VCMT160402-FM4 WMP20G — turning insert by Walter Tools (for rostfreier Stahl)

VCMT160402-FM4 WMP20G is a coated turning insert designed for reliable machining of rostfreier Stahl under medium to robust conditions.

• Tiger·tec Gold coated grade WMP20G
• Optimised FM4 chipbreaker
• Rhombus 35° geometry, 0.2 mm radius
• Designed for rostfreier Stahl machining

Maximise process reliability with a wear-resistant grade

The combination of the Tiger·tec Gold coating and the WMP20G carbide grade delivers enhanced resistance to thermal and abrasive wear, which translates into longer edge life and fewer tool changes. For applications in rostfreier Stahl, which tend to cause high heat and work-hardening, this coated grade supports stable chip formation and reduces the risk of built-up edge. The insert’s engineered surface treatment improves heat dissipation and reduces friction, supporting consistent performance in serial production and lowering overall machining costs through extended tool life.

Controlled chip flow and repeatable surface quality

The FM4 chipbreaker geometry is tuned to produce short, predictable chips in a wide range of turning operations, reducing swarf handling issues and protecting toolpaths. The Rhombus 35° shape and the 0.2 mm corner radius provide a balance of strength and accessibility, permitting close-to-shoulder cuts and fine finishing where required. These features together contribute to predictable cutting forces, which help maintain machine stability and achieve reproducible surface finishes on rostfreier Stahl components with fewer rework cycles.

Practical benefits for workshop and production planning

As a compact, indexable insert, this solution supports quick index changes and economical reuse of the cutting edges, improving uptime and reducing inventory complexity. The insert designation VCMT160402-FM4 WMP20G signals a standard geometry compatible with a wide range of turning toolholders, simplifying tooling decisions. Process engineers benefit from reduced setup time thanks to reliable cutting edge stability, while operators appreciate fewer interruptions for tool changes—an efficient choice for repetitive and mixed-batch production.

FAQ

What materials is this insert suited for?
The insert is specified for machining rostfreier Stahl; the WMP20G grade and Tiger·tec Gold coating are optimised for the demands of that material class.

How does the FM4 chipbreaker affect performance?
The FM4 chipbreaker produces short, controlled chips that simplify swarf control and help maintain consistent cutting forces for repeatable results.

Can the insert be used for finishing and roughing?
Yes; the Rhombus 35° geometry with a 0.2 mm corner radius allows for fine finishing and light profiling, while the coated grade supports moderate roughing in rostfreier Stahl under appropriate cutting parameters.

Is the insert compatible with standard toolholders?
The VCMT geometry is a widely used indexable standard and fits common turning toolholders designed for Rhombus 35° inserts; verify holder compatibility with the toolholder supplier.
