CNMM120408-HU5 WMP20S — Indexable turning insert (Rhombic 80°, 0.8 mm) by Walter Tools

The CNMM120408-HU5 WMP20S is an indexable turning insert engineered for robust machining of stainless steels under moderate to heavy cutting conditions.

• Tiger·tec Silver coated for stable edges
• Optimised HU5 chipbreaker for secure chip control
• Rhombic 80° geometry for versatile turning
• 0.8 mm corner radius for durable tool life

High process reliability through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WMP20S cemented carbide grade provides consistent performance when machining stainless steel. The coating reduces friction and helps maintain a stable cutting edge at elevated temperatures, which minimises the risk of built-up edge and enhances surface finish. As an indexable insert, this part offers repeatable positioning and predictable wear behaviour, translating into fewer tool changes and improved machine uptime — a clear rational advantage for production-focused environments.

Geometry and chip control that protect cycle time

The insert’s rhombic 80° shape and integrated HU5 chipbreaker are designed to promote reliable chip formation and evacuation when cutting tough, ductile stainless steels. The 0.8 mm corner radius gives a strong cutting edge that resists chipping under moderate interruption or heavier cuts, while the 0° (negative) rake supports robust engagement and dimensional stability. These technical choices align to reduce unscheduled stoppages and maintain consistent cycle times, supporting predictable throughput and cost-efficiency.

Practical benefits for workshop integration and part quality

With a focus on process security and ease of handling, the CNMM120408-HU5 WMP20S insert simplifies tool inventory thanks to its standard ISO designation and familiar geometry. The optimised chip control lowers thermal loading at the edge, which helps achieve more consistent surface quality and lengthens time between tool indexings. For engineering teams that prioritise reproducibility and low rework rates, this insert contributes directly to reduced scrap and higher first-pass yield, reinforcing both operational and quality objectives.
