VCMT160408-FM4 WSM20S Turning indexable insert — Tiger·tec Silver, FM4 chipbreaker (Walter Tools)

VCMT160408-FM4 WSM20S is a turning indexable insert designed for hard-to-machine materials, offering stable cutting performance in demanding turning operations.

• Tiger·tec Silver coating for tough materials
• Optimised FM4 chipbreaker for stable chips
• Rhombus 35° form with 7° clearance
• Suitable for rostfreier Stahl and superalloys

Maximise throughput on difficult-to-machine alloys

The combination of the Tiger·tec Silver series and the WSM20S grade delivers a coating and substrate system optimised for temperature resistance and edge stability. This insert supports machining of the ISO material groups M and S, which include rostfreier Stahl and heat-resistant superalloys; the result is improved cycle times and fewer unexpected interruptions. The upgraded grade aims to maintain cutting-edge integrity under thermal load, reducing the frequency of insert changes and contributing to measurable productivity gains.

Consistent component quality through precise geometry

The Rhombus 35° form and 7° clearance angle create a controlled cutting geometry that helps deliver repeatable surface finish and dimensional consistency. A 0.8 mm corner radius balances edge strength and finish capability, making it suitable for both roughing and semi-finishing passes where surface quality is important. The insert’s tolerance class M and standard format ensure predictable seating in compatible toolholders, simplifying tool set-up and inspection routines.

Stable chip control and reduced process risk

Equipped with the FM4 chipbreaker, the insert promotes consistent chip formation across varied cutting conditions, which in turn lowers the risk of built-up edge and tool-induced vibrations. The chipbreaker design facilitates short, controllable chips during interrupted or continuous cuts, improving swarf evacuation and protecting the workpiece surface. For shops seeking to reduce rework and downtime, this combination of chip control and coating technology supports a safer, more stable turning process.

Easy integration and dependable series performance

The insert is part of the Tiger·tec Silver series, providing a well-documented performance envelope for planning cutting data and lifecycle expectations. Identified by form code VCMT160408-FM4, size 16, and thickness 04, it fits industry-standard Rhombus 35° pockets and is manufactured to a consistent tolerance class. Implementing this insert into existing tooling systems requires minimal adaptation while offering the benefit of Walter Tools’ engineering for reliable repeatability in production environments.
