CNMG120408-FM5 WSM10S turning indexable insert — Tiger·tec Silver, FM5 chipbreaker (Walter Tools)

The CNMG120408-FM5 WSM10S is a rhombic 80° turning insert engineered for demanding machining of stainless steel and heat-resistant superalloys in industrial turning operations.

• Tiger·tec Silver coating for heat resistance
• WSM10S grade for stainless steel and superalloys
• Rhombic 80° form for versatile turning
• 0° negative rake for stable cutting
• 0.8 mm nose radius for consistent surface quality

Reliable performance on stainless steel and superalloys

The Tiger·tec Silver WSM10S grade is formulated for materials that challenge conventional carbide, in particular stainless steel and heat-resistant alloys. The coated cemented carbide composition provides improved thermal stability, which means the cutting edge is less prone to rapid wear under elevated temperatures. In practice, this enhances process reliability and supports longer intervals between tool changes, so machining cycles become more predictable and production planning is simplified.

Geometry that secures chip control and surface finish

The rhombic 80° geometry combined with the FM5 chipbreaker and a 0° negative rake angle produces controlled chip formation and a stable cutting action. The 0.8 mm nose radius contributes to repeatable surface finishes while maintaining strength at the tip; this balance reduces the risk of edge chipping during interrupted cuts. Where surface integrity and dimensional consistency matter, the insert’s geometry translates directly into measurable part quality improvements.

Economical lifecycle and reduced downtime

Coating technology and a stable cutting-edge design result in longer tool life and fewer unplanned interruptions. Reduced edge wear and predictable regrinding requirements deliver a positive cost-in-use effect across production batches. Because the insert supports secure chip evacuation and heat resistance, the operational window for feeds and speeds becomes wider, enabling productivity gains without compromising component tolerances.

Practical application and compatibility

Designed for standard CNMG toolholders, the insert suits a range of turning operations from medium to heavy machining where stainless steel or S-group alloys are encountered. The coded designation reflects the ISO-style format for insert exchange and tool inventory management, enabling straightforward replacement and traceability in toolrooms. For process integration, cutting data should be aligned with the workpiece alloy and machine rigidity to leverage the full benefit of the Tiger·tec Silver technology.

FAQ

Is this insert suitable for machining stainless steel? Yes. The CNMG120408-FM5 WSM10S is specified for stainless steel and is produced in the Tiger·tec Silver technology to improve thermal resistance and chip behaviour.

What does the WSM10S grade indicate? WSM10S denotes a Walter Tools carbide grade within the Tiger·tec Silver family, optimised for heat resistance and stable cutting edges when machining stainless steel and heat-resistant alloys.

Which chipbreaker is fitted and what benefit does it bring? The FM5 chipbreaker is integrated to encourage consistent chip formation and evacuation, reducing the likelihood of built-up edge and aiding surface finish consistency.

Can the insert be used in standard CNMG toolholders? Yes. The designation corresponds to the CNMG geometry and is compatible with holders designed for CNMG-style indexable inserts.

How does the 0° negative rake affect machining? A 0° negative rake provides a robust cutting edge suited to tough materials and intermittent cuts, improving edge stability at the expense of slightly higher cutting forces compared with positive rake alternatives.
