CNMG120412-NMT WSM20S — Walter Tools turning insert, Tiger‑tec Silver coated for stainless steels and superalloys

The CNMG120412-NMT WSM20S is a rhombic 80° turning insert engineered for heavy‑duty and heat‑resistant material machining, offering a coated carbide grade optimised for stable cutting in demanding production environments

• Tiger‑tec Silver coating for high wear resistance
• Optimised for stainless steels and superalloys
• Negative 0° relief for robust cutting performance
• Rhombic 80° shape with 1.2 mm corner radius

Precision coating and material compatibility for consistent results

The combination of the Tiger‑tec Silver technology and the WSM20S grade yields a coated carbide structure designed to resist abrasive wear and thermal loading. This makes the insert particularly effective when machining stainless steels and heat‑resistant superalloys, where adhesion and high temperatures challenge tool life and part quality. The coating supports stable chip formation, which reduces the likelihood of edge build‑up and helps maintain a predictable tool life; as a result, process stability and component repeatability are improved without relying on frequent tool changes.

Robust insert geometry that supports secure cutting

Built with a rhombic 80° profile and a negative 0° relief, the geometry of this insert prioritises strength at the cutting edge and tolerance to interrupted cuts. The corner radius 1.2 mm increases edge robustness, enabling more aggressive feeds where appropriate, while the NMT chipbreaker promotes manageable chip control across variable depths of cut. Together, these characteristics reduce the risk of edge chipping and contribute to a steady surface finish on demanding workpieces, supporting predictable cycle times in series production.

Practical application advice and productivity benefits

Belonging to the Tiger‑tec Silver series and specified for material groups S / M, this insert is intended for components made from superalloys and stainless steels where heat generation and work‑hardening are factors. The grade's design emphasises process security and reliable tool life, which can lower tooling costs per part in the medium to long run. If machining parameters or material conditions are unclear, Metav Werkzeuge can provide application guidance and cutting data to match the insert to the machine and workpiece.
