VCMT160404-MM4 WSM10S – Indexable turning insert, Tiger·tec Silver coating, 0.4 mm radius (Walter Tools)

The VCMT160404-MM4 WSM10S is a coated indexable turning insert designed for stable machining of stainless steels and heat‑resistant superalloys in demanding production environments.

• Tiger·tec Silver coating for edge stability
• Optimised MM4 chipformer for controlled chips
• Rhombic 35° geometry for versatile turning
• 0.4 mm corner radius for robust cutting edge

Longer tool life and targeted material performance

The insert combines the Tiger·tec Silver coating with the WSM10S grade to provide improved resistance to wear and thermal loading when cutting difficult materials. This formulation supports stable chip formation and reduces notch wear, which translates into longer tool life and fewer indexings in serial production. The result is a measurable uplift in process reliability when machining stainless steels and high‑temperature alloys, offering a clear efficiency advantage on parts with frequent tool engagement.

Controlled chips and secure process stability

Equipped with an MM4 chipformer and a defined 0.4 mm corner radius, the geometry ensures predictable chip breaking and evacuation under moderate to heavy cutting conditions. The 7° clearance angle and rhombic 35° form create a favourable cutting approach that reduces cutting forces while maintaining edge security, which supports consistent tolerances and surface finish across batches. These features are particularly beneficial in setups where stable chip control directly reduces cycle time and downstream cleaning effort.

Geometry and tolerances for precise turning

The medium tolerance class (M), the 16 mm insert size and the 4 mm thickness support repeatable seating and dependable indexability in standard toolholders. The rhombic 35° shape allows both light finishing and profile turning tasks with a single indexable geometry, making it a versatile choice for mixed production. Walter Tools’ grade selection aims to balance productivity with surface quality, ensuring the insert performs reliably across a wide range of turning applications without frequent requalification of the machining process.

FAQ

What materials is this insert suitable for?
The VCMT160404-MM4 WSM10S from Walter Tools is designed for stainless steels and heat‑resistant superalloys (ISO groups M and S), with the coating and grade tuned for secure chip formation and thermal stability.

How does the MM4 chipformer benefit the machining process?
The MM4 chipformer on this insert promotes predictable chip breaking and evacuation; in practice this reduces chip interference and helps maintain consistent surface finish when using the VCMT160404-MM4 WSM10S in serial turning operations.

Can this insert be used for finishing as well as roughing?
Yes, the rhombic 35° geometry combined with a 0.4 mm corner radius enables versatile use from finishing to medium roughing, depending on the chosen cutting parameters and toolholder rigidity.

What tolerance class and dimensions should be expected for tool changeovers?
The insert has a medium tolerance class (M), a nominal size of 16 mm and a thickness of 4 mm, which supports reliable seating and repeatable indexability across compatible holders.

Is the Tiger·tec Silver series aimed at general or specialised applications?
Tiger·tec Silver is engineered for productive machining of demanding materials; the WSM10S grade particularly targets applications where edge stability and thermal resistance are required, offering a balance of productivity and surface quality.
