WNMG080404-MM5 WMP20G indexable insert, Tiger·tec Gold coating – Walter Tools

A compact WNMG080404-MM5 WMP20G indexable insert designed for turning stainless steels under medium to robust cutting conditions.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised MM5 chipbreaker for stable chips
• Trigon 80° form with 0.4 mm corner radius
• Negative 0° rake for robust turning performance

Longer tool life for stainless-steel turning

The combination of the Tiger·tec Gold coating and the WMP20G carbide composition provides improved wear resistance and reliable edge stability when working with stainless steel. The surface treatment reduces adhesive wear and supports higher cutting parameters compared with uncoated grades, which translates into longer tool life and fewer changeovers. For production environments the result is predictable performance and lower tool handling overhead.

Consistent chip control and secure cutting

The MM5 chipbreaker is configured to promote short, uniform chips and controlled evacuation in interrupted or continuous cuts. Together with the negative rake 0° geometry, this insert resists chipping at the cutting edge and minimises built-up edge formation, a common challenge with austenitic stainless grades. The outcome is greater process stability and fewer machining interruptions during serial turning tasks.

Geometry tailored for versatile turning operations

The Trigon 80° shape and 0.4 mm corner radius balance strength and form accuracy: the trigon profile offers positive engagement for general turning, while the modest corner radius supports finer surface finishes without sacrificing edge robustness. The insert thickness and profile suit a wide range of standard tool holders, enabling straightforward integration into existing turning setups for component production or repair work.

Productivity and process security in daily use

Adoption of this insert supports measurable productivity gains by reducing downtime for insert changes and by providing consistent results across batches. The design emphasises repeatability and a stable cutting edge, which benefits operators and process engineers aiming to maintain tolerances and surface quality while optimising cycle times. Allied to competent tooling advice, the solution supports efficient machining strategies in stainless-steel applications.

FAQ

What materials is this insert intended for?
The WNMG080404-MM5 WMP20G is intended primarily for stainless steel (ISO group M) machining where secure chip control and edge stability are required.

How does the Tiger·tec Gold coating help in production?
The Tiger·tec Gold coating on the WMP20G grade increases wear resistance and thermal stability, enabling higher cutting parameters and more consistent tool life in serial turning operations.

Which chipbreaker is fitted and what benefit does it provide?
The insert features the MM5 chipbreaker, designed to produce short, even chips and to improve evacuation, reducing the risk of chip entanglement in turning operations.

Is this insert compatible with standard tool holders?
The Trigon 80° geometry and standard WNMG form factor make the insert compatible with common turning tool holders; suitability should be confirmed against the holder catalogue for clamping and seat fit.

Can this insert be used for finishing and medium roughing?
Yes. The 0.4 mm corner radius and robust edge make the insert suitable for finishing and medium roughing, offering a balance between surface quality and edge strength.
