CPMT 09T304 T9225 — ISO indexable turning insert, Tungaloy

The CPMT 09T304 T9225 is an ISO‑standard indexable insert for turning, designed for medium to heavy steel machining with a single‑sided chipbreaker and an 11° relief angle

• CVD‑coated carbide T9225 for wear resistance
• Robust universal grade for interrupted cuts
• ISO‑standard rhombic shape for easy replacement
• 0.4 mm corner radius for balance of strength and finish

Higher throughput through a robust universal grade

The CVD‑coated T9225 grade combines wear resistance with increased toughness, making it ideal for medium to heavy steel machining. This balance reduces tool changes and unplanned stoppages, which improves overall productivity. The coating resists abrasive wear while the substrate maintains edge strength under variable cutting conditions, so the result is stable chip formation and fewer rejects — a direct contribution to lower unit costs and more predictable production cycles.

Easy integration thanks to ISO conformity and clear compatibility criteria

Compatibility is governed by form, 11° relief angle, tolerance class, fixing method, size and thickness; matching these parameters ensures secure clamping and repeatable performance. The insert is an ISO‑standard rhombic type with a central hole (cylindrical hole plus single‑side countersink 40°–60°), so it is compatible with many common external holders and boring bars. When setting up, include the appropriate shim or clamp set and replacement screws to achieve the designed clamping force and repeatability.

Practical chip control and application guidance

The single‑sided chipbreaker is tuned for general turning operations and offers reliable chip control across a range of feeds and depths. With a 0.4 mm corner radius, the geometry provides a compromise between edge strength and surface finish: suitable for semi‑finishing and robust enough for moderately interrupted cuts. Select cutting parameters and a matching chipbreaker style according to workpiece hardness and the chosen feed to preserve insert life and achieve consistent surface quality.

Predictable performance and process security in daily use

Using an insert from a recognised tooling family supports process security and repeatable results in series production. The CVD coating and carbide substrate are engineered for consistent wear behaviour, which simplifies tool life planning and reduces variance in part quality. This contributes to a calmer shop floor and greater confidence in achieving required tolerances, especially in mixed‑batch environments where cutting conditions can vary.

FAQ

What applications suit this insert best?
The CPMT 09T304 T9225 insert is designed primarily for turning operations on steel where medium to heavy cuts or slightly interrupted conditions occur, delivering robust performance and reliable chip control.

How does the T9225 grade affect tool life?
The CVD‑coated T9225 grade improves abrasive wear resistance while preserving edge toughness, which extends tool life during demanding steel machining and reduces the frequency of insert changes.

Which holders are compatible with this ISO insert?
Compatibility depends on matching form, relief angle, tolerance class, fixing method, size and thickness; when these match, the insert fits standard ISO‑compliant external holders or boring bars.

Is the insert suitable for interrupted cuts?
Yes — the robust universal grade and geometry provide extra toughness for mildly interrupted cuts, making it appropriate for varied engagement conditions.

What role does the 0.4 mm corner radius play?
The 0.4 mm corner radius offers a balance between edge strength and surface finish: it strengthens the cutting edge for heavier engagement while still enabling acceptable surface quality for semi‑finishing operations.
