VCMT160404-MM4 WSM20S – Turning insert, Tiger‑tec Silver coating, MM4 chipbreaker (Walter Tools)

The VCMT160404‑MM4 WSM20S is a rhombic 35° turning insert developed for demanding machining of stainless steels and heat‑resistant alloys in precision and production environments.

• Tiger‑tec Silver coated grade WSM20S
• Stable MM4 chipbreaker for controlled chips
• Rhombic 35° form with 0.4 mm corner radius
• Optimised for stainless and superalloys

Reliable edge life through advanced coating and grade

The combination of the Tiger‑tec Silver coating and the WSM20S grade provides improved thermal resistance and wear control compared with uncoated grades. The coated cemented carbide resists abrasive and adhesive wear during interrupted cuts and high temperatures, which extends the service interval and reduces tool change frequency. This translates into a measurable increase in productive cutting time and lower process variability.

Better chip control reduces interruptions and cleaning time

The MM4 chipbreaker is designed to split and curl chips consistently in turning operations, lowering the risk of long swarf and reducing manual clearing. A stable chipflow contributes to uninterrupted production and safer machine operation. For workshop teams, this means fewer stoppages and less time spent removing chips from the workpiece and tooling area, improving overall throughput.

Geometry tuned for versatile turning and surface quality

The rhombus 35° insert form combined with a 0.4 mm corner radius and a 7° relief angle gives a balance between strength and accessibility for near‑shoulder and profiling work. The relatively tight corner radius supports good surface finish while maintaining edge robustness during heavier cuts. The insert’s geometry offers predictable cutting forces, making it suitable for both roughing and finishing tasks where dimensional stability matters.

Broad material coverage and process security

This grade and geometry are intended for machining of group M and S materials according to ISO categorisation: stainless steels (M) and heat‑resistant superalloys and titanium (S). The Walter Tools specification focuses on a secure chip formation and edge stability when temperatures and work‑hardening tendencies challenge the cutting edge. The result is repeatable component quality and consistent tool life across batches.
