TCMT16T304‑FW4 WSM20S indexable turning insert — Tiger·tec Silver, FW4 chipbreaker (Walter Tools)

A TCMT16T304‑FW4 WSM20S indexable turning insert engineered for heavy‑duty machining of stainless steel and heat‑resistant superalloys, offering Tiger·tec Silver coating and a proven FW4 chipbreaker for stable production.

• Tiger·tec Silver coating for high temperature stability
• Optimised for stainless steel and superalloys
• FW4 chipbreaker for consistent chip control
• 0.4 mm corner radius for fine surface finishes

Greater process reliability with advanced grade and chip control

The coated carbide WSM20S, utilising Tiger·tec Silver technology, is designed to maintain a stable cutting edge under high thermal load, which directly improves productivity in continuous turning operations. Combined with the FW4 chipbreaker, the insert supports predictable chip formation and fewer interruptions for chip clearing. This results in a measurable reduction in downtime and more consistent component quality when working with stainless steel and similar difficult‑to‑cut materials.

Geometry that balances durability and surface quality

A triangle 60° configuration with a 0.4 mm corner radius and a 7° relief angle provides a stable contact geometry that resists chipping while enabling fine surface finishes where required. The specified plate thickness T3 contributes to stiffness at the cutting edge, reducing vibration and maintaining dimensional accuracy over longer tool life. These geometric choices help deliver repeatable results on batch production and small series alike.

Versatile application scope and user benefits

This insert is suitable for machining in the ISO groups M and S — specifically stainless steel and heat‑resistant superalloys/titanium — offering a practical solution where thermal resistance and edge stability are critical. The combination of a coated carbide substrate and a dedicated chipbreaker supports a broad range of cutting parameters, allowing shops to increase material removal rates without compromising surface integrity. Compatibility with standard triangular toolholders makes implementation straightforward in existing turning toolbanks.

FAQ

What materials is this insert best suited for?
The TCMT16T304‑FW4 WSM20S indexable turning insert (Walter Tools, SKU TCMT16T304‑FW4‑WSM20S‑WALTER) is optimised for stainless steel and heat‑resistant superalloys, reflecting the WSM20S grade focus.

How does the FW4 chipbreaker affect machining performance?
The FW4 chipbreaker on this insert promotes consistent chip formation and evacuation, which improves process stability and reduces the risk of built‑up edge on the WSM20S coated carbide grade.

Can the insert provide fine surface finishes on stainless parts?
Yes; the combination of the triangle 60° geometry and a 0.4 mm corner radius supports fine surface quality while maintaining edge robustness during turning of stainless steel components.
