SNMG 120408 T9215 ISO turning insert for turning – Tungaloy

The SNMG 120408 T9215 is an ISO‑standard indexable turning insert for external and internal turning, engineered for efficient medium‑steel machining with a CVD‑coated carbide grade for high wear resistance.

• CVD‑coated carbide grade T9215
• 0.8 mm corner radius for sturdy edges
• Double‑sided, square plate, 4.76 mm thick
• Compatible with ISO 120408 turning holders

High productivity through robust cutting performance

The combination of a CVD‑coated surface and the T9215 carbide grade delivers enhanced wear resistance and reliable edge stability in medium‑steel applications. This composition reduces flank wear and increases tool life, which translates into fewer indexings and longer uninterrupted production runs. Designed for continuous to slightly interrupted cuts, the insert supports stable machining parameters that favour higher material removal rates and consistent surface finish without compromising component tolerances.

ISO conformity and simple tool‑chain integration

Presented in the ISO format SNMG 120408, the insert fits established square plate holders when matched by form, clearance angle, tolerance class, fastening and thickness. The double‑sided geometry and the cylindrical hole enable positive clamping and straightforward reversal of the cutting edge, while the 4.76 mm plate thickness ensures rigidity during heavier cuts. Where set‑up time and repeatability matter, this standardised design reduces downtime and simplifies tool inventory management across toolrooms and production lines.

Predictable cutting behaviour and application guidance

With a 0.8 mm corner radius, the insert provides a balanced compromise between edge strength and surface integrity, making it suitable for a broad range of turning operations on steel. The integrated chipbreaker design supports controlled chip formation, which improves evacuations and protects the workpiece and toolholder from irregular chip flow. For best results, pair the insert with a holder matched to ISO 120408 dimensions and select a chipbreaker and feed strategy that reflect the part geometry and cutting conditions. If uncertainty remains about optimal combinations, technical advice is available to match the insert to the workpiece and process demands.

FAQ

What materials is this insert suitable for?
The SNMG 120408 T9215 insert is specified for medium‑steel machining; the CVD‑coated T9215 grade balances wear resistance and toughness for productive turning of steel components.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge strength and reduces chipping risk; when using the SNMG 120408 for heavier passes, this radius helps maintain surface quality and extend edge life.

Is the insert reversible and how is it clamped?
The SNMG 120408 is double‑sided and features a cylindrical hole for positive clamping; the geometry allows indexation of multiple cutting edges and secure fixation in compatible ISO holders.

Which chipbreaker should be selected for interrupted cuts?
For slightly interrupted cuts, choose a chipbreaker suited to medium‑steel operations and the intended feed range; the SNMG 120408 supports stable chip formation when paired with a matching chipbreaker style.

What must be considered when matching a holder to this insert?
Compatibility depends on form, clearance angle, tolerance class, fastening type, size and thickness; ensure the holder matches ISO 120408 dimensions and provides the correct support and rigidity for the intended cutting conditions.
