WNMG080412-NRS WSM20S — Indexable turning insert Trigon 80° for rostfreier Stahl and superalloys | Walter Tools

The WNMG080412-NRS WSM20S is an 80° trigon indexable turning insert engineered for high-process security when machining rostfreier Stahl and heat-resistant superalloys, offering a robust corner radius and a Tiger·tec Silver coated carbide grade.

• Tiger·tec Silver coated carbide grade WSM20S
• Trigon 80° geometry with 0° negative rake
• NRS chipbreaker for secure chip control
• Corner radius 1.2 mm for robust cutting edge

Consistent edge life for demanding materials

The Tiger·tec Silver coating and the WSM20S grade combine thermal stability and wear resistance to extend edge life when machining tough alloys. For applications in rostfreier Stahl and high-temperature superalloys, this coated carbide counters common problems such as workhardening and built-up edge formation. The result is fewer index changes, more predictable tool life and a measurable reduction in production interruptions — supporting process stability and lowering cost per part.

Reliable chip control that improves surface quality

The NRS chipbreaker is shaped to produce short, controllable chips in interrupted or continuous turning, reducing the risk of chip entanglement and protecting the workpiece finish. The Trigon 80° plate form combined with a corner radius of 1.2 mm delivers both strength at the cutting edge and improved surface integrity. Together these features support reproducible surface quality and minimise secondary operations, which benefits throughput and downstream handling.

Designed for secure clamping and machining efficiency

A 0° (negative) free angle and the standard WNMG seating ensure stable insert support in common toolholders, reducing vibration and promoting repeatable cutting conditions. The insert’s geometry and the Tiger·tec Silver technology enable higher cutting parameters on many heat-resistant alloys and rostfreier Stahl, which can translate into increased component output and shorter cycle times. Integration into existing turning setups is straightforward, enabling rapid process optimisation.

Practical advantages for production environments

With a compact plate size and defined tolerance class, the insert fits standard toolholder systems and simplifies inventory management. The combination of coated carbide grade, robust chip control and the trigon form offers a balance between performance and handling safety in industrial turning. For operations that require consistent results across batches, these features contribute to predictable tool behaviour and reduced scrap rates.

FAQ

What materials is this insert suitable for?
The WNMG080412-NRS WSM20S insert is designed primarily for machining rostfreier Stahl and heat-resistant superalloys (ISO groups M and S), where thermal stability and edge control are critical.

How does the NRS chipbreaker affect production?
The NRS chipbreaker on this Walter Tools insert promotes short, manageable chips, which improves workshop safety and reduces downtime associated with chip control and workpiece damage.

Which toolholders are compatible with the Trigon 80° format?
Standard toolholders that accept WNMG‑format trigon inserts are compatible; the insert’s 0° negative free angle and defined seat dimensions ensure stable clamping and repeatable cutting conditions.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances thermal resistance and wear performance of the WSM20S grade, supporting longer tool life and more consistent machining when working with difficult alloys such as rostfreier Stahl and superalloys.

Is this insert suitable for interrupted cuts?
Yes — the combination of a robust corner radius, Trigon 80° geometry and the NRS chipbreaker makes the insert well suited to interrupted and continuous turning operations on challenging materials.
