TCMT090204-FW4 WSM20S – Triangle 60° indexable turning insert for stainless steels and superalloys (Tiger·tec Silver, Walter Tools)

The TCMT090204-FW4 WSM20S is a 60° triangular indexable turning insert designed for demanding machining tasks in stainless steels and heat-resistant alloys; it pairs a robust coated carbide grade with a secure chipbreaker to maintain process stability.

• Tiger·tec Silver coated carbide WSM20S
• Triangle 60° form with 0.4 mm radius
• FW4 chipbreaker for secure chip formation
• Suited for stainless steels and superalloys

High-performance grade that extends tool life and process reliability

The coated carbide WSM20S grade, based on Tiger·tec Silver technology, is formulated for the thermal and mechanical loads typical of stainless steels and heat-resistant superalloys. Its multilayer coating enhances edge stability and reduces abrasive wear, which translates into longer intervals between index changes and fewer unplanned stoppages. In practice, the result is a more consistent surface finish and reduced tooling consumption for serial and small-batch production alike, improving overall machining economy without sacrificing precision.

Controlled chip formation and safer machining for difficult materials

The FW4 chipbreaker geometry supports reliable chip control when turning materials that tend to produce long or stringy swarf. Combined with the insert’s 0.4 mm corner radius, the system promotes stable cutting forces and predictable chip shapes, which lowers the risk of built-up edge and chatter on semi-finished components. For operators, this means fewer interruptions for swarf management and more repeatable cycles when machining shafts, rings or complex contours in demanding alloys.

Geometry and tolerance that simplify process setup and reproducibility

The 60° triangular form offers three indexed edges per insert, delivering cost-effective cutting edge utilisation. The specified free angle of 7° and the tolerance class M contribute to consistent engagement and minimal seat distortion in conventional toolholders. This combination supports a straightforward parameter window for spindle speeds and feed rates when switching between batches or workpiece materials, making it easier to standardise process sheets and maintain reproducible part quality.
