CNMG120408 T9225 ISO turning insert (rhombic, 80°) – Tungaloy

CNMG120408 T9225 is an ISO‑standard indexable insert for turning operations, designed for external and internal turning in varied steel applications.

• CVD‑coated carbide T9225 for robust cutting
• Universal grade for medium to heavy steel machining
• Rhombic CNMG geometry with 80° cutting angle
• Cylindrical hole, 4.76 mm plate thickness

Proven grade for interrupted and heavy cuts

The CVD‑coated T9225 composition is a robust, universal carbide grade developed for the challenges of medium to heavy steel machining. Its combination of wear resistance and reinforced toughness reduces flank wear under varying engagement conditions and during light interruptions, which results in longer effective tool life and fewer insert changes. In practice, this means more stable cycle times and predictable consumption for batch and single‑piece production.

Geometry tailored for consistent component quality

The CNMG rhombic form with an 80° cutting angle and 0° relief delivers a stable cutting line and favours straight turning passes and profiling where repeatable geometry is essential. The 0.8 mm corner radius supports edge strength while maintaining surface finish quality, and ISO‑standard dimensions guarantee that the insert seats correctly in compatible holders. Correct geometry selection assists in meeting tight tolerances and consistent part quality across shifts.

Practical benefits during setup and machining

The insert’s double-sided chipbreaker and cylindrical hole support reliable clamping and bidirectional use, thereby reducing tooling costs per effective cutting edge. A plate thickness of 4.76 mm provides robust support under heavier radial depths of cut and improves stability when paired with a suitable external holder or boring bar. Together, these features help to reduce downtime for index changes and simplify inventory management for production shops.

Selection and compatibility guidance for secure assembly

Compatibility is determined by the insert form, compatibility with holder seatings, tolerance class, mounting method, size and thickness; check these parameters against the machine‑side holder before fitting. Where workpiece material or rigidity varies, select a chipbreaker and the T9225 grade that match the required balance of cutting edge life and toughness. The insert is supplied as part of the ISO system comprising the indexable plate, matching external holder or boring bar, shim or clamp set and replacement screws for straightforward integration.

FAQ

How does the T9225 grade perform with interrupted cuts?
The T9225 grade is designed for increased toughness; the CNMG120408 T9225 insert resists chipping during light interruptions and variable engagement, offering stable life in interrupted cutting conditions.

Is this insert suitable for finishing passes on alloyed steels?
Yes. The CNMG120408 T9225 combines wear resistance and toughness, making it appropriate for medium‑to‑finish turning on alloyed steels when paired with an appropriate feed and speed.

Can the insert be used on internal turning applications?
Yes. The rhombic geometry and ISO‑standard dimensions allow use in both external and internal turning holders compatible with CNMG indexable plates.

What determines whether the insert fits a specific holder?
Fit is determined by the insert form, relief angle, tolerance class, mounting method, size and thickness; verify these against the holder specifications before assembly.
