WNMG080408-NMT WSM20S indexable turning insert — Trigon 80° form, Tiger·tec Silver coating (Walter Tools)

A WNMG080408-NMT WSM20S indexable insert engineered for demanding turning of rostfreier Stahl and heat-resistant alloys, offering stable cutting edges and optimised chip formation

• Tiger·tec Silver coating for high wear resistance
• Trigon 80° form with 0.8 mm corner radius
• Negative 0° rake suited to interrupted cuts
• Optimised for rostfreier Stahl and superalloys

Consistent performance for demanding materials

The WNMG080408-NMT WSM20S is supplied in a coated carbide grade developed under the Tiger·tec Silver technology, which combines a wear-resistant coating with a substrate engineered for edge stability. This combination reduces flank wear and resists build-up on the cutting edge when machining rostfreier Stahl (ISO M) and materials in group S (heat-resistant superalloys and titanium). The technical design ensures stable chip formation and extended tool life, which supports predictable cycle times and fewer insert changes in production environments.

Geometry and chip control that improve process reliability

The Trigon 80° plate form together with the 0.8 mm corner radius and the NMT chipbreaker are coordinated to deliver robust performance in medium- to heavy-duty turning operations. The negative 0° rake increases edge strength and is advantageous for interrupted or unstable cuts, while the chipbreaker design promotes short, controlled chips that evacuate reliably from the cut. These geometric choices enable the insert to be used for both roughing and mixed finishing tasks where edge security and repeatability are priorities.

Application benefits and operational clarity

Plate size 08 and thickness 04 identify a compact insert format that fits many standard indexable holders, permitting straightforward integration into existing tooling systems. The WSM20S grade is optimised for materials that generate heat and tend to work-harden, so machining parameters can be adjusted toward productivity without compromising surface integrity. The result is a balance of productivity and process safety: fewer interruptions for tool changes and consistent surface quality across batches. Technical compatibility with common turning toolholders is expected, and insert seating tolerances adhere to industrial norms to support secure clamping and repeatable indexing.

FAQ

What materials is this insert designed to machine?
The insert is specified for machining rostfreier Stahl (ISO M) and materials in the ISO S group such as superalloys and titanium; the WSM20S grade is optimised for these applications.

Does the geometry suit interrupted cuts or heavy cuts?
Yes, the negative 0° rake and the Trigon 80° form increase edge strength, making the insert appropriate for interrupted and heavier machining operations.

How does the Tiger·tec Silver coating contribute to performance?
The Tiger·tec Silver coating combines wear resistance with a substrate tuned for edge stability, which reduces wear rates and supports consistent surface finish when turning demanding materials.

Are chip control and evacuation improved with this insert?
The NMT chipbreaker and the 0.8 mm corner radius promote short, controlled chips and reliable evacuation, which helps to maintain stable cutting conditions.

What insert dimensions are indicated by the designation 080408?
The designation reflects the insert format: plate size 08 and plate thickness 04, with a corner radius of 0.8 mm and Trigon 80° geometry as specified.
