SNMG120404-MM5 WSM20S square turning insert – Tiger·tec Silver, 0° negative rake — Walter Tools

The SNMG120404-MM5 WSM20S is a square indexable turning insert designed for heavy and heat‑generating machining tasks, primarily used in the safe and productive turning of rostfreier Stahl and heat‑resistant superalloys.

• Square 90° geometry for stable cutting
• Tiger·tec Silver coating for heat resistance
• 0° negative rake for heavy depth of cut
• MM5 chipbreaker for secure chip control

Stable cutting for demanding materials

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a coated‑carbide solution optimised for materials that generate heat and resist chip breakage. The substrate and multilayer coating promote stable chip formation, reducing the risk of built‑up edge and enabling longer cutting windows in rostfreier Stahl and nickel‑based alloys. The supplied MM5 chipbreaker improves chip flow under variable cutting conditions; in practice this means fewer interruptions for chip removal and a steadier process, which raises throughput and reduces scrap.

Robust edge geometry that supports productivity

A 0° negative rake combined with a 0.4 mm corner radius gives a mechanically strong cutting edge that tolerates intermittent cuts and higher feed rates. The square 90° plate form with a plate size of 12 (designation code) and thickness code 04 is intended for applications where rigidity is essential. These geometrical choices allow for reliable indexing and repeatable tool set‑up, supporting consistent surface finishes and predictable tool life. For workshops seeking a balance between aggressive metal removal and process security, this configuration reduces rework and supports predictable cycle times.

Reduced downtime through wear resistance and process security

The coated carbide construction and the WSM20S grade combine to resist abrasive and thermal wear, extending the usable life of each insert and lowering tooling cost per component. With a focus on machining rostfreier Stahl and high‑temperature alloys, the insert reduces the frequency of tool changes and contributes to continuous production. Coupled with the brand’s engineering, the insert helps maintain dimensional accuracy throughout longer production runs, improving overall equipment effectiveness and contributing to a more economical machining strategy.
