WNMG080404-MM5 WSM20S indexable turning insert — Tiger·tec Silver coating for rostfreier Stahl and superalloys | Walter Tools

The WNMG080404-MM5 WSM20S is a Trigon 80° indexable turning insert designed for robust machining of rostfreier Stahl and heat-resistant superalloys, offering stable cutting performance in challenging conditions

• Tiger·tec Silver coating for heat resistance
• Trigon 80° geometry for robust turning
• MM5 chipbreaker for secure chip control
• 0° negative rake for stable cutting
• 0.4 mm nose radius for versatile finishing

Consistent cutting performance under thermal stress

The Tiger·tec Silver coating combined with the WSM20S grade delivers a balance of hardness and thermal stability that reduces wear when machining rostfreier Stahl and high-temperature alloys. The coated carbide composition improves resistance to abrasion and adhesion, which mitigates built-up edge and extends edge life. For production environments where heat generation and material toughness cause frequent tool changes, this insert supports longer intervals between indexings and a more predictable process window.

Improved chip control and surface quality for reliable production

A dedicated MM5 chipbreaker and Trigon 80° profile promote controlled chip formation and evacuation, lowering the risk of entanglement or re-cutting. The 0° negative rake increases insert strength under heavy cuts, while the 0.4 mm nose radius offers a compromise between finish quality and tool robustness. These design choices result in reduced vibration, more uniform cutting forces and an improved surface finish with fewer secondary operations, which supports higher first-pass yields in series production.

Seamless integration and process security for workshop efficiency

Designed to fit standard toolholders for this insert family, the component conforms to tolerance class M, ensuring reproducible seating and stable clamping. The series’ focus on broad material coverage (S / M) means flexible application across parts made from rostfreier Stahl, titanium and nickel-based superalloys depending on machining strategy. Together with Walter Tools’ development emphasis on process stability, this insert fosters consistent cycle times and dependable component quality in medium- to high-duty turning operations.
