SCMT09T308-FM4 WSM30S — Indexable turning insert with Tiger·tec Silver coating for stainless steels and superalloys | Walter Tools

The SCMT09T308-FM4 WSM30S is a square 90° turning insert optimised for stable cutting in stainless steels (M) and heat‑resistant superalloys/titanium (S), combining a FM4 chipbreaker with a strong 0.8 mm corner radius for secure machining

• Tiger·tec Silver coated for high temperature resistance
• Stable edge geometry for stainless steels M
• FM4 chipbreaker for dependable chip control
• Square 90° form with 0.8 mm corner radius

Maximise productivity on tough materials with proven coating technology

The SCMT09T308‑FM4 WSM30S insert is built around the Tiger·tec Silver coating and the WSM30S grade, which together improve thermal resistance and wear behaviour when machining difficult‑to‑cut alloys. This combination reduces the risk of built‑up edge and supports a stable cutting edge, translating into longer tool life and fewer interruptions. For workshops processing stainless steels and high‑temperature alloys, the result is a measurable increase in productivity and predictable performance under sustained loads.

Confident chip control and process reliability for consistent surface quality

Equipped with the FM4 chipbreaker, the insert controls chips reliably in medium to heavy turning operations, reducing rework and machine downtimes. The square 90° geometry and the 0.8 mm corner radius provide a strong cutting edge that resists chipping and maintains form tolerances over longer series runs. This leads to consistent surface finishes and repeatable components—key for precision production environments that demand both accuracy and throughput.

Practical design that supports easy integration and safer machining

With a 7° clearance angle and a standard SCMT format, the insert fits established toolholders and clamping systems, enabling quick tool changes and minimal setup time. The WSM30S grade is specifically tuned for the thermal and mechanical loads of stainless steels (M) and superalloys (S), offering a balance between edge toughness and wear resistance. Shops seeking dependable turning performance will find this insert a pragmatic choice for demanding applications where stability and process security matter.
