TCMT110204-FW4 (TCMT110204-FW4 WSM20S) WSM20S Turning insert — Tiger·tec Silver coating, FW4 chipbreaker, for stainless steels and superalloys (Walter Tools)

The TCMT110204-FW4 WSM20S is a coated carbide triangle insert engineered for secure material removal in stainless steels and heat‑resistant superalloys, offering a balance of edge stability and chip management in demanding turning operations.

• Tiger·tec Silver coated carbide for longevity
• FW4 chipbreaker for consistent chip control
• Triangle 60° geometry with 0.4 mm corner radius
• Optimised for stainless steels and superalloys

Durable coating for consistent edge life and process stability

The Tiger·tec Silver coating and the WSM20S grade combine to provide a coated carbide solution optimised for difficult‑to‑machine alloys. This surface technology increases thermal resistance and wear performance, which translates into more predictable tool life under elevated cutting temperatures. For production environments where downtime is costly, the coating supports stable cutting and reduces the frequency of insert changes, improving overall process efficiency.

Geometry and chip control that reduce rework and improve surface integrity

The triangle 60° shape with a 0.4 mm corner radius and the FW4 chipbreaker are designed to generate reliable chip forms when turning ductile and work‑hardening materials. The moderate corner radius helps to distribute cutting forces and produce a controlled cutting edge, while the chipbreaker guides swarf away from the cutting zone. Together these features help to lower the risk of built‑up edge and enhance surface finish, especially in interrupted cuts or variable feeds.

Application range and machining advantages for stainless steels and superalloys

Classified for ISO groups M and S, this insert is suitable for rostfreie Stähle and heat‑resistant superalloys or titanium where conventional grades struggle with heat and edge stability. The insert’s tolerance class M indicates machining performance balanced between form accuracy and robustness, making it suitable for both roughing and semi‑finishing passes. Using the correct feed and cutting speed reduces thermal load on the edge and maximises the benefit of the Tiger·tec Silver technology.

Practical setup guidance to achieve repeatable results

A modest 7° clearance angle and the insert thickness coded as 02 ensure compatibility with a broad range of toolholders; verify holder seat and clamping to maintain runout within specification. Select speeds and feeds according to the workpiece alloy and machine rigidity: lower cutting speeds and slightly higher feeds often reduce heat concentration on the cutting edge for stainless steels. For process development, document the achieved tool life and surface quality to refine cutting parameters and secure reproducible productivity gains.

FAQ

What materials is this insert designed for?
The TCMT110204-FW4 WSM20S is specified for rostfreie Stähle (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), combining coating and grade to cope with high thermal stress.

How does the FW4 chipbreaker affect machining?
The FW4 chipbreaker promotes consistent chip shapes and evacuation, reducing the likelihood of entanglement and improving process stability during turning with the Walter Tools insert.

What is the corner radius and why does it matter?
The insert has a 0.4 mm corner radius, which balances strength and surface quality—larger radii improve edge robustness, while smaller radii enable finer finishing.

Is the insert compatible with standard toolholders?
The geometry (triangle 60°) and thickness code (02) are standard for many turning holders; correct clamping and seat condition are essential to preserve dimensional accuracy and tool life.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver increases thermal resistance and wear performance, supporting longer intervals between indexings and more reliable outcomes in demanding turning tasks.
