VNMG120408E-TF 120408 T9215 — ISO turning insert, CVD-coated carbide, TF chipbreaker (Tungaloy)

A VNMG120408E-TF T9215 ISO insert engineered for external and internal turning applications in medium-duty steel machining.

• ISO-standard rhombic insert VNMG form
• CVD-coated carbide grade T9215
• TF chipbreaker optimised for steels
• 0° relief angle, 35° lead angle

Consistent productivity through advanced grade and coating

The VNMG120408E‑TF T9215 benefits from a CVD-coated surface and a robust carbide substrate, which together deliver high wear resistance under continuous and lightly interrupted cuts. The selected grade T9215 balances toughness and hardness to reduce the risk of edge breakage while enabling higher cutting speeds than uncoated grades. As a result, machining cycles become more productive with fewer insert changes, supporting stable batch processing and predictable tool-life management.

Precise geometry for secure seating and repeatable accuracy

Manufactured to ISO-standard dimensions in a rhombic VNMG form, the insert measures 12 mm across the cutting edge and has a plate thickness of 4.76 mm, with a corner radius of 0.8 mm for controlled chip formation. The part features a cylindrical hole for positive clamping and a 0° relief angle combined with a 35° lead angle, ensuring repeatable seating and consistent cutting forces. These measurable characteristics simplify holder selection and reduce set-up variation in serial production.

Machining behaviour and system-level recommendations

The integrated TF chipbreaker is tuned for medium steel applications and promotes short, manageable chips for safer high-productivity turning. The insert is suitable for both external and internal turning and performs best in continuous to lightly interrupted cuts when paired with a stiff toolholder and correct feed rates. The full working system comprises the insert together with a compatible external holder or boring bar, a correct underlay/clamping set and replacement screws to guarantee stable clamping and maximised tool-life.

FAQ

What materials is this insert best suited for?
The Tungaloy VNMG120408E‑TF T9215 insert is primarily specified for medium steel machining; the CVD-coated T9215 grade provides a good balance of wear resistance and toughness for continuous to lightly interrupted cuts.

Which dimensions and angles are critical for holder selection?
Key dimensions are 12 mm size, 4.76 mm thickness and 0.8 mm corner radius, with a 0° relief angle and a 35° lead angle; matching these values ensures correct seating and repeatable performance with compatible holders.

How does the TF chipbreaker influence machining?
The TF chipbreaker produces short, controllable chips in steel machining, improving chip evacuation and surface finish while supporting higher productivity in stable set-ups.

What components are required to build a working system?
A complete system uses the insert together with a matching external holder or boring bar, an underlay/clamping set and the correct replacement screws to secure the insert and ensure stable cutting.
