WNMG080408-FM5 WMP20S indexable turning insert — Tiger·tec Silver for rostfreier Stahl (Walter Tools)

The WNMG080408-FM5 WMP20S is a Trigon 80° indexable insert designed for medium to robust turning applications in rostfreier Stahl, offering coated carbide performance and a secure chip control geometry.

• Tiger·tec Silver coating for tougher edges
• WMP20S grade optimised for rostfreier Stahl
• Trigon 80° geometry with 0.8 mm corner radius
• FM5 chipbreaker for secure chip control

Reliable performance in rostfreier Stahl turning

The combination of the Tiger·tec Silver coating with the WMP20S grade delivers improved resistance to wear and heat, which is crucial when machining rostfreier Stahl. Coated carbide reduces the tendency for built-up edge and supports stable chip formation, so that cutting forces remain predictable and tool life is extended under medium to robust cutting conditions. This stability leads to fewer interruptions in production and a more consistent surface finish, helping to maintain throughput in demanding workflows.

Geometry engineered for edge security and productivity

The insert’s Trigon 80° form and 0.8 mm corner radius provide a mechanically strong cutting edge that tolerates intermittent engagement and elevated loads. A 0° (negative) free angle increases edge support, reducing chipping risk under rough conditions, while the FM5 chipbreaker promotes reliable chip control across a range of depths of cut. In practice, these geometry choices translate into reduced downtime for insert changes and a lower risk of unexpected scrap, supporting a more economic machining process.

Practical application and integration guidance

Suitable for medium to robust cutting tasks in rostfreier Stahl, this insert is intended for both serial production and smaller batch runs where edge life and process security are priorities. The coated carbide construction adapts well to elevated temperatures associated with stainless machining; practitioners will appreciate the balance between wear resistance and toughness inherent to the grade. For specific tool-holder compatibility or feed and speed suggestions, Metav Werkzeuge can provide targeted advice to integrate the insert into existing tool lines and machining cycles.

FAQ

What materials is this insert designed for?
The WNMG080408-FM5 WMP20S insert is optimised for machining rostfreier Stahl and is specified for medium to robust cutting conditions.

How does the FM5 chipbreaker affect machining?
The FM5 chipbreaker on the WNMG080408-FM5 WMP20S enhances chip control and reduces the risk of long, tangled chips, improving process reliability during turning operations.

What does the 0° (negative) free angle mean for edge life?
A 0° (negative) free angle increases edge support, which reduces susceptibility to chipping under heavy loads; this contributes to longer, more predictable tool life for the WNMG080408-FM5 WMP20S.

Is this insert suitable for interrupted cuts?
Yes, the Trigon 80° geometry with a 0.8 mm corner radius and a negative free angle makes the insert well suited to interrupted and robust turning tasks.
