VCGT160408-FM2 WSM20S | Indexable turning insert, FM2 chipbreaker (for stainless steels & superalloys) — Walter Tools

VCGT160408-FM2 WSM20S is a coated indexable turning insert designed to provide secure chip control and reliable edge life when machining demanding materials such as stainless steels and heat‑resistant superalloys

• Tiger·tec Silver coated grade WSM20S
• FM2 chipbreaker for stable chip control
• Rhombic 35° geometry for versatile turning
• 0.8 mm corner radius, 7° clearance angle

Consistent performance for demanding materials

The VCGT160408-FM2 WSM20S insert combines a coated carbide base with the Tiger·tec Silver technology to address difficulties typical of ISO group M and S materials. The grade WSM20S is specified for stainless steels (M) and superalloys / titanium (S), where toughness and heat build‑up challenge edge life. By using a specialised coating and substrate pairing, the insert supports steady chip formation and reduces the risk of built‑up edge, enabling more predictable process windows in production turning operations.

Geometry engineered for controllable chips and repeatable quality

The insert’s FM2 chipbreaker and Rhombus 35° shape are engineered to create defined chip segments and lower cutting forces on many turning profiles. The combination of a 0.8 mm corner radius with a 7° clearance angle balances edge strength and cutting access: the radius improves resistance to edge chipping while the relief angle assists in chip flow and surface finish. These geometric choices translate into fewer interruptions, consistent tolerances and improved surface integrity when replacing inserts in multi‑pass turning cycles.

Coating and grade advantages that extend tool life

The Tiger·tec Silver coating technology provides enhanced thermal stability and wear resistance without sacrificing toughness. In practice, the WSM20S coated grade supports secure edge retention against the adhesive and abrasive wear mechanisms common in stainless steels and high‑temperature alloys. The result is a reliable cutting edge that preserves dimensional accuracy for longer intervals between indexings, contributing to lower process variability and improved overall productivity on CNC turning centres.

Integration into tooling systems and process support

With a standard Rhombus 35° form and the designation VCGT160408-FM2, the insert fits common ISO toolholders for external turning and profiling. The tolerance class G and established grade mean straightforward tooling choice and repeatable seating during indexable changes. For tailored cutting parameters, Metav Werkzeuge’s application engineers can advise on feed, speed and coolant strategies to match the material and machine capabilities, helping to translate the insert’s technical benefits into measurable production gains

FAQ

What materials is this insert suitable for?
The VCGT160408-FM2 WSM20S insert (Walter Tools indexable turning insert, SKU VCGT160408-FM2-WSM20S-WALTER) is specified for ISO group M (stainless steels) and S (heat‑resistant superalloys and titanium), offering a balance of wear resistance and edge stability for those materials.

How does the FM2 chipbreaker affect machining?
The FM2 chipbreaker on this insert promotes controlled chip formation and evacuation; in the VCGT160408-FM2 WSM20S configuration it helps to reduce stringing and supports consistent surface quality during turning operations.

Which geometry benefits should be expected for finish and roughing passes?
The Rhombus 35° geometry combined with a 0.8 mm corner radius delivers enhanced edge strength for light roughing and finishing, while the 35° form offers versatility across a range of turning profiles for the Walter Tools insert.

Is the insert compatible with standard toolholders?
Yes, the VCGT160408-FM2 designation follows common ISO insert standards and is compatible with corresponding holders for rhombic 35° indexable inserts; tolerance class G ensures consistent seating and repeatability.

What does the Tiger·tec Silver grade deliver in daily production?
The Tiger·tec Silver coating used on the WSM20S grade provides thermal and wear benefits that support longer edge life and more predictable process stability when machining demanding materials, reducing tool change frequency and process variation.
