VNMG160404-MM5 WSM20S indexable turning insert — Tiger·tec Silver for stainless steels and superalloys (Walter Tools)

A VNMG160404-MM5 WSM20S indexable turning insert engineered for heavy and interrupted cuts in stainless steels and heat‑resistant superalloys, featuring a rhombic 35° geometry and a robust MM5 chipbreaker.

• Tiger·tec Silver coated carbide grade WSM20S
• Optimised MM5 chipbreaker for stable chips
• Rhombic 35° shape, 0.4 mm corner radius

High‑performance grade for challenging materials

The WSM20S grade from the Tiger·tec Silver series delivers a balance of hardness and toughness tailored for materials in groups M (stainless steels) and S (heat‑resistant superalloys and titanium). The coating improves thermal resistance and reduces flank wear, so productivity can be raised without sacrificing edge life. This technical composition supports a consistent cutting edge under elevated temperatures and offers predictable tool life in demanding turning operations.

Geometry and edge design that stabilise the process

The rhombic 35° insert form combined with a 0° negative relief creates a compact, rigid cutting geometry that resists deflection during heavy cuts or interrupted conditions. The 0.4 mm corner radius increases edge strength for improved surface integrity and reduced chipping risk. In addition, the MM5 chipbreaker is optimised for secure chip formation, reducing tangling and facilitating coolant flow, which together enhance machining stability and minimise secondary operations.

Productivity gains and application guidance

Used in appropriate toolholders, this insert supports higher metal removal rates and longer tool cycles on tough alloys, translating into lower cycle times and fewer tool changes. The combination of grade, coating and chip control is particularly suited to industrial applications where consistent surface finish and process security matter. For an efficient set‑up, choose cutting parameters aligned with material group recommendations and verify feed and speed gradually to exploit the insert’s thermal and mechanical robustness.

FAQ

What materials is this insert best suited for?
The VNMG160404‑MM5 WSM20S from Walter Tools is optimised for stainless steels (ISO group M) and heat‑resistant superalloys/titanium (ISO group S).

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker promotes short, controlled chips and supports coolant evacuation, improving process reliability and reducing the risk of chip entanglement during turning operations.

Why choose Tiger·tec Silver grade WSM20S?
WSM20S offers a coated cemented carbide balance that enhances thermal stability and wear resistance, giving more predictable tool life when machining tough alloys.

Is the rhombic 35° geometry suitable for heavy cuts?
Yes. The 35° rhombic form with a 0° negative relief provides a rigid cutting edge that withstands higher cutting forces and interrupted cuts.
