CNMG120408-NMT WSM20S — Rhombic 80° indexable turning insert for stainless steels by Walter Tools

A CNMG120408-NMT WSM20S indexable turning insert engineered for secure chip control and enhanced edge life when machining stainless steels and heat‑resistant superalloys.

• Tiger·tec Silver coating for increased wear resistance
• NMT chipbreaker for controlled chip formation
• Rhombic 80° geometry for versatile turning
• 0° negative rake with 0.8 mm corner radius

Consistent performance for demanding stainless steel applications

The combination of the Tiger·tec Silver coating and a coated carbide substrate delivers a significant improvement in wear resistance and thermal stability during prolonged cutting operations. This makes the insert particularly suitable for stainless steels, which tend to be tough and generate heat at the cutting zone. The coating reduces adhesion and edge build‑up, so the process runs with fewer interruptions and more consistent surface quality. In practical terms, shops benefit from longer tool life and steadier component tolerances.

Controlled chip formation reduces downtime and improves safety

Equipped with the NMT chipbreaker, the geometry is optimised to split and evacuate chips reliably during interrupted or continuous cuts in demanding materials. Effective chip control minimises manual intervention and the risk of hot, tangled swarf, increasing operational safety and throughput. For production environments this translates into fewer stoppages, easier automation integration and predictable cycle times.

Robust geometry for edge security and flexible setup options

The rhombic 80° shape combines accessibility for varied turning tasks with a 0.8 mm corner radius that balances edge strength and finish. The insert’s 0° (negative) rake angle enhances mechanical stability under heavy or unstable cutting conditions, supporting secure cutting edges when facing hard or work‑hardening surfaces. This geometry supports a wide range of turning strategies while preserving the cutting edge under higher loads.

Designed for industry workflows and quality assurance

Tolerance class M indicates consistent dimensional accuracy suitable for standard industrial tool holders, while the designation and series ensure traceability within Walter Tools’ portfolio. The insert’s suitability for the ISO groups M (stainless steels) and S (superalloys/titanium) means it can be selected confidently for components that require high reliability and repeatable results. Technical teams will value the predictable behaviour in both manual and CNC turning operations.

FAQ

What materials is this insert best suited for?
The CNMG120408-NMT WSM20S by Walter Tools is formulated for stainless steels (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), offering controlled chip formation and edge stability.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the insert reduces adhesion and wear, extending tool life and improving surface finish in demanding turning operations.

What does the NMT chipbreaker do?
The NMT chipbreaker geometry breaks and directs chips for safe evacuation, reducing downtime and facilitating automated or high‑volume turning processes.

Is the geometry compatible with standard toolholders?
Yes; the rhombic 80° form and tolerance class M align with common indexable insert holders used in industrial turning setups.
