CNMG 120404 T9225 — Turning insert (ISO CNMG) by Tungaloy

The CNMG120404 T9225 is an ISO‑standard turning insert designed for external and internal turning, offering a balance of toughness and wear resistance for medium‑to‑heavy steel machining.

• CVD‑coated carbide for wear resistance
• Robust universal grade T9225 for steel machining
• Rhombic CNMG form with 0.4 mm nose radius
• Double‑sided insert with cylindrical hole

Consistent cutting performance for demanding steel turning

The combination of the T9225 grade and a CVD‑coating delivers a balance of wear resistance and impact strength that is particularly valuable when cuts are slightly interrupted or cutting conditions change. The CVD method produces a uniform, adherent coating that acts as a thermal and chemical barrier, extending tool life and improving surface finish under variable loads. This technical setup reduces tool‑related downtime and supports predictable part quality, which is essential for stable production cycles.

Simple integration with ISO tool systems and reliable clamping

The CNMG120404 geometry follows ISO standards and is therefore compatible with a wide range of ISO holders; compatibility depends on form, 0° clearance, tolerance class, fixing, size and thickness. The rhombic plate form with a 0.4 mm nose radius and 4.76 mm plate thickness offers a versatile cutting edge for finishing and light roughing, while the cylindrical hole ensures secure clamping. Being double‑sided makes the insert economical: after indexing, the second cutting edge restores full performance, improving cost per part and inventory efficiency.

Practical application advice and process benefits

This indexable insert is geared to turning tasks on a broad range of steels where mid‑to‑heavy removal rates are required; choose the double‑sided chipbreaker and grade appropriate to the workpiece and machine rigidity. For less stable setups, the tougher T9225 grade helps prevent edge chipping; for highly stable, high‑speed conditions consider a different chipbreaker or family better suited to finishing. The ISO form and standard sizing also speed up tooling changes and reduce machine set‑up time, supporting higher overall productivity and repeatable part quality.

FAQ

Is this insert suitable for interrupted cuts and variable engagement?
The CNMG120404 T9225 insert from Tungaloy is a robust universal grade with CVD‑coating and increased toughness, making it well suited to slightly interrupted cuts and fluctuating engagement typical in many turning operations.

Which toolholders fit this insert?
Compatibility follows ISO CNMG standards; the insert fits holders that match the CNMG form, 0° clearance geometry, the plate thickness of 4.76 mm and the 12 mm size; clamping depends on the holder’s tolerance class and fixing method.

Can the insert be indexed and reused?
Yes — the insert is double‑sided, allowing indexing to a fresh cutting edge; the cylindrical hole supports secure clamping for repeatable repositioning.

What materials is this grade intended for?
The T9225 grade is engineered as a universal, robust grade for steel machining in medium‑to‑heavy applications; select the chipbreaker and cutting data according to workpiece alloy and machine stability for optimal results.
