DCMT11T308-RM4 WSM20S indexable insert — Tiger·tec Silver for stainless steel — Walter Tools

DCMT11T308-RM4 WSM20S is a rhombic 55° indexable insert designed for demanding turning operations in stainless steel and heat-resistant superalloys

• Tiger·tec Silver coated for extended edge life
• Optimised RM4 chip control for stable cutting
• Rhombus 55° geometry for versatile turning
• 0.8 mm corner radius for improved strength

High-performance cutting for difficult-to-machine alloys

The WSM20S grade, based on Walter Tools’ Tiger·tec Silver coating technology, is formulated for machining stainless steel and heat-resistant superalloys. Its combination of a coated-carbide substrate and advanced surface layers promotes stable chip formation and reduces built-up edge under thermal stress. For production environments where reproducible component quality and predictable tool life are required, this insert supports consistent throughput with fewer interruptions and reduced rework

Coating and edge life that pay off in practice

A modern coated carbide grade provides both thermal protection and mechanical strength; the Tiger·tec Silver system is engineered to resist crater wear and flank degradation during prolonged contact with hot, adhesive materials. The insert’s 0.8 mm corner radius increases edge robustness, leading to improved surface integrity and fewer edge failures on interrupted cuts. This results in lower tool consumption per part and a measurable improvement in overall machining economy

Geometry and chip control for dependable process behaviour

The rhombic 55° shape and RM4 chipbreaker deliver controlled chip segmentation and reliable chip evacuation across a range of feeds. Combined with the insert’s clearance angle of 7° and its T3 thickness, the geometry provides a predictable contact pattern that reduces vibration and supports fine surface finishes. These geometric characteristics make the insert suitable for medium-duty finishing and general turning tasks where dimensional stability matters

Application guidance and system compatibility

Recommended for the ISO material groups M (stainless steels) and S (heat-resistant superalloys and titanium), the insert performs best when paired with rigid toolholders and stable machine setups. The specifier benefits from a solution that balances wear resistance with edge stability, especially on components where thermal loading is high. For detailed holder matching and optimal cutting parameters, Metav Werkzeuge’s technical consultants can provide tailored recommendations based on the machining scenario
