VCMT160402-FM4 WSM20S indexable turning insert – Walter Tools, Tiger·tec Silver, FM4 chipbreaker

VCMT160402-FM4 WSM20S is an indexable turning insert designed for stable performance in stainless steels and heat-resistant superalloys, offering a balanced geometry for versatile external turning.

• Tiger·tec Silver coating for extended tool life
• Suited to stainless steels and superalloys
• Rhombic 35° geometry for versatile turning
• 7° clearance with 0.2 mm corner radius

Consistent machining in tough alloys increases uptime

The WSM20S grade, part of the Tiger·tec Silver series, is formulated to resist the high cutting temperatures and adhesive wear typical of stainless steels and superalloys. That resistance leads to a stable cutting edge and prolonged tool life, which in turn reduces interruptive tool changes and supports predictable batch planning. For operations where secure chip formation matters, the coated carbide composition helps maintain performance across longer cycles, translating directly into fewer stoppages and more efficient machine utilisation.

Geometry and chip control deliver repeatable surface quality

The rhombic 35° geometry combined with the FM4 chipbreaker and a 0.2 mm corner radius provides a balance between versatility and surface integrity. The acute geometry supports both light finishing cuts and medium-depth turning passes while the chipbreaker is optimised to shape and evacuate chips reliably in demanding alloys. A 7° clearance reduces rubbing and heat at the flank, improving the consistency of the finished component. These design choices contribute to measurable gains in productivity and a reduction in rework, especially when processing materials that tend to work-harden.

Practical advantages for workshop planning and tool management

Where cycle time and predictable consumable behaviour influence cost-efficiency, the combination of coating, grade and geometry offers tangible benefits: longer intervals between index changes, stable dimensional control and consistent surface finishes. The insert’s designation indicates compatibility with standard toolholders that accept the VCMT form, enabling straightforward integration into existing toolsets. For shops seeking to optimise throughput when machining stainless steels or high-temperature alloys, the grade’s engineered balance of toughness and wear resistance supports more productive machining with lower process variation.

FAQ

What materials is this insert intended for?
The VCMT160402-FM4 WSM20S is specified for stainless steels (ISO group M) and for heat-resistant superalloys and titanium (ISO group S), offering a carbide grade and coating suited to those challenges.

How does the Tiger·tec Silver coating benefit performance?
Tiger·tec Silver on the WSM20S grade improves wear resistance and thermal stability, which helps maintain a stable cutting edge and extends tool life when machining demanding alloys.

What role does the FM4 chipbreaker play?
The FM4 chipbreaker is engineered to control chip shape and evacuation during turning, reducing the risk of built-up edge and supporting consistent surface finish on long runs.

Is the insert suitable for finishing operations?
With its rhombic 35° geometry and 0.2 mm corner radius, the insert is appropriate for a range of turning tasks including light finishing cuts where surface quality and dimensional repeatability are required.

Which toolholders accept this insert form?
The VCMT form is a standard indexable insert shape; matching VCMT toolholders that accept the 35° rhombic insert are compatible with this insert designation.
