to‑heavy steel turning, compatible with ISO‑standard holders and suitable for applications with intermittent cuts.

• ISO CNMG 120408 geometry, 80° rhombic
• CVD‑coated carbide grade T9225 for steels
• Double‑sided chipbreaker, economical indexing
• 0° clearance angle, with cylindrical mounting hole

Consistent cutting performance for demanding steel work

The combination of a CVD‑coated surface and the T9225 carbide composition provides a balance of wear resistance and toughness suited to steel turning under variable engagement conditions. This indexable insert is specified for mid‑to‑heavy machining where occasional interruptions in the cut occur; the coating reduces abrasive wear while the substrate supplies edge stability. The net effect is longer productive life per index and predictable tool behaviour, which supports planned cycle times and reduces unscheduled tool changes.

ISO compatibility and secure clamping for reproducible results

Designed to the ISO CNMG shape and size, the insert ensures interchangeability within ISO‑compliant tool families. The CNMG120408 geometry, combined with a 0° clearance angle, matches the relevant holder geometries so that radial and axial positioning remain consistent across re‑indexed edges. Compatibility is determined by form, clearance, tolerance class, fastening method, size and thickness; adopting the correct external holder or boring bar and an appropriate clamping set guarantees stable support and repeatable surface finish.

Improved process economy through chip control and indexing

A double‑sided chipbreaker offers two usable edges per side and aids controlled chip formation in medium to heavy steel turning. Reduced chip scatter and predictable breakage lower the risk of edge damage under interrupted cuts, while the economical indexing workflow cuts downtime. Selecting the matching chipbreaker and grade results in fewer tool changes and steadier cutting forces, which helps to maintain machine uptime and optimise overall production costs.

System recommendations and practical application notes

Use the insert as part of a complete system: ISO turning insert, matched external holder or boring bar, shim/clamp set and spare screws. The CVD‑coated carbide grade is a robust universal choice for a broad range of steels and for operations where toughness is required due to variable engagement. For best results, combine the insert with a holder that provides rigid support and correct rake/relief geometry; this maximises edge life and ensures consistent surface integrity. The insert’s hole with cylindrical style allows standard fastenings for secure mounting.

FAQ

What materials is this insert suited for?
The CNMG120408 T9225 indexable insert (Tungaloy, SKU 6780765‑Tungaloy) is optimised for mid‑to‑heavy machining of steels and for conditions requiring additional toughness, such as slightly interrupted cuts.

How does the T9225 grade affect tool life?
Tungaloy’s T9225 CVD‑coated carbide offers enhanced wear resistance while maintaining edge robustness, which typically extends usable life per index in steel turning applications.

Is the insert compatible with standard CNMG holders?
Yes — the CNMG120408 geometry conforms to ISO specifications; compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness with the chosen holder.

What advantage does the double‑sided chipbreaker provide?
The double‑sided chipbreaker provides controlled chip formation and two usable edges per side, improving process economy by reducing downtime for indexing and minimising the risk of edge damage.

Can this insert handle interrupted cuts?
The combination of a tough carbide substrate and CVD coating in grade T9225 makes the insert suitable for operations with light to moderate interruptions in the cut, where increased toughness is beneficial.
