WNMG080404-FM5 WMP20G turning insert — Trigon 80°, 0.4 mm radius (Walter Tools)

A WNMG080404-FM5 WMP20G is a trigon 80° indexable turning insert designed for robust machining of rostfreier Stahl in medium to heavy cutting conditions.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised FM5 chipbreaker for rostfreier Stahl
• Trigon 80° form with 0.4 mm corner radius
• 0° negative rake for stable cutting performance

Durable coating and grade for demanding rostfreier Stahl work

The Tiger·tec Gold coating in combination with the WMP20G grade provides a wear-resistant, multi-layer surface that supports stable chip formation and consistent edge life when machining rostfreier Stahl. Coated carbide engineering reduces adhesion and builds-up edge tendency, so the cutting edge remains serviceable for longer periods under heat‑generating conditions. For production environments, this translates into fewer tool changes and improved process reliability without compromising surface quality.

Geometry engineered for chip control and edge strength

The Trigon 80° geometry and FM5 chipbreaker are balanced to deliver a repeatable cutting pattern and controlled chip flow in demanding operations. A 0.4 mm corner radius adds edge robustness, while the 0° negative rake strengthens the cutting edge against shock and vibration in heavier cuts or interrupted machining. Together these features help maintain a consistent cut depth and reduce the risk of edge chipping, resulting in predictable component tolerances and reduced rework.

Practical benefits for workshop productivity

As an indexable insert, the part offers quick edge renewal and straightforward handling on standard toolholders, improving up‑time and throughput. The combination of grade and geometry supports both semi‑finish and more robust turning tasks on rostfreier Stahl, delivering improved surface finish and process security. For engineers and supervisors, the main advantage is a lower total cost of ownership through longer tool‑life, fewer interventions and stable part quality under varying production loads.

Clear suitability and application guidance

This insert is specifically formulated for rostfreier Stahl machining and performs best under medium to robust conditions where heat and adhesion are primary concerns. The FM5 chipbreaker aids reliable chip evacuation and reduces the chance of material welding to the edge. For unfamiliar tool setups, matching the insert to the correct toolholder and machine parameters will ensure optimal results; specify the insert's designation when consulting tool selection charts or service teams.

FAQ

What materials is this insert suitable for?
The WNMG080404-FM5 WMP20G turning insert from Walter Tools is optimised for rostfreier Stahl and is intended for medium to robust cutting conditions where secure chip control is required.

What benefit does the FM5 chipbreaker provide?
The FM5 chipbreaker on this Walter Tools insert improves chip control and evacuation when machining rostfreier Stahl, reducing the likelihood of material adhesion and supporting a stable cutting process.

How does a 0° negative rake affect cutting performance?
A 0° negative rake increases edge strength and resistance to chipping, which is advantageous in tougher cuts or interrupted machining; it trades a small increase in cutting force for greater robustness and reliability.

Is this insert suitable for finishing operations?
Yes, the combination of Tiger·tec Gold coating and the WMP20G grade can achieve good surface quality; however, best results depend on machine stability and correct cutting parameters for rostfreier Stahl.

How is the insert indexed or replaced in the toolholder?
The insert is an indexable type; when one cutting edge is worn, the insert is rotated or replaced to present a fresh edge, minimising downtime and simplifying tool management.
