VCGT110302-MM4 WSM20S indexable turning insert — Walter Tools, Rhombic 35°, Tiger·tec Silver

VCGT110302-MM4 WSM20S is an indexable turning insert designed for demanding turning applications in stainless steel and superalloys

• Tiger·tec Silver coating for heat resistance and longer life
• MM4 chipbreaker for stable chip formation
• Rhombic 35° geometry for versatile external turning
• 0.2 mm corner radius for controlled finish and strength

High process reliability and extended tool life through coating and grade

The combination of the Tiger·tec Silver coating and the WSM20S grade provides enhanced thermal resistance and wear behaviour for demanding turning tasks. The coated cemented‑carbide formulation is optimised for poor heat conduction materials: it reduces adhesion and supports stable cutting edges during intermittent and continuous cuts. As a result, tool life is extended and unplanned tool changes are reduced, improving throughput in batch production and high‑mix environments.

Secure chip control and consistent surface quality

Equipped with the MM4 chipbreaker and a 0.2 mm corner radius, this insert delivers predictable chip formation and consistent surface finishes. The Rhombic 35° shape favours a balanced approach between strength and accessibility, allowing effective engagement on external diameters and shoulder turning. Where surface integrity matters, the geometry helps maintain dimensional stability while avoiding excessive cutting forces that can lead to chatter.

Suitable for stainless steel and high‑temperature alloys (ISO M & S)

The insert is tailored to machine materials classified in ISO groups M and S, notably stainless steel and heat‑resistant superalloys or titanium. These materials tend to work‑harden and generate higher temperatures at the cutting zone; the Tiger·tec Silver technology and robust grade selection support secure chip evacuation and edge retention under these conditions. For customers transitioning from conventional grades, the result is fewer built‑up edges and reduced rework.

Practical benefits for production workflows

Compact sizing and a proven insert form simplify tool indexing and inventory management. The VCGT110302‑MM4 WSM20S insert can be integrated into existing toolholders that accept VCGT‑style inserts, offering an immediate performance upgrade without extensive requalification. Production managers benefit from consistent reproducibility, lower reject rates and a dependable option for mixed‑material machining lists.

FAQ

Which materials are recommended for this insert?
The VCGT110302‑MM4 WSM20S insert from Walter Tools is intended for stainless steel and heat‑resistant superalloys (ISO groups M and S), where thermal stability and edge security are required.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker delivers consistent chip control and reduces the risk of built‑up edge when turning tough materials; this improves surface finish and decreases downtime for chip‑related issues on Walter Tools inserts.

What surface quality can be expected with the 0.2 mm corner radius?
A 0.2 mm corner radius balances edge strength and finish capability, enabling good surface integrity in finishing passes while maintaining sufficient robustness for slight interruptions.

Is this insert suitable for both continuous and interrupted cuts?
Yes — the coated grade and the Rhombic 35° form are designed to cope with a range of cutting conditions, including moderate intermittent cuts typical in external turning operations.
