VBMT160404-MM4 WSM01 – Indexable turning insert, Rhombus 35°, 0.4 mm corner radius (Walter Tools)

The VBMT160404-MM4 WSM01 is an indexable turning insert designed for demanding turning applications on stainless steel and heat‑resistant superalloys, offering a compact rhombic 35° geometry for stable engagement

• Tiger‑tec Silver coated carbide for long life
• Stable chip formation with MM4 chipbreaker
• 5° clearance and rhombic 35° geometry
• 0.4 mm corner radius for consistent edge strength

Process security for stainless steel and superalloys

The coated carbide grade from the Tiger‑tec Silver series is formulated for materials classified under ISO group M and S. With this insert, operators achieve stable chip formation even when cutting tough, heat‑retaining alloys; the MM4 chipbreaker supports predictable chip shapes that reduce vibration and lower the risk of built‑up edge. The result is fewer interruptions, higher surface consistency and improved cycle reliability for batch and single‑part production.

Geometry engineered for repeatable edge performance

A rhombic 35° insert form with a 5° clearance angle concentrates cutting forces in a compact contact zone, which helps maintain a robust cutting edge during interrupted cuts or variable feed conditions. The 0.4 mm corner radius balances edge strength and form accuracy, reducing the rate of edge chipping while preserving a controlled cutting profile. This geometry translates into longer effective tool life and consistent part tolerances in serial turning operations.

Coating and chip control to increase productivity

The combination of a modern coating system and a coated hardmetal substrate improves wear resistance and heat management at the cutting edge. The Tiger‑tec Silver coating reduces flank wear and supports higher cutting speeds where applicable. By pairing this with the MM4 chipbreaker, the insert enhances material evacuation and tool stability, which together result in more productive cutting windows and less machine downtime for chip‑related issues.

Practical compatibility and handling advantages

The insert is supplied in the VBMT160404 format with thickness code 04 and an inscribed size denoted as 16, tolerance class M, matching common clamping systems for indexable turning tools. Its classification for machining stainless steel and heat‑resistant superalloys (ISO groups M and S) makes it a versatile choice for mixed‑material production environments. The compact form factor and standard interface simplify tool setup and stock management in workshop and production contexts.

FAQ

What materials is this insert suitable for?
The VBMT160404-MM4 WSM01 insert is specified for stainless steel (ISO group M) and heat‑resistant superalloys/titanium (ISO group S) thanks to its coated carbide grade and MM4 chipbreaker.

How does the MM4 chipbreaker improve machining?
The MM4 chipbreaker on the Walter Tools VBMT160404-MM4 WSM01 promotes predictable chip shapes and controlled evacuation, reducing vibration and improving surface finish during turning.

What does the 0.4 mm corner radius mean in practice?
A 0.4 mm corner radius increases edge robustness and reduces chipping risk while maintaining dimensional control, making the insert suitable for both finishing and light roughing cuts when geometry and parameters are matched.

Is the insert compatible with common toolholders?
The VBMT160404 format and tolerance class M follow standard indexable insert interfaces; compatibility depends on the chosen toolholder pocket designed for VBMT inserts.
