VBMT160412-FM6 WSM20S turning insert for stainless steel and superalloys — Walter Tools

The VBMT160412-FM6 WSM20S is a rhombic 35° turning insert designed for high demands in the machining of stainless steel and heat-resistant superalloys, offering a balance of edge stability and consistent chip control.

• Tiger·tec Silver coated grade WSM20S
• FM6 chipbreaker for secure chip control
• Rhombic 35° geometry for versatile turning
• 1.2 mm corner radius with 5° clearance

Consistent cutting performance with a coated grade

The combination of the Tiger·tec Silver coating and the WSM20S carbide substrate delivers improved wear resistance and thermal stability when machining demanding materials. Coating technology reduces flank wear and supports a stable cutting edge, which in turn enables longer tool life and fewer tool changes during production. The grade is specifically developed for stainless steel (ISO group M) and for heat-resistant superalloys and titanium (ISO group S), so process planners can rely on a single insert type for hard-to-machine workpieces without compromising component quality.

Secure chip control that protects the tool and surface

The FM6 chipbreaker geometry ensures defined chip formation under a variety of cutting conditions, reducing the risk of built-up edge and erratic chips that interrupt production. Stable chip evacuation contributes directly to an improved surface finish and reduces secondary operations. In practical terms, the chip control translates into higher first-pass quality and less machine downtime, delivering a measurable benefit to cycle-time-driven production environments.

Geometry engineered for versatile turning tasks

The rhombic 35° insert shape offers flexibility across finishing and semi-finishing passes, while the 1.2 mm corner radius provides a compromise between edge strength and fine surface quality. A 5° clearance angle supports effective cutting engagement and helps avoid rubbing on the flank, especially in interrupted cuts or when working with tough alloys. The compact VBMT format is well suited to a wide range of toolholders, allowing quick integration into existing tool systems without elaborate retooling.

Productivity and process stability for series production

Adopting this insert supports a predictable tool life and repeatable results, which are crucial for high-volume or regulated manufacturing. The material compatibility and coating selection reduce the frequency of requalification and the need for emergency tool changes, improving overall equipment effectiveness. Backed by the Walter Tools reputation, the insert supports a productive machining strategy where consistent surface quality and secure chip control are prioritised.

FAQ

What materials is this insert suited for?
The VBMT160412-FM6 WSM20S insert by Walter Tools is optimised for stainless steel (ISO group M) and for heat-resistant superalloys and titanium (ISO group S), offering secure chip control and thermal resistance.

Which chipbreaker should be selected for mixed cutting tasks?
The FM6 chipbreaker fitted to this insert is designed for reliable chip breaking across a range of feeds and depths, making it suitable for many finishing and semi-finishing turning operations.

How does the Tiger·tec Silver coating affect performance?
The Tiger·tec Silver coating improves wear resistance and heat management, supporting longer tool life and more consistent cutting-edge behaviour when machining demanding alloys.

Is the rhombic 35° geometry suitable for finishing passes?
Yes. The rhombic 35° geometry combined with a 1.2 mm corner radius supports fine surface finishes while maintaining sufficient edge strength for interrupted cuts.

Can this insert be used in standard VBMT toolholders?
The VBMT format is compatible with standard VBMT toolholders; correct seat and clamping should be verified to ensure repeatable positioning and optimal cutting results.
