TNMG160404-FW5 WSM20S – Indexable turning insert, Tiger‑tec Silver, FW5 chipbreaker (Walter Tools)

The TNMG160404-FW5 WSM20S is a triangular indexable turning insert engineered for demanding turning of stainless steels and superalloys, offering a stable cutting edge and controlled chip formation for production environments.

*Tiger‑tec Silver coating for high thermal stability
*WSM20S grade for stainless and superalloys
*Triangle 60° shape, 16 mm inscribed circle
*FW5 chipbreaker with 0.4 mm corner radius

Reliable chip control for demanding materials

The combination of the FW5 chipbreaker and the WSM20S grade ensures consistent chip formation when machining materials prone to built‑up edge and poor thermal conductivity. The insert’s chipformer geometry reduces interruptions in the cutting process and helps maintain a steady material flow, which lowers the risk of workpiece damage and reduces rework. The underlying coated carbide substrate stabilises the cutting edge under fluctuating heat loads, translating into fewer indexings and more uninterrupted production time.

High process security and extended tool life

The Tiger‑tec Silver coating boosts thermal resistance and wear protection, supporting a broad range of cutting conditions typical in stainless and heat‑resistant alloy machining. This combination provides improved flank and crater wear behaviour, which contributes to reproducible surface quality and predictable tool change intervals. For operations that prioritise throughput and repeatability, the grade and coating deliver a measurable advantage in maintaining cutting performance across batches.

Geometry designed for versatile turning operations

Geometry features such as the triangle 60° form, 16 mm inscribed circle and 0.4 mm corner radius enable balancing strength and accessibility in both semi‑finishing and roughing passes. The insert’s negative 0° relief angle offers a robust cutting edge for heavier cut engagements, while the tolerance class M supports consistent seating in compatible toolholders. These dimensional and tolerance attributes make the insert suitable for standard turning tool systems where rigidity and process reliability are essential.
