SNMG120408-NRS WSM20S – Turning indexable insert, Tiger·tec Silver, for stainless steels and superalloys | Walter Tools

The SNMG120408-NRS WSM20S is a square 90° turning indexable insert engineered for productive machining of stainless steels and heat‑resistant superalloys, combining a coated carbide grade with a dedicated chipbreaker for secure chip formation.

• Tiger·tec Silver coating for high process security
• Designed for stainless steel and superalloys machining
• Square 90° insert, 0.8 mm corner radius, negative 0° rake

Robust cutting edge for high‑temperature alloys and stainless steels

The combination of the WSM20S coated carbide grade and the Tiger·tec Silver technology provides enhanced heat resistance and wear protection, which directly benefits machining of tough materials. Materials classified under ISO 513 groups M (stainless steels) and S (heat‑resistant superalloys and titanium) tend to generate high cutting temperatures and adhesive wear; the insert’s coating and grade reduce flank wear and support predictable chip formation, thereby extending tool life and reducing unplanned tool changes. The negative 0° (negative) rake increases edge strength for heavy engagement and interrupted cuts, translating into a more stable machining process.

Consistent surface finish and productive chip control

The integrated NRS chipbreaker is optimised to break and evacuate chips reliably when turning ductile, work‑hardening stainless steels and heat‑resistant alloys. Predictable chip behaviour lowers the risk of surface damage and reduces cycle variability, which is an advantage for series production and quality‑sensitive parts. The insert’s square 90° geometry and 0.8 mm corner radius balance edge robustness with the ability to produce a consistent surface finish, helping to maintain tolerances and decrease downstream finishing operations. This results in improved throughput and measurable productivity gains on the shop floor.

Easy integration into standard tooling systems with reliable repeatability

With the familiar SNMG form factor and the ISO designation supplied, the insert fits established turning toolholders for quick changeover and repeatable clamping accuracy. The grade’s focus on stable chip formation and a durable cutting edge supports longer intervals between tool inspections, contributing to lower overall machining costs and predictable planning. For machine shops working in aerospace, energy or medical sectors where material mixes include stainless steels and superalloys, the insert provides a pragmatic solution that prioritises process security and consistent results.
