VCMT160404-FM4 WSM30S Turning Indexable Insert — Tiger·tec Silver, for stainless steel and superalloys — Walter Tools

VCMT160404-FM4 WSM30S is a coated turning insert designed for demanding applications in stainless steel and heat-resistant alloys, offering stable cutting edges and controlled chip formation

• Tiger·tec Silver coated grade WSM30S
• Rhombic 35° insert form
• 0.4 mm corner radius for fine finishes
• 7° relief angle for secure engagement
• FM4 chipbreaker for reliable chip control

Stable chip control and longer tool life for demanding materials

The combination of the WSM30S grade and the FM4 chipbreaker is engineered to improve chip control and reduce edge wear when machining stainless steel or high-temperature alloys. The coated carbide composition provides thermal and mechanical resistance, which supports stable cutting conditions and reduces the risk of built-up edge. For production environments where consistency matters, this geometry limits unexpected interruptions caused by poor chips and promotes longer periods between tool changes.

Geometry that delivers consistent dimensional accuracy

The Rhombic 35° form and the 0.4 mm corner radius create a balance between strength and finish quality. A small corner radius like this helps to achieve precise diameters and fine surface quality while the 7° relief angle prevents rubbing and lowers cutting forces. The insert size and thickness are matched to conventional turning toolholders, ensuring repeatable seating and true running. These geometric choices translate directly into fewer reworks and predictable cycle times.

Broad application scope with Tiger·tec Silver performance

This insert is part of the Tiger·tec Silver family and is intended for machining across ISO groups M and S, meaning stainless steel as well as heat-resistant superalloys and titanium alloys are within its capability range. The coating and substrate combination emphasise edge stability under elevated temperatures and difficult chip formation tendencies, enabling safer machining of tough-to-cut materials. For workshop operations handling mixed materials, this insert offers a pragmatic option that reduces tool inventory while maintaining process reliability.

Practical fit for production and job-shop environments

The insert’s design focuses on productive machining rather than niche applications: the FM4 chipbreaker moderates chips in medium to heavy cuts while the coated grade helps sustain the edge during intermittent cuts and higher thermal loads. For users migrating from conventional grades, the insert provides predictable behaviour during ramping and profiling, reducing set-up variability. When integrated into stable toolholder systems, the result is smoother production runs and improved first-pass yields.

FAQ

Is this insert suitable for stainless steel?
Yes. The VCMT160404-FM4 WSM30S from Walter Tools is specifically specified for stainless steel (ISO group M) and is optimised for secure chip formation and edge stability in such materials.

Can the insert be used for heat-resistant superalloys or titanium?
The WSM30S grade is designed for applications in both ISO S materials and stainless steel, so it is suitable for many heat-resistant superalloys and titanium alloys depending on the machining strategy and machine rigidity.

What benefits does the FM4 chipbreaker provide?
The FM4 chipbreaker supports consistent chip control across a range of cutting depths, helping to avoid long, stringy chips and improving process reliability when turning difficult materials with the Walter Tools insert.

How does the Rhombic 35° geometry affect turning performance?
The Rhombic 35° shape offers a favourable approach angle for general turning, balancing cutting-edge strength and surface finish. It is particularly effective where a compromise between heavy cuts and fine finishing is required.

Is the coating suitable for interrupted cuts and higher temperatures?
Yes. The Tiger·tec Silver coating on the VCMT160404-FM4 WSM30S is selected to improve thermal resistance and maintain a stable cutting edge under elevated temperatures and intermittent engagement.
