CNMG120404-NMS WSM20S turning insert — Tiger·tec Silver, NMS chipformer, Walter Tools

The CNMG120404-NMS WSM20S is a rhombic 80° turning insert designed for demanding turning of stainless steel and heat‑resistant superalloys, offering robust edge stability and improved thermal resistance.

• Tiger·tec Silver coating for long tool life
• NMS chipformer for secure chip control
• Suitable for stainless steel and superalloys
• Rhombic 80° shape with 0.4 mm nose radius

Stable performance for stainless steel and demanding alloys

The coated carbide WSM20S grade from the Tiger·tec Silver series is engineered to resist thermal degradation and abrasive wear during continuous turning operations. Its coating technology enhances heat resistance and reduces flank wear, which translates into longer tool life and fewer tool changes for manufacturers working with corrosive or work‑hardening materials. The combination of grade and coating supports predictable tool behaviour under elevated cutting temperatures, enabling tighter process windows and consistent component quality.

Reliable chip control and process security

Built-in chip control is provided by the NMS chipformer, which is optimised for sticky and tough materials. Together with the Rhombic 80° geometry and a 0° (negative) relief angle, the insert ensures stable cutting forces and reduced risk of built‑up edge formation. These features support uninterrupted production runs and make the insert suitable for moderate to heavy cuts where dependable chip evacuation and edge integrity are essential for productivity and part finish.

Improved edge life and surface quality

A 0.4 mm nose radius paired with tolerance class M balances surface finish and robustness: the radius contributes to a superior surface texture while still providing a secure cutting edge for interrupted or unstable feeds. The tolerance class indicates manufacturing precision of the insert, which helps maintain consistent contact between insert and workpiece and reduces variation between assemblies. This results in fewer rework cycles and improved first‑pass yields on turned components.

Broad application range with straightforward handling

With material suitability marked as S / M, this insert covers heat‑resistant superalloys, titanium and stainless steel in accordance with ISO groupings, allowing one grade to address several challenging workpiece materials. The standard CNMG form fits common CNMG toolholders, facilitating straightforward integration into existing tooling systems. For selection of optimal cutting data and holder geometry, consult process data sheets or speak with Metav Werkzeuge’s technical advisers to align insert grade, geometry and cutting parameters with production goals.
