WNMG080412-RM5 WMP20S — Trigon 80° turning insert for stainless steel, Tiger·tec Silver, Walter Tools

WNMG080412-RM5 WMP20S is a trigon turning insert optimised for machining stainless steel under medium to robust conditions, offering secure chip formation and wear resistance.

• WMP20S grade for stainless steel
• Tiger·tec Silver coating for wear resistance
• Trigon 80° form with 1.2 mm corner
• Negative 0° rake for robust edge

Consistent performance for stainless‑steel turning

The coated carbide WMP20S grade from the Tiger·tec Silver family is formulated to support reliable machining of stainless steel, where built‑up edge and heat generation can compromise results. The coating improves wear resistance and reduces friction at the cutting zone, which enhances process stability and extends cutting edge life. For workshops requiring predictable cycles and fewer tool changes, this insert offers a measurable benefit in uptime and component quality by promoting secure chip formation under mixed cutting conditions.

Geometry and edge design that resist edge degradation

The Trigon 80° plate form combined with a 1.2 mm corner radius delivers a sturdy cutting edge that tolerates interrupted cuts and higher radial forces. The negative 0° rake results in a reinforced edge angle, improving resistance to chipping when machining tougher stainless grades. The RM5 chipbreaker is tuned for controlled chip morphology in these materials, reducing entanglement and aiding evacuation. In practical terms, this geometry supports both stable roughing and reliable finish passes where edge integrity is critical.

Productivity and application advantages in everyday use

Designed for a broad band of stainless‑steel applications, the insert supports efficient turning in environments where consistency and repeatable results matter. The combination of grade and geometry reduces the frequency of edge deterioration, which in turn lowers process variability and scrap risk. Integration into standard indexable toolholders is straightforward, enabling quick indexing and minimal downtime. For manufacturers seeking a balance between tool life and machining performance, this indexable insert contributes to steadier cycle times and improved part surface quality.
