• 7° clearance and 0.8 mm nose radius

High-performance cutting on difficult materials

The coated WSM20S grade, part of the Tiger·tec Silver family, is engineered for the thermal and mechanical stresses of machining rostfreier Stahl and superalloys. The combination of a wear‑resistant coating and a robust substrate supports a secure cutting edge and predictable wear behaviour, which translates directly into longer tool life and fewer indexings. In practice, this means less downtime for tool changes and a more stable machining process when tackling tough batches or complex workpiece geometries.

Precise chip control for consistent surface quality

Equipped with the FM4 chipbreaker and a Rhombus 55° form, the insert promotes reliable chip formation and evacuation under varying cutting conditions. The FM4 geometry was developed to reduce built‑up edge and encourage segmented chips that are easier to handle in automated cells. As a result, the insert helps to maintain consistent surface finishes and reduces the need for secondary cleaning processes, which benefits throughput and downstream quality checks.

Geometry and edge design that improve process security

A clearance angle of 7° combined with a 0.8 mm corner radius offers a compromise between robustness and finish capability, making the insert suitable for both light finishing passes and more stable medium cutting. The tolerance class M ensures dimensional reliability for repeatable setups, while the rhombic shape enhances access to shoulder and profile features. For engineering teams, this means fewer trial cuts and a shorter ramp‑up when introducing new components into production.

Practical benefits for workshop efficiency

The insert’s coded thickness and size deliver compatibility with common toolholders and permit straightforward inventory management. Because the grade is targeted at high‑temperature and adhesive wear regimes, coolant and parameter optimisation will often extend the effective life further; this produces a favourable cost‑benefit ratio across serial production. Technical teams will value the reduced variability in tool performance, which supports stable cycle times and predictable maintenance planning.
