CNMG 120408 T9225 — Indexable turning insert for turning (Tungaloy)

The CNMG120408 T9225 is an ISO-format, rhombic indexable insert designed for external and internal turning, offering a robust universal grade for medium-to-heavy Stahl machining.

• CVD-coated carbide grade T9225
• ISO CNMG120408 rhombic 80° insert
• 0.8 mm corner radius for tough cuts
• Double-sided chipbreaker, with cylindrical hole

Reliable performance for medium-to-heavy Stahl turning

The CVD-coated carbide T9225 grade delivers a balance of wear resistance and toughness, making the insert suitable where interrupted cuts or variable engagement demand durability. The CVD (chemical vapour deposition) layer improves surface hardness and thermal stability while the carbide substrate preserves fracture resistance; this combination reduces flank wear and extends in-process life. Specified in the ISO CNMG120408 format, the insert aligns with common toolholder geometries, ensuring reproducible cutting conditions and steady component quality during longer production runs.

Predictable chip control and secure clamping reduce downtime

Built with a double-sided chipbreaker and a cylindrical hole, the geometry promotes consistent chip formation and reliable seat positioning in the cutter body. Predictable chips lower the risk of entanglement and protect surface finish, while the cylindrical hole supports secure clamping and repeatable indexing. These features together contribute to higher process security, fewer unscheduled interruptions and a more consistent cycle time in series production.

Straightforward integration into ISO tool systems for faster setup

Designed for standardised tool systems, the insert’s rhombic form and 80° cutting angle simplify selection of compatible holders. Key dimensions such as 4.76 mm thickness, 12 mm inscribed circle, 0° clearance angle and 0.8 mm corner radius should be checked against the chosen seat and fastening method to ensure optimal engagement. The double-sided design allows rotation to a fresh edge when required, reducing inventory needs and improving cost efficiency per cutting edge without sacrificing stability.

FAQ

Which materials is this insert intended for? The CNMG120408 T9225 insert (SKU TUN6780833) is engineered primarily for medium-to-heavy Stahl machining; the T9225 grade provides the toughness and wear resistance needed for variable engagement and interrupted cuts.

What advantages does the T9225 grade provide? T9225 is a CVD-coated carbide grade that combines surface hardness from the coating with a resilient carbide core, delivering improved wear resistance and enhanced toughness for demanding turning operations.

Is the insert indexable and how is it secured in the holder? The insert features an indexable, double-sided design and is secured via a cylindrical hole; this enables reliable clamping and rotation to a fresh cutting edge when reconditioning is required.

Which dimensions are critical for holder compatibility? Check the 12 mm inscribed circle, 4.76 mm thickness, 0.8 mm corner radius and 0° free clearance angle against the chosen holder seat and fastening system to ensure correct fit and cutting geometry.

Can this insert handle interrupted cuts or variable engagement? Yes, the combination of a tough carbide substrate and the CVD coating in the T9225 grade is suited to interrupted cuts and changing engagement conditions typical of medium-to-heavy Stahl turning.
