VCGT110304-MM4 WSM20S — Turning indexable insert, Tiger·tec Silver, Rhombus 35° (Walter Tools)

The VCGT110304-MM4 WSM20S is a rhombic 35° turning insert designed for productive machining of stainless steel and heat‑resistant superalloys in demanding turning operations.

• Tiger·tec Silver coated grade WSM20S
• Optimised MM4 chipbreaker for stable chips
• Rhombus 35° with 0.4 mm corner radius
• Suitable for stainless steel and high‑temp alloys

Increase uptime through a wear‑resistant grade

The Tiger·tec Silver WSM20S grade provides a balanced combination of wear resistance and thermal stability, which is particularly valuable when machining tough materials such as stainless steel and heat‑resistant superalloys. The coated carbide construction supports a stable cutting edge under elevated temperatures, reducing flank wear and the frequency of insert changes. The result is more predictable tool life and fewer unscheduled stops, delivering measurable gains in process efficiency and reduction in rework.

Consistent surface quality thanks to optimised chip control

The MM4 chipbreaker together with the Rhombus 35° geometry ensures controlled chip formation and secure evacuation even in challenging materials. A 0.4 mm corner radius and 7° clearance angle combine to lower cutting forces and support a consistent surface finish, which translates into fewer downstream finishing operations. For shop floors aiming to tighten tolerances and reduce secondary machining, the geometry helps to produce repeatable, high‑quality parts cycle after cycle.

Designed for integration into industrial turning systems

Marked as S / M for its material scope, the insert is suited to both superalloys/titanium (S) and stainless steels (M), enabling a single grade to cover several hard‑to‑cut material families. The standard VCGT form and the VCGT110304‑MM4 designation permit straightforward mounting in common toolholders, easing inventory management and minimising tool change complexity. The stable edge behaviour under cutting and the coating’s heat management capability support higher productivity and consistent component quality within established machining strategies.

Practical support and process advice for secure implementation

For shops assessing the grade for specific process windows, technical advice is available to match cutting data and coolant strategy to the workpiece material and machine capability. Metav Werkzeuge and the manufacturer’s application literature provide guidance on selecting feeds, speeds and insert orientation to make the most of the Tiger·tec Silver technology while safeguarding tool life. For complex components or mixed‑material batches, coordinated process support helps to avoid trial‑and‑error and to accelerate reliable production ramp‑up.

FAQ

What materials is this insert intended for?
The VCGT110304‑MM4 WSM20S insert from Walter Tools is formulated for stainless steels and heat‑resistant superalloys (S / M designation), offering secure chip formation and edge stability in these groups.

Which insert geometry yields the best surface finish?
The Rhombus 35° form with a 0.4 mm nose radius on the WSM20S grade supports lower cutting forces and consistent surface quality, making it a reliable choice for finishing and semi‑finishing passes.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker is optimised for controlled chip segmentation and evacuation; when combined with the Tiger·tec Silver coating it helps to reduce built‑up edge and maintain a stable cutting edge under thermal load.

Can the insert be used in standard toolholders?
Yes; the VCGT form is a common indexable insert style and the VCGT110304‑MM4 designation allows simple integration into matching holders, easing tool changeover and stock management.

Is this a coated or uncoated grade?
The WSM20S is a coated carbide grade from the Tiger·tec Silver series, designed to improve wear resistance and thermal performance in demanding turning tasks.
