WNMG080408‑MM5 WSM20S indexable turning insert — Trigon 80° with MM5 chipbreaker (Walter Tools)

The WNMG080408‑MM5 WSM20S is an indexable turning insert designed for heavy‑duty machining of rostfreier Stahl and heat‑resistant superalloys, combining a coated carbide grade with a strong cutting geometry.

• Tiger·tec Silver coating for heat resistance
• Trigon 80° shape for a stable cutting edge
• MM5 chipbreaker for secure chip formation
• Optimised for rostfreier Stahl and superalloys

Consistent productivity on rostfreier Stahl and superalloys

The Tiger·tec Silver coating in the WSM20S grade is formulated to withstand the thermal and mechanical stresses typical of rostfreier Stahl and high‑temperature alloys. This results in stable chip formation and reduced risk of built‑up edge, which directly contributes to longer tool life and fewer unscheduled insert changes. For production environments where repeatability matters, the combination of a thermally resilient coating and a robust base microstructure enables higher cutting parameters with predictable surface finish and dimensional stability.

Geometry that balances strength and surface finish

The Trigon 80° form delivers a reinforced cutting edge that tolerates interrupted cuts and heavier depths of cut, while the 0.8 mm corner radius provides a compromise between edge strength and achievable surface quality. The 0° (negative) relief angle increases insert support in the pocket and reduces the likelihood of edge chipping under heavy loads. Together these geometric choices mean fewer tool‑related interruptions and an improved overall machining economy for demanding turning operations.

Chip control and process security through MM5 design

The MM5 chipbreaker is engineered to produce short, controllable chips when turning ductile and work‑hardening materials. For rostfreier Stahl and superalloys, predictable chip form reduces the risk of surface damage and minimises rework. Integrating this chipbreaker with the coated substrate of Tiger·tec Silver helps maintain a stable cutting edge, allowing for higher metal removal rates with consistent results and improved operator safety.

Practical integration and tolerance assurance

The insert designation WNMG080408‑MM5 WSM20S reflects a commonly available WNMG format that is compatible with standard toolholders for indexable turning. The product is delivered in a tolerance class M, ensuring interchangeability and repeatable seating in the tool pocket. For shops seeking a single‑grade solution across a range of rostfreier Stahl parts and selected high‑temperature alloys, this insert reduces inventory complexity while maintaining process reliability.
