WNMG080408-NRS WSM30S trigon turning insert — Tiger·tec Silver, for rostfreier Stahl (Walter Tools)

The WNMG080408-NRS WSM30S is a trigon 80° turning indexable insert designed for heavy-duty and high-temperature machining of rostfreier Stahl and heat‑resistant alloys.

• Tiger·tec Silver coating for wear resistance
• Optimised NRS chipbreaker for secure chip control
• Trigon 80° geometry for sturdy cutting edges
• Suitable for rostfreier Stahl and superalloys

High-temperature stability that keeps production running

The Tiger·tec Silver coating and the underlying coated carbide substrate provide pronounced wear resistance at elevated cutting temperatures, which translates to longer tool life and fewer interruptions on the shop floor. For materials that are difficult to machine, such as rostfreier Stahl and nickel‑based alloys, thermal stability reduces the tendency for edge breakdown and built‑up edge formation, improving process consistency. This focused durability supports higher productivity by allowing secure cutting parameters with predictable performance.

Consistent chip control and reduced rework

The insert’s NRS chipbreaker is engineered to control chip form across a range of feeds and depths of cut, lowering the risk of entanglement and surface damage. Stable chip evacuation reduces cycle variability and lessens the need for manual intervention, which benefits both single‑piece flows and batch production. With a reliable chip behaviour, downstream processes see fewer defects and rework rates decline, contributing to more efficient use of machine time and personnel.

Geometry that enhances edge security and rigidity

The Trigon 80° contour combined with a 0° negative rake (0° negative) yields a robust cutting edge suited to interrupted cuts and heavy radial engagement. The relatively large corner radius (0.8 mm) promotes edge strength and supports consistent radial load distribution, which is particularly valuable when machining tough alloys where edge chipping is a concern. These geometric choices prioritise process reliability and support higher metal removal rates while maintaining surface integrity.

Practical application guidance for integration

Designed for standard WNMG toolholders, this insert is straightforward to specify and replace in conventional turning setups. The WSM30S grade is tuned to balance toughness and hot hardness, making it suitable for operations where thermal loads and material toughness are limiting factors. When selecting cutting parameters, favour moderate cutting speeds with increased feed to maintain stable chip breaking; trial cuts will confirm the optimum settings for each component programme. If a different edge form or smaller radius is required, match the insert geometry to the toolholder and cycle requirements to ensure compatibility.

FAQ

What materials is this insert best suited for?
The WNMG080408-NRS WSM30S is designed primarily for rostfreier Stahl and for heat‑resistant superalloys and titanium, offering stability under high thermal stress.

How does the NRS chipbreaker affect machining?
The NRS chipbreaker promotes manageable chip forms across typical feeds and depths, improving evacuations and reducing the chance of surface blemishes or tool interference.

Is the insert compatible with standard WNMG toolholders?
Yes, the geometry matches standard WNMG toolholders; ensure correct clamping and clearance angles for secure operation.

Why choose Tiger·tec Silver for demanding turning tasks?
Tiger·tec Silver provides improved thermal resistance and wear control compared with uncoated grades, which supports extended edge life in tough cutting conditions.

What corner radius is available on this SKU and what is its benefit?
This SKU features a 0.8 mm corner radius, which increases edge robustness and reduces chipping risk during interrupted cuts.
