WNMG080408-MW5 WMP20G — Trigon 80° turning insert, Tiger·tec Gold for rostfreier Stahl | Walter Tools

The WNMG080408-MW5 WMP20G is a negative‑rake Trigon 80° indexable insert engineered for secure cutting of rostfreier Stahl in medium to robust production environments.

• Tiger·tec Gold coating for high wear resistance
• Optimised MW5 chipbreaker for stable chips
• Trigon 80° form with 0.8 mm corner radius
• 0° negative rake for secure cutting performance

Reliable performance with rostfreier Stahl

The combination of the WMP20G grade and Tiger·tec Gold coating provides a balance of hardness and toughness tailored for machining rostfreier Stahl. This coated carbide grade reduces the tendency for built‑up edge and supports consistent tool life under fluctuating temperatures and cutting loads. For users who require repeatable results across batch runs, the insert’s engineered coating and substrate properties contribute to a predictable wear pattern and fewer unplanned tool changes, supporting leaner production cycles.

Geometry designed to control chips and surface quality

The Trigon 80° format and the MW5 chipbreaker work together to produce short, uniform chips and to protect the cutting edge. A 0.8 mm corner radius increases robustness at the cutting edge and helps maintain surface finish where light to moderate feed rates are applied. The 0° negative rake delivers secure engagement in tougher materials, improving stability when encountering variable workpiece conditions. These geometry choices reduce vibration and support a smoother machining process with fewer interruptions.

Coated carbide for temperature and wear management

As a coated carbide solution within the Tiger·tec family, the insert is engineered to manage heat generation and abrasive wear common to rostfreier Stahl machining. The multilayer coating enhances friction behaviour at the tool–chip interface and improves resistance to flank wear, which in turn preserves dimensional accuracy over longer tool life. Process managers seeking consistency will appreciate the improved edge integrity delivered by this specification, which supports reliable component tolerances and surface quality.

Practical advantages for workshop productivity

The insert’s design targets uptime and predictable performance: the MW5 chipformer fosters efficient chip evacuation while the Tiger·tec Gold technology helps to reduce frequency of tool changes. Tolerance class M underlines suitability for standard industrial tolerances in many turning applications. The trigonal format fits common WNMG toolholders, enabling straightforward integration into existing tool systems and quick index changes to maintain throughput. For specific applications or feed‑speed recommendations, technical consultation is available to align cutting data with the production context.
