CNMG120404-NMS WSM10S Drehwendeschneidplatte – Tiger·tec Silver, for stainless steels and superalloys (Walter Tools)

CNMG120404-NMS WSM10S is a coated cemented‑carbide turning insert designed for robust machining of stainless steels and heat‑resistant superalloys, combining a stable edge with a dedicated NMS chipbreaker for controlled swarf removal

• Tiger·tec Silver coating for high wear resistance
• Optimised for stainless steels and superalloys
• NMS chipbreaker for secure chip control
• Rhombic 80° shape with 0.4 mm corner radius

Consistent performance under thermal and mechanical stress

The CNMG120404‑NMS WSM10S insert benefits from the Tiger·tec Silver coating and a coated carbide substrate, which together deliver improved resistance to abrasive and adhesive wear. Coatings act as a thermal barrier and reduce friction at the cutting zone; this supports a stable cutting edge when machining materials that tend to work‑harden. For workshops processing rostfreie Stähle and superalloys, this combination reduces the frequency of index changes and contributes to steady cycle times.

Controlled swarf and predictable tool life for safer production

The integrated NMS chipbreaker is engineered to produce short, manageable chips when cutting challenging alloys. Effective chip control lowers the risk of entanglement and tool damage, and it simplifies chip evacuation in both wet and dry setups. Because the grade WSM10S is tailored for heat‑resistant materials, the insert maintains edge integrity under elevated temperatures, supporting reproducible tool life and fewer unscheduled interruptions in production.

Robust geometry for versatile turning applications

The rhombic 80° form with a 0.4 mm corner radius and a negative rake of 0° provides a balanced combination of strength and versatility. A larger corner radius improves edge stability in medium to heavy cuts, while the 80° shape offers favourable approach angles for external turning and profiling. The nominal plate size 12 and plate thickness 04 ensure compatibility with common CNMG toolholders, making the insert a practical choice for operations that need both durability and dimensional control.
