CNMG120408-NRS WSM30S turning indexable insert by Walter Tools — Tiger·tec Silver, for stainless steels and superalloys

CNMG120408-NRS WSM30S is a robust turning insert designed for demanding turning operations in stainless steels and heat‑resistant superalloys, offering optimised chip control and high edge stability

• Tiger·tec Silver coated carbide grade
• NRS chip breaker for reliable chip control
• Suitable for stainless steels and superalloys
• Rhombic 80° with 0° negative rake

Reliable performance in tough materials

The combination of the Tiger·tec Silver coating and a tailored coated carbide substrate delivers high thermal resistance and reduced flank wear under elevated cutting temperatures. This results in a longer effective edge life when machining stainless steels and superalloys, where heat accumulation and material toughness typically shorten tool life. The specification therefore supports continuous production runs with fewer tool changes and predictable process windows.

Better chip control and surface quality

The integrated NRS chip breaker has been developed to produce consistent chip forms across varying feeds and depths of cut, reducing the risk of entanglement and machine downtime. Improved chip evacuation lowers heat concentration at the cutting zone and contributes directly to a better surface finish, so fewer secondary operations are required and cycle times are reduced. The clear link between chip geometry and finished part quality supports more efficient shopfloor workflows.

Geometry tuned for stable turning and heavy cuts

The rhombic 80° insert shape combined with a 0° negative rake offers increased cutting edge strength for interrupted cuts and heavier machining conditions. The 0.8 mm corner radius helps distribute cutting forces over a larger edge area, which mitigates notch wear and enhances dimensional stability of turned components. These geometric choices enable reliable performance in production turning where robustness and repeatable results are priorities.

Application focus and production benefit

Designed as part of Walter Tools’ Tiger‑tec Silver line, this insert is particularly suited to components made from stainless steels (ISO group M) and heat‑resistant superalloys or titanium (ISO group S). By selecting the CNMG120408‑NRS WSM30S, manufacturers gain a balance of wear resistance and chip management that supports higher process reliability and shorter non‑productive times, contributing to improved overall equipment effectiveness.

FAQ

What materials is this insert suitable for? The CNMG120408-NRS WSM30S turning insert from Walter Tools is designed for stainless steels (ISO group M) and heat‑resistant superalloys or titanium (ISO group S) and performs well where high temperatures and material toughness are present.

How does the NRS chip breaker improve production? The NRS chip breaker on this insert produces repeatable chip forms, improving chip evacuation and reducing downtime; this leads to more consistent surface quality and fewer interruptions in the machining process.

What are the key geometry benefits of this insert? The rhombic 80° shape with a 0° negative rake and 0.8 mm corner radius increases edge strength for interrupted or heavy cuts and helps maintain dimensional accuracy over longer tool life.

Which series and grade is this insert part of? This insert is part of the Tiger·tec Silver series and uses the WSM30S grade, a coated carbide designed for thermal stability and wear resistance in demanding materials.

Is the CNMG120408-NRS available for standard toolholders? The CNMG120408‑NRS format follows conventional CNMG geometry and is compatible with holders specified for CNMG inserts; toolholder selection should match the intended depth of cut and stability requirements.
