VNMG160408-MM5 WSM20S — Turning insert with Tiger·tec Silver coating for stainless steel (Walter Tools)

The VNMG160408-MM5 WSM20S is a rhombic 35° turning insert designed for heavy‑duty turning of stainless steel and heat‑resistant superalloys, offering a negative rake and an MM5 chipbreaker for controlled chip formation

• Tiger·tec Silver coated grade WSM20S
• Optimised MM5 chipbreaker
• Rhombus 35° form with 0° negative rake
• Corner radius 0.8 mm for stable edge life

Reliable performance on difficult‑to‑cut alloys

The WSM20S grade, implemented in the Tiger·tec Silver coating system, is developed for materials that challenge conventional grades. In practice this means improved resistance to thermal degradation and abrasion when cutting stainless steel and heat‑resistant superalloys (ISO groups M and S). The coating and substrate combination supports stable chip formation, reducing the risk of built‑up edge and enabling longer tool life under elevated cutting temperatures. This translates into predictable cycle times and fewer unplanned tool changes for production environments.

Geometry engineered for edge security and surface finish

A compact MM5 chipbreaker and the rhombus 35° form with 0° negative rake provide mechanical robustness where interrupted cuts and tough alloys are encountered. The corner radius 0.8 mm balances edge strength and surface finish: a larger radius increases resistance to edge chipping, while the rhombic geometry maintains access to narrow turning profiles. The coated carbide substrate adds wear resistance without sacrificing toughness, so operators benefit from consistent dimensional accuracy and surface quality across batch runs.

Process security, integration and economic benefits

As an indexable insert, this component reduces setup time and allows rapid index changes compared with brazed tips. The combination of grade and geometry supports productive machining strategies by lowering tool consumption and stabilising process windows. Backed by Walter Tools know‑how and the Tiger·tec Silver technology, the insert is suitable for demanding turning tasks where repeatability and part quality are priorities. Integration into standard toolholders is straightforward, aiding fast adoption on the shop floor and helping to protect throughput in serial production.
