CNMG120408 T9225 indexable turning insert — ISO CNMG 120408 for Turning, Tungaloy

The CNMG120408 T9225 insert is an ISO‑format, rhombic indexable cutting part designed for external and internal turning where robustness and versatility are required.

• CVD-coated carbide grade T9225 for robust use
• ISO CNMG 120408, 80° rhombic geometry
• 0.8 mm corner radius with double-sided chipbreaker
• Central hole, cylindrical fit; 4.76 mm plate thickness

Proven coating and substrate for secure tool life

The CVD‑coated carbide substrate of this insert, designated T9225, is formulated to deliver a balance of toughness and wear resistance that suits Stahl machining under varying engagement conditions. The CVD-coated surface reduces flank and crater wear by providing a thermal barrier and improved adhesion, which translates into reliable tool life and fewer index changes in batch production. For shops switching between heavy cuts and lightly interrupted depths, this composition helps maintain consistent performance and lowers overall tooling costs per component.

Geometry engineered for stable cutting and clamping

Thanks to the ISO CNMG 120408 rhombic form with an 80° included angle and 0.8 mm corner radius, the insert provides a versatile contact geometry that improves load distribution during turning. The 0° clearance angle helps achieve predictable engagement on facing and external profiles, while the standard plate thickness of 4.76 mm contributes to rigidity in the holder. The central cylindrical hole ensures predictable clamping and repeatability across compatible toolholders, so the cutting edge position remains stable even in interrupted cuts.

Chip control and indexing that save cycle time

A double-sided chipbreaker on the insert supports effective chip formation and evacuation across a range of feeds and depths, which reduces the risk of built-up edge and keeps surface finish consistent. Being indexable and reversible, the geometry offers multiple usable edges per insert, accelerating changeover and reducing machine downtime. The secure fit with compatible holders also mitigates vibration, improving dimensional accuracy and surface quality on consecutive parts.

Application focus: efficient medium-to-heavy turning

Designed primarily for medium to heavy Stahl work, the insert excels where tougher engagement and occasional interruptions demand toughness rather than ultra‑thin coatings. The ISO format and standard mounting make it straightforward to integrate into existing tool systems; selection of the correct chipbreaker and grade helps tailor the insert to batch size, material variability and machine rigidity. Backed by Tungaloy’s production standards, the part supports predictable output in demanding workshop environments.

FAQ

What machining tasks is this insert best suited for? The CNMG120408 T9225 insert is intended for medium‑to‑heavy turning of Stahl, including external and internal operations and applications with slightly interrupted cuts.

How does the T9225 grade affect performance? Tungaloy’s T9225 grade combines a tough substrate with a CVD coating to improve wear resistance and edge stability under varying engagement conditions, offering longer life on demanding turning tasks.

Is the insert compatible with common ISO CNMG holders? Compatibility depends on holder form, free clearance angle, tolerance class, fixation method, size and thickness; the insert conforms to the ISO CNMG 120408 form and mounts with a cylindrical central hole for standard clamping systems.

How does the chipbreaker design influence results? The double‑sided chipbreaker facilitates controlled chip formation and evacuation across a range of feeds, improving surface finish and reducing the likelihood of built‑up edge during longer cuts.

How many cutting edges are available per insert? The reversible CNMG geometry provides multiple indexable edges; the insert’s double‑sided format and secure clamping allow several repositions before replacement is required.
