WNMG100608-MM5 WMP20G indexable turning insert — Trigon 80°, 0.8 mm radius — Walter Tools

WNMG100608-MM5 WMP20G is an indexable turning insert designed for reliable machining of stainless steel components in medium to robust conditions

• Tiger·tec Gold coating for durability
• Optimised chip control MM5
• Trigon 80° shape for stable cutting
• Suitable for stainless steel (ISO M)

Durable coating and grade for consistent cuts

The combination of the Tiger·tec Gold series and the WMP20G grade provides a coated-carbide chemistry optimised for machining stainless steel. This pairing enhances resistance to flank wear and supports stable chip formation, which reduces the frequency of tool changes and contributes to predictable cycle times. In production environments where repeatability matters, the coating and grade work together to maintain a consistent cutting edge under elevated temperatures typical for austenitic stainless materials.

Geometry engineered for strength and surface quality

A Trigon 80° insert form with a 0° (negative) clearance and a 0.8 mm corner radius gives the insert mechanical robustness and edge support. The trigon shape increases effective cutting edge engagement, improving tool life on interrupted cuts and heavy cross-sections. The larger corner radius helps to deliver improved surface finish and avoids premature edge breakdown when machining tough, work-hardening stainless alloys.

Chip control and process security with MM5 breaker

The integrated MM5 chipbreaker is tuned to the material group ISO M and promotes short, manageable chips during turning of stainless steels. Reliable chip control reduces the risk of re-cutting and workpiece damage, which in turn supports safer automatic machining and less downtime. For shops aiming to increase throughput, the chip management contributes directly to higher process security and fewer secondary operations.

Practical application and benefits for production

This insert suits turning operations where mechanical strength and edge stability are priorities—such as roughing and semi-finishing of stainless-steel parts. The coated carbide construction and the chosen breaker geometry make it a pragmatic choice for mixed-series production, balancing cutting performance with predictable tool life. For precise parameter setting or integration into existing toolholders, Metav Werkzeuge’s technical team can advise on optimal speeds and feeds based on the component alloy and machine capabilities.
