DNMG150408-FM5 WSM20S indexable turning insert by Walter Tools — Tiger·tec Silver grade for stainless steels and superalloys

DNMG150408-FM5 WSM20S is an indexable turning insert engineered for demanding applications in stainless steels and heat-resistant superalloys, offering high cutting-edge stability and predictable wear behaviour.

• Tiger·tec Silver grade for durable edges
• Optimised FM5 chipbreaker for stable chips
• Rhombic 55° form, negative 0° rake angle
• 0.8 mm corner radius for consistent finishes

Enhanced edge life where material hostility is highest

The insert uses the WSM20S grade within the Tiger·tec Silver family, a coated carbide designed specifically for the thermal and mechanical stresses of stainless steels and superalloys. The advanced coating promotes stable chip formation and reduces edge build-up, which translates into longer tool life and fewer interruptions in production. For operations where component integrity and repeatability matter, the combination of substrate and coating reduces the risk of premature flank wear and supports consistent dimensional results.

Controlled chip flow and surface quality

The integrated FM5 chipbreaker has been tailored to the insert geometry to ensure controlled chip breaking across typical turning feeds for tough materials. Paired with the rhombic 55° outline and a 0° negative rake, the geometry improves cutting-edge robustness and helps maintain a steady cutting load. The defined 0.8 mm corner radius assists in achieving reliable surface finishes while also distributing cutting forces over a broader edge, lowering the incidence of micro-chipping on interrupted cuts.

Process predictability and productivity gains

Designed for industrial turning tasks in group M and S materials, this insert supports higher process security and fewer unplanned tool changes. The stable cutting edge behaviour afforded by the Tiger·tec Silver technology increases usable edge life, which can result in measurable productivity improvements and reduced tool inventory turnover. For production environments focusing on reproducibility and throughput, the insert provides a reliable baseline for machining strategies in corrosive or heat-resistant alloys.

Clear designation and practical mounting guidance

The designation DNMG150408-FM5 summarises the key geometry: a rhombic 55° plate with the FM5 chipbreaker and a 0.8 mm corner radius, presented in the WSM20S grade of the Tiger·tec Silver series. The insert is supplied in the common DNMG form factor, compatible with standard turning toolholders designed for this plate geometry. Selection of appropriate clamping torque and holder rigidity will complement the insert’s properties and help to realise the intended benefits in finish and edge life.
