WNMG080412-RM5 WMP30G Trigon 80° turning insert, Tiger‑tec Gold – Walter Tools

The WNMG080412-RM5 WMP30G is a Trigon 80° turning insert designed for robust finishing and medium-duty roughing of rostfreier Stahl, combining a negative relief geometry with a proven chipbreaker for consistent material removal

• Tiger‑tec Gold coating for extended tool life
• Optimised for rostfreier Stahl (ISO group M)
• Trigon 80° form for robust turning
• RM5 chipbreaker for reliable chip control

Longer production runs with predictable tool life

The Tiger‑tec Gold coating, together with the WMP30G carbide grade, provides a balance between wear resistance and edge stability that increases component throughput. Coated carbide reduces flank wear and helps maintain surface quality over extended cycles; this means fewer indexings and more uninterrupted machining time. For planners and buyers, the technical advantage translates into higher machine utilisation and lower tooling interventions per component lot.

Secure chip control for continuous operation

The RM5 chipbreaker is configured to promote short, controllable chips when machining rostfreier Stahl, reducing the risk of built‑up edge and improving evacuation from the cutting zone. Chip behaviour influences surface finish and tool life: stable chips protect the cutting edge and simplify downstream machining processes. In practice, this leads to fewer stoppages for clearing and a more predictable production rhythm on lathes and turn‑mill centres.

Geometry that supports robust turning and accuracy

The Trigon 80° form and negative 0° relief deliver a geometry that resists shock loads and supports stable cutting in interrupted cuts. A corner radius of 1.2 mm increases edge strength for tougher feeds while preserving dimensional control. These geometric choices reduce the chance of edge chipping during heavy engagement and contribute to consistent part tolerances across batches, which is essential for quality assurance in serial production.

Application focus and material compatibility

The grade is specifically tuned for ISO group M work — rostfreier Stahl — which tends to be tougher and to generate higher temperatures at the cutting edge. The combination of coated carbide and the selected chipbreaker helps to manage adhesion tendencies and thermal loads. For engineers assessing tool selection, the insert suits medium to robust conditions where repeatable surface finish and process security are required rather than ultrafine finishing at very low cutting pressures.

FAQ

Is this insert suitable for continuous turning of rostfreier Stahl?
The WNMG080412-RM5 WMP30G insert is designed for rostfreier Stahl and performs reliably in continuous turning when matched with appropriate feeds and coolant strategies.

What benefit does the Tiger‑tec Gold coating provide?
Tiger‑tec Gold on the WMP30G grade enhances wear resistance and edge stability, extending tool life and supporting consistent surface quality in stainless steel applications.

Which chipbreaker should be selected for mixed finishing and light roughing?
The RM5 chipbreaker included with this insert offers controlled chips for a range of cutting depths, making it suitable for both finishing and moderate roughing operations.

Can this insert handle interrupted cuts and heavier engagement?
Yes; the Trigon 80° geometry and negative relief improve resistance to shock loads, and the 1.2 mm corner radius increases edge robustness in intermittent cutting.

How does the geometry affect surface finish and dimensional accuracy?
The combined Trigon form and controlled chip formation support stable cutting conditions, which helps maintain repeatable surface finishes and tight dimensional tolerances across production batches.
