WNMG080412-MU5 WMP20G — Trigon 80° indexable turning insert, Tiger‑tec Gold, for rostfreier Stahl (Walter Tools)

The WNMG080412-MU5 WMP20G is a Trigon 80° indexable turning insert designed for turning rostfreier Stahl under medium to robust cutting conditions, combining a coated carbide grade with a dedicated chipbreaker for reliable swarf control

• Tiger‑tec Gold grade for high wear resistance
• MU5 chipbreaker for stable chip formation
• Trigon 80° geometry for secure clamping
• 0° negative rake for robust cutting performance

Reliable chip control for high‑temperature materials

The Tiger‑tec Gold WMP20G grade is engineered to handle the typical challenges of rostfreier Stahl, including high ductility and thermal sensitivity. With a specialised MU5 chipbreaker, the insert promotes predictable chip formation and reduced risk of built‑up edge, which translates into fewer interruptions and more consistent cycle times. The combination of the coated carbide grade and the chipbreaker supports stable cutting forces, enhancing process reliability in both continuous and intermittent turning operations.

Geometry that improves tool life and surface quality

A Trigon 80° shape and a 1.2 mm corner radius deliver a balance between strength and surface finish. The trigon form provides three effective cutting corners per insert, while the moderate corner radius reduces local stress at the cutting edge, helping to extend service life during tougher cuts. The insert’s 0° negative rake increases edge robustness, making the geometry suited to operations where moderate to heavy engagement is required without sacrificing dimensional stability.

Practical benefits for workshop productivity

This insert’s geometry and grade are optimised for predictable performance and straightforward tool management. The standard WNMG form simplifies toolholder selection and indexing, enabling quick turnover on multi‑shift production lines. Thanks to the Tiger‑tec Gold technology, wear resistance is improved, which reduces frequency of tool changes and contributes to steady output quality. The product from Walter Tools supports process security and consistent surface results, making it a practical choice for shops machining rostfreier Stahl.

FAQ

What materials is this insert suitable for?
The WNMG080412-MU5 WMP20G insert is specified for rostfreier Stahl; the Tiger‑tec Gold grade supports secure chip formation and stable cutting when working these materials.

How does the MU5 chipbreaker affect machining?
The MU5 chipbreaker on this Walter Tools insert promotes shorter, consistent chips and reduces the likelihood of built‑up edge, improving surface consistency and process reliability.

Why choose a Trigon 80° geometry for turning?
Trigon 80° geometry offers three usable cutting corners per insert and a secure clamping interface; combined with a 1.2 mm corner radius, it balances edge strength and surface finish for robust operations.

What does a 0° negative rake mean in practical terms?
A 0° negative rake increases the edge’s mechanical strength and resistance to thermo‑mechanical loads, making the insert more tolerant of interrupted cuts and heavier engagements.

Is the WMP20G grade coated and what benefit does that provide?
Yes — WMP20G is a Tiger‑tec Gold coated carbide grade; the coating improves wear resistance and enhances tool life when machining rostfreier Stahl.
