WNMG080404-NMS WSM30S turning indexable insert – for stainless steels & superalloys | Walter Tools

The WNMG080404-NMS WSM30S is a trigon 80° turning insert engineered for robust performance when machining stainless steels and heat-resistant superalloys in demanding industrial turning applications.

• Tiger·tec Silver coated carbide grade WSM30S
• Trigon 80° shape for stable roughing
• 0.4 mm corner radius for robust edge life
• Negative 0° rake with NMS chipbreaker

Reliable cutting for tough materials and consistent productivity

The WSM30S grade, built on Tiger·tec Silver coating technology, is optimised for materials that challenge conventional tooling, notably stainless steels and high-temperature alloys. Its coated carbide composition improves thermal resistance and supports stable cutting edge behaviour, which reduces the risk of built-up edge and unexpected tool failure. For production environments where reproducible component quality is mandatory, this insert contributes to consistent cycle times and reduced rework by maintaining surface integrity and dimensional stability across batches.

Secure chip control and protected cutting edge for longer tool life

Thanks to the NMS chipbreaker geometry and negative 0° rake, the insert delivers controlled chip formation even under elevated cutting temperatures typical of superalloy machining. The 0.4 mm corner radius increases edge robustness, which helps absorb intermittent cutting forces and extends usable life before reconditioning. Controlled chip evacuation reduces tool–workpiece interaction issues and supports safer, cleaner machining bays; the combined geometry and grade therefore improve both process reliability and operator convenience.

Integration into production with straightforward handling and repeatability

The trigon 80° format provides strong seat support in standard tool holders and is suitable for a range of turning operations from roughing to semi-finishing, depending on cutting data and machine capability. The insert coding and form factor follow established industry conventions, allowing seamless replacement in existing tool systems and straightforward inventory management. Where process tuning is required, Metav Werkzeuge can advise on cutting parameters to balance material removal rate and tool life, helping to shorten ramp-up time on new components.
