TCMT16T308-FM4 WSM20S – Triangular turning insert, Tiger·tec Silver (Walter Tools)

The TCMT16T308-FM4 WSM20S is a triangular indexable turning insert designed for precision turning and boring in stainless steels and heat‑resistant alloys.

• Tiger·tec Silver coating for heat and wear resistance
• FM4 chipbreaker for stable chip control
• 60° triangular geometry with 0.8 mm nose radius
• Optimised for stainless steels and superalloys

Reliable cutting performance for tough alloys

The combination of a coated carbide substrate and the Tiger·tec Silver technology delivers improved wear resistance and thermal stability when machining difficult materials. The WSM20S grade is formulated to maintain a stable cutting edge under high temperatures, which reduces the risk of built‑up edge and supports consistent cycle times. This results in measurable process stability and contributes to longer effective tool life in production environments.

Geometry engineered for repeatable surface quality

A 60° triangular form with a 0.8 mm nose radius and 7° clearance provides a robust cutting edge that balances strength and finish capabilities. The insert’s tolerance class M and T3 thickness ensure repeatable seating and minimal runout in standard holders, supporting accurate dimensions and surface integrity. These geometric choices make the insert suitable for both medium‑ and finishing cuts where a predictable profile and repeated part quality are essential.

Practical application guidance and process advantages

With a dedicated FM4 chipbreaker, the insert promotes controlled chip formation and evacuation in both stainless steels and superalloys, reducing interruptions and improving cycle productivity. Use the triangular indexable insert in stable toolholders and prioritise rigid setups to exploit the grade’s thermal resistance and edge stability. The result is fewer tool changes and steady component throughput in continuous production or batch machining of demanding materials.
