CNMG120408 T9215 indexable turning insert (ISO 120408) for turning — Tungaloy

A CNMG120408 T9215 indexable turning insert engineered for productive medium‑steel machining with CVD‑coated carbide and an 80° rhombic geometry.

• CVD‑coated carbide grade T9215 for wear resistance
• ISO 120408 rhombic 80° geometry for universal turning
• 0.8 mm corner radius for stable cutting performance
• Double‑sided insert with cylindrical hole for secure clamping

Consistent productivity through wear‑resistant coating

The CVD‑coated carbide in T9215 combines surface hardness with fracture resistance to extend tool life in medium‑steel applications. The coating reduces flank and crater wear, which translates into longer uninterrupted running times and fewer indexings. For manufacturers seeking reliable cycle times, this grade supports higher material removal rates without sacrificing edge integrity. The coating and carbide substrate together enable predictable tool change intervals, simplifying production planning.

Easy integration with ISO tool systems for efficient tooling management

Being an ISO 120408 rhombic insert, the component fits a wide range of standard external holders and boring bars when the holder matches form, clearance, tolerance class, fixation and thickness. The double‑sided design halves the cost per cutting edge versus single‑use tips, while the cylindrical hole ensures reproducible clamping and repeatable edge positioning during index changes. This compatibility reduces inventory complexity and speeds up tool replacement on the shop floor, making tooling logistics more efficient.

Stable cutting geometry for surface finish and process security

The 80° geometry and 0.8 mm corner radius deliver a balance between edge strength and surface finish: the rhombic shape supports robust engagement while enabling fine finishing passes when required. The specified 4.76 mm plate thickness contributes to rigidity at the cutting zone, which helps dampen vibration in less stable set‑ups and maintains dimensional accuracy. Where light interruptions occur, the combination of geometry and grade offers higher resistance to chipping, leading to fewer scrapped parts and more consistent results.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9215 insert is optimised for medium‑steel machining thanks to its CVD‑coated carbide grade T9215, providing good wear resistance and fracture toughness for continuous to lightly interrupted cuts.

How does the ISO 120408 designation affect holder choice?
ISO 120408 denotes the rhombic form and dimensions; a compatible external holder or boring bar must match the insert form, thickness (4.76 mm), fixation and tolerance class to ensure correct seating and secure clamping.

What economic advantages does the double‑sided design offer?
A double‑sided insert doubles the available cutting edges per part compared with single‑use tips, reducing the cost per edge and lowering inventory turnover for cutting tools.

Can the insert be used for interrupted cuts?
Yes, the T9215 grade balances wear resistance and fracture strength to handle light interruptions; however, severe interruptions should be evaluated with appropriate machining parameters and holder rigidity.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm radius improves edge strength for roughing while still allowing acceptable surface finishes; smaller radii tend to produce finer finishes but offer less edge robustness.
