WNMG080412-RM5 WMP20G Turning Insert, Trigon 80°, Tiger‑tec Gold – Walter Tools

A WNMG080412-RM5 WMP20G indexable turning insert developed for robust machining of rostfreier Stahl under medium to demanding conditions

• Tiger‑tec Gold coated for extended tool life
• Optimised for rostfreier Stahl machining (M)
• Trigon 80° geometry with 1.2 mm corner radius
• Negative 0° rake for stable cutting performance

Reliable performance for challenging stainless applications

The combination of the WMP20G grade and Tiger‑tec Gold technology delivers a balance between wear resistance and toughness that is particularly valuable when machining rostfreier Stahl. The grade is a coated carbide designed to resist edge chipping and reduce built‑up edge, so the operator benefits from stable chip formation and longer effective tool life. For shops seeking predictable batch quality, this means fewer interruptions for insert changes and more consistent surface finishes over long cycles.

Geometry that promotes stability and surface integrity

The Trigon 80° form and 1.2 mm corner radius are chosen to combine good strength at the cutting edge with the ability to handle interrupted cuts often encountered in stainless operations. The negative 0° rake increases cutting edge robustness and reduces the tendency for the tool to dig in under heavy feed, which supports dimensional stability and lowers the risk of workpiece damage. Explained simply: the geometry trades a little cutting aggressiveness for reliable edge retention and improved part consistency.

Coating and chipcontrol for efficient production

The insert’s coating and the specified RM5 chipbreaker work together to control chip shape and evacuation when turning tough materials. Effective chip control shortens cycle times by preventing snarled chips and reduces secondary handling. The coated surface also decreases friction at the cutting zone, which can help to maintain cutting temperatures and reduce thermal load on the edge—this is especially relevant for rostfreier Stahl, which tends to generate higher heat during cutting.

Practical benefits for shop floor integration

Using this insert in appropriate toolholders and with tuned cutting parameters provides clear process advantages: steadier tool life, fewer surface defects and less downtime caused by edge failure. The insert’s design suits both continuous and moderately interrupted cuts, and its specification supports straightforward stocking: the grade, geometry and chipbreaker are commonly used in industrial turning applications, simplifying assortments and reordering.

FAQ

Which materials is this insert intended for?
The WNMG080412-RM5 WMP20G insert is specified for rostfreier Stahl (ISO group M) and performs well under medium to robust stainless steel cutting conditions thanks to the Tiger‑tec Gold coating.

What does the RM5 chipbreaker provide?
The RM5 chipbreaker offers controlled chip formation and evacuation for many turning operations, reducing chip snarling and aiding continuous production flow when using this turning insert.

How does the Trigon 80° geometry affect cutting?
Trigon 80° geometry concentrates strength at the cutting edge while allowing effective approach angles for turning; combined with the 1.2 mm corner radius it enhances edge robustness and part finish consistency.

Is this grade suitable for interrupted cuts?
Yes—because of the negative 0° rake and the coated carbide construction of the WMP20G grade, the insert tolerates moderate interruption and shock better than more fragile, high‑feed geometries.

What is the main benefit of the Tiger‑tec Gold series here?
Tiger‑tec Gold promotes balanced wear resistance and toughness, which helps to avoid premature chipping and maintain a stable cutting edge when machining rostfreier Stahl.
