VCGT160402-MM4 WSM01 indexable turning insert – Rhombic 35°, 7° clearance | Walter Tools

VCGT160402-MM4 WSM01 is an indexable turning insert designed for demanding turning operations on stainless steels and heat‑resistant superalloys

• Tiger-tec Silver coating for heat resistance
• WSM01 grade for stainless and superalloys
• Rhombic 35° geometry for versatile turning
• Stable chip control with MM4 breaker

Greater process reliability through advanced coating and grade

The Tiger-tec Silver coating combined with the WSM01 carbide grade delivers a balance of thermal resistance and edge stability for continuous turning operations. This configuration reduces edge wear during high thermal loads and supports a predictable tool life, which translates into fewer interruptions on the shopfloor and improved machine utilisation. The coated carbide is specifically engineered to maintain cutting integrity in applications with elevated temperatures and adhesive tendencies, such as rostfreier Stahl and nickel‑based alloys, allowing for higher cutting parameters without compromising surface quality.

Consistent chip control and geometry benefits for varied turning tasks

The MM4 chipbreaker is matched to the insert’s rhombic 35° profile and 0.2 mm corner radius to promote controlled chip formation in medium to heavy cuts. The combination of an acute insert angle and the 7° clearance angle reduces cutting forces during entry and exit while improving access in shoulder and profile turning. As a consequence, machining stability is enhanced and secondary operations are often reduced. For operators less familiar with chipbreaker functions: MM4 directs and segments chips to avoid long, tangled swarf, improving safety and reducing cycle interruptions.

Broad material range and application-oriented performance

This insert is suitable for materials classified under ISO as M and S—notably stainless steels and heat‑resistant superalloys (and depending on geometry, certain titanium applications). The WSM01 grade is optimised for secure chip formation and stable cutting edges when confronted with workpieces that tend to gall or generate high temperatures. For production engineers this means fewer unexpected tool changes and more consistent part tolerances, especially in serial production where repeatability and surface finish are critical.

Productivity gains and integration into industrial turning shops

Adopting this insert supports a rational approach to productivity: extended edge life and repeatable performance lower total tool consumption and reduce throughput variability. The insert’s proven chip control and thermal resistance reduce the risk of built‑up edge and rework, providing a tangible cost‑benefit in medium‑ to high‑volume turning. Integration into existing tooling systems is straightforward for holders accepting VCGT‑format inserts, enabling fast replacement and minimal setup time while preserving process safety.

FAQ

What materials are suitable for this insert?
The VCGT160402‑MM4 WSM01 insert is intended for ISO material groups M and S, primarily rostfreier Stahl (stainless steels) and heat‑resistant superalloys; performance in titanium depends on the chosen cutting parameters and holder geometry.

How does the WSM01 grade support machining of difficult materials?
WSM01 is a coated carbide grade optimised for thermal resistance and stable edge behaviour, which helps prevent adhesion and supports consistent chip formation when machining tougher alloys.

What is the advantage of the rhombic 35° shape with a 0.2 mm corner?
The rhombic 35° profile offers good access for profile turning and facing, while the 0.2 mm corner radius balances edge strength and surface finish for general turning operations.

How does the MM4 chipbreaker improve process safety?
The MM4 breaker segments and guides chips to avoid long, stringy swarf, reducing the risk of chip entanglement and enabling more reliable unattended operation.

Is this insert compatible with standard VCGT holders?
The insert follows the VCGT160402 format; holders designed for VCGT inserts of size 16 should accept it—verify holder specifications for clearance and clamping method.
