WNMG080416-MM5 WSM20S MM5 Wendeplatten - Walter Tools

High wear resistance from the Tiger·tec Silver coating combined with a robust Trigon 80° geometry and a 1.6 mm corner radius delivers secure chip control and long tool life when machining stainless steel and heat‑resistant superalloys. The combination of heat‑resistant coating and a stable cutting edge supports productive turning operations.

WNMG080416-MM5 WSM20S – Indexable turning insert, Trigon 80°, Tiger·tec Silver (Walter Tools)

The WNMG080416-MM5 WSM20S is an indexable turning insert engineered for heavy‑duty and difficult‑to‑machine materials, optimised for stainless steel and high‑temperature superalloys.

• Tiger·tec Silver coated carbide grade WSM20S
• Trigon 80° shape for heavy turning
• 0° negative rake for stable cuts
• 1.6 mm corner radius for extended life

Maximised performance for demanding materials

The Tiger·tec Silver coating and the WSM20S grade combine to provide high thermal stability and wear resistance during continuous cutting. For materials that tend to work‑harden or retain heat—such as stainless steel and other stainless alloys—the coated carbide substrate supports stable cutting edge behaviour and reduces the risk of built‑up edge. This results in fewer interruptions for tool changes and a more consistent component surface finish, translating directly into improved shop productivity.

Geometry that creates reliable process security

The Trigon 80° plate form and 0° negative rake deliver a geometry optimised for rigidity and vibration damping in interrupted and heavy turning. A corner radius of 1.6 mm increases edge strength, which reduces chipping in tough conditions and supports longer intervals between reprofiling. In practice, this geometry means more reliable cycle times and predictable tool life in series production, allowing process engineers to plan machining windows with confidence.

Coating and chip control explained for production

The coated carbide composition of this insert is designed to combine heat resistance with a robust substrate. The Tiger·tec Silver technology provides a multi‑layer protection that helps maintain the cutting edge at elevated temperatures, while the MM5 chipbreaker supports controlled chip formation in long, stringy materials. For operators less familiar with coatings: a high‑temperature stable coating delays abrasive and adhesive wear, which reduces rework and improves overall component quality.

Practical application and integration in the workshop

As an indexable insert, the component fits standard tool holders that accept WNMG‑style plates; the standardised geometry simplifies replacement and inventory management. The WSM20S grade is suitable where a compromise between toughness and temperature resistance is required—typical uses include turning operations on components containing austenitic stainless steels and certain superalloys. Selecting the correct holder and cutting parameters remains essential; machining partners benefit from a short trial cut to confirm optimal feed and speed for the specific workpiece material.

FAQ

What materials is this insert designed for?
The WNMG080416-MM5 WSM20S is designed primarily for stainless steel (ISO group M) and for heat‑resistant superalloys (ISO group S), providing a balance of heat resistance and edge stability.

What does the MM5 chipbreaker achieve?
MM5 is a chipbreaker geometry that supports controlled chip formation and evacuation, helping to avoid long, uncontrolled chips when machining tough alloys with the WSM20S grade.

How does the Tiger·tec Silver coating influence performance?
Tiger·tec Silver increases the thermal and wear resistance of the coated carbide, which helps to maintain a sharp, stable cutting edge under elevated temperatures and abrasive conditions.

Is the Trigon 80° shape suitable for heavy cuts?
Yes, the Trigon 80° form provides rigidity and strength at the cutting edge, making it well suited to heavy and interrupted turning tasks when combined with the 0° negative rake.

How should toolholders be selected for this insert?
Select a toolholder compatible with WNMG‑style inserts and ensure correct clamping torque and geometry alignment; the insert’s dimensions (size 08, thickness 04, 1.6 mm corner radius) should match the holder seat.
