TCMT16T308-FW4 WSM20S indexable turning insert — Triangle 60°, 0.8 mm radius, Walter Tools

A TCMT16T308-FW4 WSM20S indexable turning insert designed for demanding turning of stainless steel and high‑temperature alloys, featuring a Tiger‑tec Silver coating and an FW4 chipbreaker for stable cutting performance

• Tiger‑tec Silver coating for higher wear resistance
• Optimised FW4 chipbreaker for stable chips
• 0.8 mm corner radius for robust edge life
• Suited to stainless steel and heat‑resistant alloys

Consistent productivity through coating and geometry

The combination of the Tiger‑tec Silver coating and the WSM20S grade provides a reliable foundation for high‑temperature turning tasks. The coating supports thermal resistance and reduces flank wear, which in turn stabilises machining cycles and extends tool life. With the FW4 chipbreaker, chips are formed predictably, lowering the risk of built‑up edge and minimising interruptions. These technical choices translate into measurable process improvements: longer uninterrupted runtime and fewer insert changes, which supports leaner production and reduced throughput variability.

Precision and application flexibility for difficult materials

This insert’s Triangle 60° form and 0.8 mm corner radius create a balance between cutting edge strength and geometric versatility. The modest corner radius reduces edge chipping when machining tough, adhesive materials, while the 7° clearance angle enables consistent contact conditions along the cutting edge. The grade is formulated specifically for stainless steel and for heat‑resistant superalloys and titanium, so the insert is suitable where conventional grades would struggle with heat‑related degradation. Operators benefit from a predictable performance envelope and easier tool selection for challenging workpieces.

Process security, repeatability and shopfloor advantages

The tolerance class M and the standardised geometry ensure straightforward replacement and repeatable part quality across batches. The TCMT16T308-FW4 geometry and T3 thickness are compatible with common turning toolholders, allowing quick index changes and minimal re‑setup times. For production teams this means greater process security, fewer quality deviations and more consistent surface finishes. The result is not only technical reliability but also an economic one: less scrap, reduced rework and a clearer maintenance schedule for tooling stocks.
