WNMG080404-FM5 WMP20S — Tiger·tec Silver Trigon 80° turning insert by Walter Tools

The WNMG080404-FM5 WMP20S is a trigon‑shape indexable turning insert designed for medium to heavy machining of rostfreier Stahl, featuring the Tiger·tec Silver coating and FM5 chipbreaker

• WNMG080404-FM5 WMP20S turning insert
• Tiger·tec Silver coating for stable edge
• Designed for rostfreier Stahl machining
• Trigon 80° shape with 0.4 mm corner radius

Longer tool life in demanding stainless applications

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade delivers improved wear resistance and stable cutting edges when working with rostfreier Stahl. Coating technology reduces the thermal and mechanical stress on the cutting edge, which lowers flank wear and extends service intervals. For production environments where consistent component quality and uptime matter, this insert helps maintain cycle times and reduces regrind or replacement frequency. The trigon geometry contributes to uniform load distribution, which supports repeatable performance under medium to robust cutting conditions.

Reliable chip control and improved surface integrity

Equipped with the FM5 chipbreaker and a 0° (negative) rake, the insert promotes secure chip formation when machining ductile, work‑hardening materials. Controlled chip segmentation minimises built‑up edge and reduces the risk of scratch marks on the workpiece, so a high‑quality surface finish is more readily achieved in fewer passes. The modest 0.4 mm corner radius balances edge strength and finish capability, providing resistance to edge chipping while enabling acceptable surface quality on internal and external turning operations.

Practical geometry and workshop compatibility

The Trigon 80° shape provides a positive compound of accessibility and strength for a range of turning tasks, including shoulder cuts and profiling where approach angles matter. The insert thickness and form correspond to common toolholder families, simplifying inventory management and tool changeover. Marked as a standard indexed insert, it offers straightforward seating and repeatability during index changes, supporting a dependable production rhythm with minimal operator adjustment.

Application advice and process reliability

This grade is optimised for rostfreier Stahl and is intended for users seeking a compromise between edge robustness and economical tool life. The coated WMP20S grade supports stable chip control across a wide set of stainless alloys, helping to avoid frequent interruptions for chip clearance. For new applications, begin with conservative cutting data and adjust speeds and feeds while monitoring edge condition; the insert’s design helps absorb process variability and contributes to predictable outcomes.

FAQ

What materials is this insert intended for?
The WNMG080404-FM5 WMP20S is specified for machining rostfreier Stahl and is formulated to support stable chip formation and edge life in such alloys.

Which chipformer does the insert use and what is its benefit?
The insert uses the FM5 chipbreaker, which encourages segmented, controllable chips and reduces the likelihood of built‑up edge when cutting ductile stainless materials.

What does the Trigon 80° shape mean for turning operations?
The Trigon 80° geometry provides a blend of accessibility and edge strength, making the insert versatile for shoulder turning and profiling while maintaining rigidity.

How large is the corner radius and how does it affect finish?
The corner radius is 0.4 mm; this radius increases edge strength to resist chipping while still enabling acceptable surface finish on a variety of turning tasks.

Is this a coated insert and what advantage does the coating provide?
Yes, the WMP20S belongs to the Tiger·tec Silver series; the coating enhances thermal and abrasive resistance, supporting longer tool life and consistent performance.
