VCMT160408-RM4 VCMT160408-RM4 WSM10S — Indexable turning insert for stainless steel and superalloys (Walter Tools)

VCMT160408-RM4 WSM10S is a rhombic 35° indexable turning insert developed for reliable performance in demanding turning operations on stainless steel and heat‑resistant alloys.

• Tiger·tec Silver coating resists heat
• Optimised RM4 chipbreaker for stable chips
• Suitable for stainless steel and superalloys

Keep production running with reliable chip control

The insert’s RM4 chipbreaker is designed to promote a predictable chip form under interrupted and continuous turning, reducing the risk of built‑up edge and machined surface defects. Stable chip evacuation lowers rework rates and shortens cycle times, which improves overall productivity in serial production. For shops converting programmes from conventional grades, the RM4 geometry helps to maintain process stability without extensive parameter trials, enabling faster ramp‑up and fewer rejected parts.

Coating and grade engineered for tough materials

The combination of the WSM10S coated carbide grade and the Tiger·tec Silver technology targets the thermal and mechanical stresses typical of machining stainless steel and S‑group materials. The coating increases heat resistance and reduces adhesion at the cutting edge, which extends edge life and helps to maintain dimensional accuracy over longer tool life. For components where consistent surface finish and repeatability are essential, this coated grade reduces downtime for insert changes and supports cost‑effective, continuous operation.

Geometry that balances access, strength and finish

Featuring a Rhombus 35° cutting face with a 0.8 mm corner radius and a 7° clearance, the geometry is optimised for turning where a balance between cutting edge robustness and accessibility is required. The rhombic shape allows machining close to shoulders and in tight grooves, while the moderate corner radius supports edge strength for interrupted cuts. These characteristics contribute to a reliable surface finish and predictable tool wear, making the insert suitable for a wide range of external and light internal turning tasks.

Designed for shopfloor integration and consistent results

As an indexable insert from Walter Tools’ Tiger·tec Silver series, this solution integrates into standard toolholders and turning systems with minimal setup changes. The grade’s behaviour under higher temperatures and tendency for stable chip formation contribute to lower tooling consumption per part and reduced process variability. For production engineers focused on repeatable cycle times and quality, selecting this insert supports a measurable improvement in machining stability and part throughput.

FAQ

What materials is this insert suited for?
The VCMT160408‑RM4 WSM10S is designed primarily for stainless steel and heat‑resistant superalloys (ISO groups M and S), offering enhanced heat resistance and chip control for those materials.

How does the RM4 chipbreaker improve machining?
The RM4 chipbreaker on this insert promotes stable chip formation and evacuation, reducing built‑up edge and supporting continuous production with fewer interruptions.

What does the Tiger·tec Silver series provide?
Tiger·tec Silver coating improves thermal resistance and edge life; in the WSM10S grade this leads to more consistent cutting performance on demanding alloys.

Which geometrical features influence surface finish?
The Rhombus 35° shape, combined with a 0.8 mm corner radius and 7° clearance, balances edge strength and accessibility, helping to achieve a predictable surface finish and reduced vibration in many turning operations.

Can the insert be used in standard toolholders?
Yes, the insert is compatible with common indexable turning holders designed for VCMT‑type inserts, facilitating straightforward integration into existing turning systems.
