TCMT110202-FM4 WSM20S — Triangle indexable insert for stainless steels and superalloys by Walter Tools

A TCMT110202-FM4 WSM20S indexable insert engineered for demanding turning and boring tasks in stainless steels and heat‑resistant alloys, offering secure chip control and high edge stability.

• Tiger·tec Silver coating technology
• Optimised FM4 chipbreaker
• Triangle 60° form for secure clamping
• Suited to stainless and heat‑resistant alloys

Outstanding process reliability for difficult‑to‑cut materials

The combination of the WSM20S grade and Tiger·tec Silver coating focuses on cutting‑edge stability and sustained performance when machining materials that generate heat and tend to work‑harden, such as stainless steels and superalloys. The substrate and coating pairing reduces adhesion and supports consistent chip formation under challenging conditions. For production environments where repeatable surface quality and tool life are priorities, this insert offers a balance between wear resistance and predictable edge behaviour, helping to lower downtime and improve overall throughput.

Precise chip control and geometry that protects the cutting edge

The integrated FM4 chipbreaker has been designed to manage intermittent and continuous chips typical of high‑alloy materials, promoting short, controllable chip forms that evacuate reliably. The triangle 60° plate form and the corner radius 0.2 mm contribute to a robust cutting edge and allow secure clamping in standard toolholders. These geometry choices reduce the risk of built‑up edge and support stable cutting forces, which in turn benefits dimensional reproducibility and surface finish in serial machining.

Practical benefits for workshop integration and process planning

With a designation reflecting ISO indexing and a compact plate size, the insert is straightforward to implement in existing turning and drilling toollines. The combination of grade and chipbreaker makes it suitable for operations where tool change intervals and process stability are critical metrics. Selection of suitable cutting data and coolant strategy will further extend tool life; where high temperatures occur, the coating’s thermal resilience maintains edge integrity. For guidance on cutting parameters, Metav Werkzeuge can assist with material‑specific recommendations to get the best from the insert.

FAQ

What materials is this insert designed for?
The TCMT110202-FM4 WSM20S insert is specified for stainless steels (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), covering applications with high thermal loads and work‑hardening tendencies.

How does the FM4 chipbreaker improve machining performance?
FM4 is engineered to produce short, controlled chips when machining tough alloys, enhancing chip evacuation and reducing the likelihood of built‑up edge, which helps maintain the cutting edge and improve surface finish with the TCMT110202-FM4 WSM20S.

What advantages does the triangle 60° form provide?
The triangle 60° geometry offers three indexable cutting edges per insert and a secure clamping interface, increasing uptime through economical edge changes and delivering stable performance on the TCMT110202-FM4 WSM20S.

Is the Tiger·tec Silver coating beneficial for high‑temperature cutting?
Yes, the Tiger·tec Silver coating improves thermal resistance and reduces adhesion on the cutting edge, supporting longer tool life and steady performance when machining materials that generate significant heat.

Which corner radius is recommended for finishing and semi‑finishing?
The TCMT110202-FM4 WSM20S has a corner radius of 0.2 mm, which is suitable for semi‑finishing and operations where a balance between edge strength and surface quality is required.
