TCMT090202-FW4 WSM20S – Turning insert, Tiger‑tec Silver coated carbide by Walter Tools (FW4 chipbreaker)

The TCMT090202-FW4 WSM20S is a triangular 60° turning insert engineered for robust machining of stainless steel and heat‑resistant superalloys, offering a balance of edge stability and predictable chip control.

• Tiger‑tec Silver coated carbide grade WSM20S
• Optimised FW4 chipbreaker for secure chip control
• Triangle 60° insert with 0.2 mm corner radius

Reliable performance on demanding alloys

The coated carbide WSM20S grade delivers stable cutting-edge performance when machining materials classified as M (stainless steel) and S (heat‑resistant superalloys and titanium). The Tiger‑tec Silver technology combines a wear‑resistant coating with a substrate designed for thermal resilience, which reduces crater wear and supports continuous operation. For production environments where consistent component tolerances and repeatable surface quality are crucial, this combination means fewer tool changes and less process variation, improving overall throughput and part reliability.

Geometry engineered to improve process security

A triangular 60° form with a 0.2 mm corner radius provides a predictable engagement during turning operations. This geometry, together with the FW4 chipbreaker, promotes controlled chip formation and evacuation, lowering the risk of built‑up edge and tool damage. For users with limited experience of insert geometry, the chipbreaker functions by guiding chips away from the cutting zone and moderating cutting forces, which in turn supports a more consistent surface finish and reduces the likelihood of unplanned stops.

Practical advantages for production economics

Selecting a coated grade with a focus on edge stability reduces the frequency of regrinding or replacement, contributing to a lower cost per part. The compact insert designation and standard ISO form make integration into existing toolholders straightforward, allowing quick replenishment in a busy shop‑floor environment. The optimised wear resistance also supports longer tool life under elevated temperatures common when machining stainless steel, which translates into measurable savings in machine downtime and consumable handling.

Compatibility, handling and quality assurance

The insert is supplied in the standard TCMT format and adheres to expected tolerance class M, ensuring interchangeability across compatible tool systems. The FW4 chipbreaker and the coated carbide composition are intended for medium to heavy interrupted cuts in demanding materials; however, for the best results a trial under representative machining conditions is recommended. Technical documentation for cutting data and recommended feeds and speeds can be provided to support process setup and to help achieve the targeted surface quality and tool life.

FAQ

Is this insert suitable for stainless steel machining?
Yes. The WSM20S grade in the Tiger‑tec Silver series is formulated to manage the heat and toughness typical of stainless steel, providing improved chip control and edge security.

What does the FW4 chipbreaker achieve in practice?
The FW4 chipbreaker promotes reliable chip formation and evacuation, reducing the risk of built‑up edge and helping to maintain consistent surface finish during turning operations.

Which insert geometry is used and why does it matter?
A triangular 60° form with a 0.2 mm corner radius is specified; this geometry balances strength at the cutting edge with accessibility in common turning tasks, supporting stable cutting under variable loads.

Can this insert be used on superalloys and titanium?
Yes, the coating and grade are designed to cope with ISO group S materials; thermal resistance and edge stability make the insert suitable for many superalloy and titanium applications depending on cutting conditions.

Where can cutting data and further technical information be obtained?
Technical cutting parameters and application advice are available from Metav Werkzeuge; they can assist with feeds, speeds and toolholder selection for optimal results with this insert.
