DCGT11T308‑FM2 WSM20S indexable turning insert, Tiger·tec Silver – Walter Tools (for stainless steel and superalloys)

The DCGT11T308‑FM2 WSM20S is an indexable turning insert engineered for stable metal removal in stainless steels and heat‑resistant superalloys, combining a Tiger·tec Silver coating with a robust chipbreaker geometry.

• Tiger·tec Silver coated carbide grade WSM20S
• FM2 chipbreaker for stable chip control
• Rhombic 55° insert with 0.8 mm corner radius
• Optimised for stainless steel and superalloys

Delivering consistent cutting performance for tough alloys

The combination of a Tiger·tec Silver coating and the WSM20S grade provides high resistance to wear and thermal loads encountered in machining stainless steel and nickel‑based alloys. This engineered coating technology improves heat management at the cutting edge and prolongs tool life, which leads to fewer indexings and reduced downtime. In practical terms, the result is a more predictable process with consistent component quality and lower tooling costs per part.

Stable chip control and improved surface finish

The FM2 chipbreaker and the rhombic 55° geometry deliver controlled chip segmentation and evacuation during turning operations. The combination of a 0.8 mm corner radius and a 7° clearance angle supports a reliable cutting edge that reduces the risk of built‑up edge on ductile, work‑hardening stainless steels. Improved chip control directly benefits surface quality and reduces secondary finishing, making the insert suitable for both semi‑finishing and finishing passes.

Productivity through process security and repeatability

Designed for demanding production environments, this insert supports consistent cutting behaviour across batches. The grade’s thermal and edge stability promotes repeatable performance in long runs, helping to reduce scrap and manual rework. By favouring stable chip formation and maintaining a strong cutting edge, the insert contributes to increased machine uptime and predictable machining cycles—key factors in efficient workshop planning.

Geometry and application guidance for reliable setup

With an insert size of 11, T3 thickness and a nominal rhombic 55° form, the geometry enables versatile clamping in standard turning toolholders that accept DCGT‑style inserts. The FM2 breaker is optimised for medium to heavy feeds where controlled chips are required, while the WSM20S grade is especially suitable for the M and S ISO groups (rostfreie Stähle and heat‑resistant superalloys). For best results, combine appropriate cutting speeds and coolant strategy to match the alloy and component rigidity.
