WNMG060404-MM5 WMP20S — Trigon 80° indexable turning insert for stainless steel, Tiger·tec Silver, Walter Tools

WNMG060404-MM5 WMP20S is an indexable turning insert designed for secure, repeatable performance in demanding stainless steel applications, combining a Trigon 80° form with the Tiger·tec Silver coated grade for stable cutting.

• Tiger·tec Silver coated grade WMP20S
• MM5 chipbreaker for controlled chips
• Trigon 80° form for secure seating
• 0.4 mm corner radius for robust edges

Optimised cutting performance for stainless steel

The insert delivers consistent metal‑cutting performance under the specific challenges posed by stainless steel such as high toughness and heat generation. The WMP20S grade, developed within the Tiger·tec Silver family, is a coated cemented carbide designed to improve heat resistance and preserve the cutting edge. This results in more reliable chip formation, reduced risk of built‑up edge and longer effective tool life in medium to robust machining conditions. The combination of grade and coating directly reduces downtime by extending the intervals between indexings and insert changes.

Controlled chips and stable geometry for reproducible surfaces

Chip management and edge strength are central to reproducible machining results. The MM5 chipbreaker is tailored to produce consistent chip shapes when machining stainless materials, which helps to avoid tangling and protects the workpiece finish. The Trigon 80° form provides a compact seating and three usable cutting edges per insert, while the 0.4 mm corner radius increases edge robustness for interrupted or heavier cuts. The 0° (negative) clearance contributes to edge strength and stability, supporting process security when depth of cut or feed varies.

Process reliability and economical operation

By combining a modern coated grade with a conservative, strong geometry, this insert supports stable performance across batch and single‑part production. The construction targets longer edge life and consistent dimensional outcomes, which simplifies tool inventory planning and reduces rework. For operations seeking predictable cycle times and surface quality on stainless steel, the insert offers an economic balance between wear resistance and cutting capability. The proven material and geometry synergy makes it suitable for workshops that prioritise repeatability and low variation in production.

FAQ

Which materials is this insert designed for?
The WNMG060404-MM5 WMP20S insert from Walter Tools is specified for machining stainless steel and is tuned to the typical demands of these materials.

What is the advantage of the Tiger·tec Silver WMP20S grade?
The Tiger·tec Silver WMP20S coated grade provides improved heat resistance and edge stability for tougher cutting conditions, extending effective tool life on stainless steel.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker promotes controlled chip formation with consistent shapes, supporting clean evacuation and improved surface quality during turning operations.

Is the Trigon 80° form suitable for interrupted cuts?
The Trigon 80° geometry together with a 0.4 mm corner radius and a 0° negative clearance increases edge strength, making the insert appropriate for more robust and intermittently loaded cut conditions.

How many cutting edges are available per insert?
The trigon form provides multiple indexable cutting edges per insert; the product designation WNMG060404-MM5 WMP20S indicates the standard indexable insert format used in turning toolholders.
