VNMG 120402 T9225 — ISO turning insert for medium–heavy steel machining — Tungaloy

The VNMG120402E-PS T9225 is an ISO turning insert for external and internal turning, engineered for reliable performance in variable and slightly interrupted cuts.

• CVD-coated carbide grade T9225
• Robust universal grade for medium–heavy steel
• Rhombic VNMG form, 0° clearance angle
• 0.2 mm corner radius, cylindrical centre hole

Consistent cutting performance under variable loads

The CVD-coated T9225 grade combines a hard, wear-resistant surface with a tougher substrate, delivering a balanced performance suitable for medium–heavy steel machining. The CVD process deposits a thin, adherent coating that reduces flank wear and contributes to a longer tool life without sacrificing fracture resistance. Paired with the PS chipbreaker, the insert promotes controlled chip formation across varying depths of cut, which reduces unplanned stoppages and supports higher productivity in batch or single-piece production.

Precision seating and predictable repeatability for efficient setups

Compatibility with toolholders is governed by form, clearance, tolerance class, fastening method, size and thickness; the rhombic VNMG geometry and the cylindrical centre hole ensure stable clamping and exact positioning in standard ISO holders. The insert’s 4.76 mm thickness and 12 mm inscribed circle match common toolholder specifications, while the 0° clearance angle and 0.2 mm corner radius provide predictable tool engagement and surface generation. This reduces setup iterations, improves repeatability between tool changes and lowers the risk of incorrect seating.

Lower operating cost through process stability and surface quality

Using an indexable insert designed for robustness cuts downtime and overall cost per component: the universal character of the grade minimises tool inventory while supporting a wide tolerance of cutting conditions. The geometry and coating combination enhance wear resistance and edge stability, yielding consistent surface finish on turned parts and fewer in-process interventions. The VNMG120402E-PS T9225 insert therefore contributes to steady cycle times and reliable results in both external and internal turning operations, making it a practical choice for production environments that value uptime and predictable outputs.

FAQ

Which materials is this insert suited for?
The VNMG120402E-PS T9225 insert is designed primarily for medium–heavy steel machining and performs well where tougher cuts or slightly interrupted cuts require increased toughness.

What is the purpose of the PS chipbreaker?
The PS chipbreaker on this insert promotes controlled chip formation for reliable evacuation and reduced entanglement, supporting stable cutting in the recommended steel applications.

How does the 0.2 mm corner radius affect machining?
A 0.2 mm corner radius balances strength and surface finish: it strengthens the cutting edge against chipping while helping to achieve a consistent surface profile on turned components.

Which holder characteristics must match for correct use?
Correct compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic VNMG form and cylindrical centre hole are standard features for ISO-compatible holders.

Is the insert coated and how does that help?
Yes, the insert uses a CVD-coated carbide grade (T9225) which enhances wear resistance and edge life while maintaining sufficient toughness for variable cutting conditions.
