WNMG080412-RM5 WSM20S turning insert — Trigon 80°, Tiger·tec Silver coated, Walter Tools

WNMG080412-RM5 WSM20S is a trigon‑form indexable insert designed for heavy and finish turning of difficult‑to‑machine alloys

• Tiger·tec Silver coated carbide
• Optimised RM5 chipbreaker
• Trigon 80° geometry for stability
• Suitability for rostfreier Stahl and superalloys

Consistent productivity on difficult alloys

The WSM20S grade from the Tiger·tec Silver series combines a multilayer coating with a carbide substrate to deliver improved wear resistance and heat protection. This enables longer cutting times on materials that generate high temperatures and tend to work‑harden, such as rostfreier Stahl and nickel‑based superalloys. The result is fewer tool changes, reduced downtime and a more predictable production flow. The coating technology mitigates abrasive wear and supports a stable cutting edge, which is particularly beneficial when machining parts that demand repeatable surface quality and dimensional accuracy.

Geometry that enhances process reliability

The insert’s Trigon 80° form and 1.2 mm nose radius offer a robust support base and reproducible contact conditions in the cutting zone. The 0° negative relief aids edge strength under interrupted cuts and heavy radial engagement, while the RM5 chipbreaker is tuned to produce controllable, segmented chips across a wide range of feeds. For planners and operators, these features translate into predictable tool behaviour: fewer vibrations, consistent chip evacuation and enhanced edge life. Technical terms: a chipbreaker channels the metal flow into smaller, manageable chips; a negative relief angle increases edge support, improving resistance to chipping during heavy cuts.

Where this insert adds measurable value

This trigon insert is especially suited to CNC turning applications where rostfreier Stahl and heat‑resistant alloys are encountered — for example, aerospace components, fasteners and medical parts where surface integrity matters. The coated carbide grade reduces flank and crater wear, supporting both roughing and semi‑finishing passes. For shops seeking to balance cost and performance, the insert’s combination of coating performance and robust geometry helps lower overall machining costs by extending the number of usable edges per insert and improving first‑pass yields.

FAQ

What materials is this insert suitable for?
The WNMG080412‑RM5 WSM20S is intended for rostfreier Stahl and heat‑resistant superalloys; the WSM20S grade is tuned to maintain a stable cutting edge under high temperatures.

What does the RM5 chipbreaker achieve?
The RM5 chipbreaker controls chip form to enable safe evacuation and reduced tangling, improving surface finish and protecting the toolholder during continuous production.

Is the negative 0° relief suitable for roughing operations?
Yes; the 0° negative relief increases edge support, making the insert resilient under heavier radial depths of cut and intermittent engagement typical of roughing passes.

How does the Tiger·tec Silver series benefit machining performance?
The Tiger·tec Silver coating enhances thermal protection and wear resistance, which prolongs edge life and supports stable machining of demanding alloys.

Can this insert be used for finishing work?
With the 1.2 mm nose radius and the coated grade, the insert performs well in semi‑finishing and finishing operations when appropriate feeds and speeds are applied.
