WNMG080404‑FW5 WSM20S indexable turning insert – Tiger‑tec Silver, Trigon 80° (Walter Tools)

The WNMG080404‑FW5 WSM20S is an indexable turning insert engineered for demanding roughing and finishing of stainless steel and Superalloys, offering a coated‑carbide grade optimised for secure chip formation and edge stability

• Tiger‑tec Silver coating for high thermal resistance
• Suitable for stainless steel and Superalloys/Titanium
• Trigon 80° shape for stable cutting and versatility
• FW5 chipbreaker for reliable chip control

Increased process reliability for hard‑to‑cut materials

The coated‑carbide WSM20S grade, part of the Tiger‑tec Silver series, is designed to handle the thermal and mechanical demands of stainless steel and heat‑resistant superalloys. The combination of a wear‑resistant coating and a mechanically stable substrate reduces edge chipping and supports predictable tool life. For workshops seeking measurable uptime improvements, this leads to fewer tool changes and more consistent component tolerances. The material behaviour is explained: superalloys conduct heat poorly and place high strain on the cutting edge, while stainless steel tends to work‑harden; the insert’s design mitigates both effects with enhanced thermal resistance and edge strength.

Consistent chip control and surface quality

The FW5 chipbreaker geometry is tuned to produce short, controllable chips across a range of depths of cut, which simplifies swarf handling and reduces interruption to the turning cycle. The 0° negative rake and 0.4 mm corner radius promote a robust cutting edge that endures interrupted cuts and variable feed conditions, providing a balance between surface finish and tool life. Explained plainly: a negative rake strengthens the edge and resists deformation under heavy loads, while the defined corner radius helps maintain dimensional accuracy at the finished surface.

Practical geometry and machine compatibility

The Trigon 80° form delivers good access for both external turning and light profiling, enabling flexible clamping positions and positive engagement for shoulder and face turning operations. The insert’s nominal size and thickness suit a broad range of toolholders that accept the WNMG family, enabling straightforward integration into existing tool inventories. Where process stability is a priority, the geometry supports reproducible cutting forces, which benefits spindle load management and cycle‑time predictability.

FAQ

What materials is this insert designed for?
This insert (WNMG080404‑FW5 WSM20S from Walter Tools) is intended for stainless steel and for heat‑resistant superalloys and Titanium, reflecting the S / M material designation.

How does the Tiger‑tec Silver coating benefit machining?
The Tiger‑tec Silver coating on the WSM20S grade increases thermal resistance and wear protection, improving edge life and process stability during machining of tough, heat‑generating materials.

Is the FW5 chipbreaker suitable for finishing passes?
Yes, the FW5 chipbreaker provides controlled chip formation and can deliver acceptable surface quality for finishing when combined with appropriate feeds and speeds on the insert.

Which cutting conditions favour this insert?
Robust feeds and moderate to heavy depths of cut suit the 0° negative rake and 0.4 mm corner radius, especially in roughing and interrupted cutting where edge strength and chip control are essential.
