VNMG160404-FM5 WSM20S Drehwendeschneidplatte, Tiger·tec Silver – robust geometry and coated carbide for rostfreier Stahl and superalloys | Walter Tools

The VNMG160404-FM5 WSM20S is a rhombic 35° indexable insert engineered for turning rostfreier Stahl and heat‑resistant superalloys in demanding industrial machining environments.

• Tiger·tec Silver coated carbide grade WSM20S
• Optimised for rostfreier Stahl and superalloys
• Rhombic 35° form with 0.4 mm corner radius
• FM5 chipbreaker for consistent chip control

High reliability when machining demanding alloys

The combination of the Tiger·tec Silver coating and the WSM20S grade delivers a coated carbide solution adapted to the thermal and mechanical stresses common in machining rostfreier Stahl and nickel‑based alloys. The coating technology supports stable edge retention and reduced adhesion tendencies that otherwise cause built‑up edge on tough materials. Where heat generation and poor thermal conductivity make cutting conditions challenging, this insert's materials and treatment help maintain a repeatable cutting action and consistent surface quality, reducing the need for frequent tool changes and unscheduled rework.

Geometry that prioritises process security and uptime

A rhombic 35° geometry with a 0.4 mm corner radius and 0° (negative) rake provides a robust cutting edge that tolerates higher cutting forces and offers predictable wear behaviour. The FM5 chipbreaker is designed to produce controlled, segmented chips at the typical feeds for finishing and medium cutting, which minimises risk of chip entanglement and supports uninterrupted automatic machining. These geometric choices translate into fewer interrupted cycles, longer steady‑state tool life and better overall line efficiency in serial production.

Practical advantages and clear application domains

This indexable insert is targeted at production and jobbing shops requiring high process security when turning rostfreier Stahl and heat‑resistant superalloys. The insert's specifications make it suitable for operations where repeatability and surface integrity are essential. For customers less familiar with technical terms: coated carbide means a hard, wear‑resistant substrate with a protective coating that reduces friction and heat at the cutting zone; the chipbreaker shapes and breaks the chips to avoid long, stringy swarf. Such features support predictable machine cycles and simpler downstream handling, contributing to measurable productivity improvements.

Suitable users and integration into workflows

The insert is a practical choice for CNC turning centres in aerospace, energy and specialist engineering where rostfreier Stahl and superalloys are common. It integrates into standard toolholders that accept the VNMG form and can be used across a range of turning strategies from light finishing to more aggressive semi‑finishing, provided cutting data are adjusted to the component material and rigidity of the setup. For engineers seeking to optimise cycle time and surface finish, the combination of grade and geometry offers a reliable base to develop cut‑data that balance speed and tool life.
