WNMG060404-MM5 WSM20S — Trigon 80° turning insert, Tiger·tec Silver, Walter Tools

The WNMG060404-MM5 WSM20S is a Trigon 80° turning insert developed for demanding turning operations on stainless steel and heat-resistant superalloys, offering a balance of edge stability and controlled chip formation.

• Tiger·tec Silver coated carbide
• WSM20S grade for tough alloys
• Trigon 80° form, 0.4 mm corner
• Chipbreaker MM5 for stable chips

High-performance machining where stability matters

The insert’s Tiger·tec Silver technology and WSM20S grade provide a hardwearing, coated carbide cutting edge engineered for materials that generate heat and strain the tool edge. The chipbreaker MM5 promotes predictable chip formation, which reduces interruptions and the risk of built-up edge when machining stainless steel or nickel-based alloys. Explained simply: the coating increases thermal resistance and edge life, while the chipbreaker geometry shapes and ejects swarf to maintain a steady cut — a direct benefit to throughput and tool change intervals.

Consistent surface quality and reduced rework

A Trigon 80° form combined with a 0.4 mm corner radius delivers a robust cutting geometry that supports repeatable finishes on complex workpieces. The negative 0° relief helps absorb cutting forces during heavier cuts, so dimensional stability is improved and secondary finishing steps are less frequent. The tolerance class M ensures batch-to-batch uniformity, which is especially valuable for serial production where interchangeability and predictable tool behaviour translate into lower scrap rates and higher overall equipment effectiveness.

Integration into the workshop and application guidance

The insert is designed for standard WNMG toolholders and is available in the established WNMG060404-MM5 format, facilitating straightforward replacement and setup in turning centres. Material suitability is indicated by ISO groups M and S, meaning primary applications are stainless steel and heat-resistant superalloys or titanium alloys; this informs tool selection and machining strategies without the need for extensive trial runs. For difficult-to-machine alloys, combining the WSM20S grade with stable fixturing and appropriate coolant strategy improves process security and surface integrity.
