WNMG080408-MS3 WSM30S turning insert — Trigon 80°, 0.8 mm radius (Walter Tools)

WNMG080408-MS3 WSM30S is a trigon turning insert designed for demanding turning tasks in stainless steels and heat-resistant alloys, combining a coated carbide grade with a dedicated chipbreaker for process stability

Tiger·tec Silver coating, grade WSM30S
Trigon 80° geometry for sturdy cutting
MS3 chipbreaker for reliable chip control
Suitable for stainless steels and superalloys

High-temperature stability for consistent performance

The Tiger·tec Silver coating combined with the WSM30S grade delivers enhanced heat resistance and wear protection, which stabilises the cutting edge during extended cycles. This coated carbide technology reduces flank wear and slows crater formation, resulting in longer tool life and fewer interruptions to production. For operations that generate elevated temperatures—such as machining stainless steels and superalloys—the thermal resilience of the grade supports predictable tool behaviour and consistent component tolerances.

Geometry engineered for secure cutting and chip control

The Trigon 80° shape and a corner radius of 0.8 mm provide a robust cutting edge capable of absorbing intermittent loads and heavier depths of cut. The negative 0° rake (designated negative) increases edge strength for roughing operations, while the MS3 chipbreaker is optimised to form manageable chips in materials that tend to produce long, stringy swarf. Together these design choices reduce the risk of built-up edge and improve surface finish stability, which supports higher material removal rates without compromising repeatability.

Application advantages for difficult-to-machine alloys

This indexable insert is intended for machining classes M and S according to ISO guidelines—specifically rostfreier Stahl (stainless steel) and heat-resistant superalloys and titanium where poor thermal conductivity and high cutting temperatures are typical. The combination of coating and chip control reduces thermal and mechanical stress at the cutting zone, which can translate into improved process reliability, fewer insert changes and reduced cycle-time variability on both conventional and CNC turning centres.

Practical handling and integration into production

The insert follows common WNMG seating and clamping standards and is suitable for toolholders configured for trigon 80° inserts, enabling straightforward integration into existing tool sets. The neutral to robust geometry supports a range of turning strategies from interrupted roughing to semi-finishing passes.

FAQ

What materials is this insert suitable for?
The WNMG080408-MS3 WSM30S insert from Walter Tools is designed for stainless steels (ISO group M) and heat-resistant superalloys / titanium (ISO group S), providing thermal resistance and edge stability for such materials.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating enhances wear resistance and heat tolerance of the insert, which helps maintain cutting-edge integrity and extends tool life during prolonged turning operations.

What role does the MS3 chipbreaker play?
The MS3 chipbreaker is engineered to control chip formation in ductile, difficult-to-machine alloys, promoting short, manageable chips and reducing the risk of swarf entanglement or built-up edge.

Is the Trigon 80° geometry suitable for roughing?
Yes, the Trigon 80° form combined with a 0.8 mm corner radius and negative 0° rake provides the strength required for roughing and intermittent cuts while still allowing for stable semi-finishing passes.

Can the insert be used with standard WNMG toolholders?
The insert conforms to the WNMG seating standard and is compatible with toolholders designed for trigon WNMG inserts; verify holder clamping and clearance for optimal performance.
