WNMG080408-RM5 WMP20G Drehwendeschneidplatte — Trigon 80° turning indexable insert, Walter Tools

The WNMG080408-RM5 WMP20G is a Trigon 80° turning indexable insert engineered for machining stainless steel under medium to robust cutting conditions, delivering consistent chip control and edge stability.

• Tiger·tec Gold coating for enhanced wear resistance
• Grade WMP20G optimised for stainless steel machining
• Trigon 80° shape for stable cutting edge
• RM5 chipbreaker for controlled chip formation

Consistent performance for stainless-steel operations

This insert combines a coated carbide grade (WMP20G) from the Tiger·tec Gold series with a geometry tuned for demanding work on stainless steel. The dedicated grade supports stable chip formation and resists edge build-up, which helps maintain process reliability during longer cuts. The insert’s robustness and coating synergy reduce the frequency of edge changes and contribute directly to higher productive uptime and predictable cycle times.

Geometry and chip management that protect the cutting edge

The Trigon 80° form and RM5 chipbreaker work together to provide consistent chip formation and evacuation in materials that tend to produce stringy or adhesive chips. A 0° negative rake creates a more robust cutting edge suited to interrupted or heavy cuts, while the 0.8 mm corner radius increases edge strength and extends service life under abrasive and adhesive conditions. These design choices reduce the risk of premature edge failure and support stable surface quality in serial turning applications.

Practical benefits for shop-floor integration

As an indexable insert with a proven geometry and coating combination, this product offers straightforward integration into existing tooling systems that accept WNMG-style inserts. The WMP20G grade is specified for group M materials according to ISO classifications, making selection simpler for engineers who require assured performance on stainless steel. The controlled tool behaviour reduces rework and supports consistent part quality, which in turn improves labour efficiency and lowers overall production variability.

FAQ

What materials is this insert designed for?
The WNMG080408-RM5 WMP20G insert is specified for stainless steel (ISO group M) and is optimised to manage the typical toughness and heat characteristics of these alloys.

How does the RM5 chipbreaker affect machining on stainless steel?
The RM5 chipbreaker promotes controlled chip formation and evacuation on stainless steel, reducing the risk of built-up edge and improving surface consistency when using the WMP20G grade.

Is the 0° negative rake suitable for heavy cuts?
Yes, the 0° (negative) rake produces a stronger cutting edge that resists chipping under heavier or interrupted cuts, supporting reliability in robust turning operations.

Which toolholders accept this insert type?
This insert follows the WNMG 08 geometry and fits standard toolholders designed for WNMG-style indexable inserts; ensure the clamping seat matches the Trigon 80° form for secure mounting.
