WNMG080408-RM5 WSM30S — indexable turning insert, Tiger·tec Silver, for stainless steels and superalloys — Walter Tools

WNMG080408-RM5 WSM30S is a Trigon 80° insert optimised for machining high-strength and heat-resistant materials, providing a reliable balance of edge stability and chip control.

• Tiger·tec Silver grade WSM30S
• Optimised RM5 chipbreaker
• Trigon 80° geometry, 0.8 corner radius
• Suitable for stainless steels and superalloys

High-performance grade for demanding components

The WSM30S cutting grade, part of the Tiger·tec Silver family, is engineered for tough-to-machine alloys. Its coated cemented carbide composition improves wear resistance and thermal stability, which reduces the risk of premature flank wear under elevated temperatures. This translated into predictable tool life and fewer in-process interruptions when turning materials that tend to work-harden or form built-up edges. For production environments where component consistency matters, the graded coating technology supports longer runs and more reliable cycle times.

Geometry that improves chip control and surface integrity

The insert’s RM5 chipbreaker and Trigon 80° form combine to manage chip flow and reduce contact time at the cutting edge, which helps to avoid entanglement and ensures repeatable surface finishes. The 0.8 corner radius strengthens the cutting edge for heavy engagement, while the 0° (negative) clearance geometry provides rigidity in robust toolholder systems. Together, these features reduce vibrations and support stable cutting conditions, resulting in fewer reworks and improved process throughput for shops working with stainless steels and nickel-based alloys.

Process security and practical application notes

Tolerance class M and the material designation S / M indicate suitability for stainless steels (M) and heat-resistant superalloys or titanium (S). The combination of a robust chipbreaker and the Tiger·tec Silver coating assists with controlled chip formation, which is particularly important when machining components that are prone to stringing or galling. In practice, select the insert geometry and cutting parameters with an emphasis on chip evacuation and coolant strategy to exploit the insert’s strengths; when correctly applied, the indexable insert supports both roughing passes with stable edge life and finishing passes that preserve surface quality.

FAQ

What materials is this insert best suited for?
This indexable turning insert in grade WSM30S is designed for stainless steels (M) and heat-resistant superalloys or titanium (S), offering enhanced thermal stability for those groups.

How does the RM5 chipbreaker affect machining?
The RM5 geometry promotes reliable chip control and reduced tool engagement, which improves surface quality and reduces the risk of chip-related interruptions when machining demanding alloys.

Is the Trigon 80° form suitable for heavy-duty turning?
Yes — the Trigon 80° shape combined with a 0.8 corner radius provides edge strength and stability for heavier cuts while maintaining the option for fine finishes.

Which tolerance class applies and what does it mean?
Tolerance class M denotes the manufacturing precision of the insert; it supports consistent seating and repeatable performance in suitably matched toolholders.

Can this insert be used for finishing passes?
When cutting parameters and toolholder rigidity are appropriately adjusted, the combination of the Tiger·tec Silver coating and the RM5 chipbreaker enables both productive roughing and quality finishing passes.
