WNMG060408-RM5 WMP20S Turning indexable insert, Trigon 80°, for rostfreier Stahl — Walter Tools

The WNMG060408-RM5 WMP20S is a negative‑rake, Trigon 80° turning insert engineered for medium to robust turning of rostfreier Stahl, combining the Tiger·tec Silver coating technology with an RM5 chipbreaker for controlled chip formation.

• Tiger·tec Silver coating for enhanced wear resistance
• Optimised RM5 chipbreaker for secure chip control
• Trigon 80° form with 0.8 mm corner radius
• Negative 0° rake for robust turning operations

Consistent performance for demanding rostfreier Stahl machining

The coated carbide grade WMP20S, part of the Tiger·tec Silver family, is developed to manage the typical challenges of rostfreier Stahl: high toughness, built‑up edge tendency and elevated cutting temperatures. The advanced coating supports a stable cutting edge under medium to robust operating conditions, which translates into reliable chip formation and improved process consistency. This results in fewer unexpected interruptions and a more predictable tool life, supporting continuous production workflows.

Geometry that increases stability and repeatability

A Trigon 80° plate with a 0.8 mm corner radius and a 0° negative rake offers a robust edge line that resists chipping and maintains dimensional integrity in interrupted or heavy cuts. The RM5 chipbreaker is optimised for the material group M, producing short, manageable chips and reducing the risk of entanglement at the tool nose. Combined, these geometric features enable dependable results and help to simplify tool selection for repeat operations.

Productivity benefits and application focus

The insert’s specification favours manufacturers seeking balanced performance and process security when turning rostfreier Stahl. The coated grade and chip control geometry allow for sustained cutting conditions that can reduce setup changes and rework. As a component of a well‑engineered tooling system, the insert supports efficient cycle times while helping to protect the machine and workpiece finish, delivering tangible operational advantages in series production and challenging one‑off jobs.

FAQ

What materials is this insert intended for?
The WNMG060408-RM5 WMP20S is specified for machining rostfreier Stahl and is optimised for the particular behaviour of these alloys under cutting.

How does the RM5 chipbreaker influence machining?
The RM5 chipbreaker on this Walter Tools insert promotes secure, short chip formation, which improves chip control and reduces the likelihood of chip entanglement during rostfreier Stahl turning.

Is the negative 0° rake suitable for heavy cuts?
Yes, the 0° (negative) rake angle and Trigon 80° form provide a robust cutting edge that tolerates heavier engagement and intermittent cuts while maintaining edge stability.

What surface finish can be expected with this grade?
When used with appropriate parameters for rostfreier Stahl, the Tiger·tec Silver coated grade delivers consistent edge condition and helps achieve good surface quality along with predictable tool life.

Can this insert be used in automated turning centres?
The geometry and coating make the insert suitable for automated production environments where consistent chip control and repeatability are required for rostfreier Stahl components.
