VCGT160404-MM4 WSM01 – Turning indexable insert, MM4 chipbreaker (Walter Tools)

VCGT160404-MM4 WSM01 is a coated turning indexable insert designed for robust machining of rostfreier Stahl and heat-resistant superalloys, offering a balance of edge stability and chip control

Tiger‑tec Silver series grade WSM01
MM4 chipbreaker for controlled chip formation
Rhombic 35° geometry with 7° clearance
0.4 mm corner radius for reliable edge support

Optimised grade for demanding materials and consistent cutting

The WSM01 grade from the Tiger‑tec Silver series is a coated carbide formulation developed for the reliable machining of challenging alloys. It is specified for applications in the ISO groups M (rostfreier Stahl) and S (heat‑resistant superalloys and titanium), where material toughness and heat generation demand a cutting grade that maintains a stable cutting edge. The chemistry and coating are selected to promote secure chip formation and to limit edge build‑up; this results in predictable tool life and reduced unplanned downtime. For production environments that prioritise consistency when turning difficult materials, the tailored grade supports repeatable component quality and helps to meet cycle‑time targets.

Geometry and chip control that improve surface finish and process reliability

The rhombic 35° insert outline combined with a 7° clearance angle reduces flank rubbing while maintaining cutting strength in radial cuts. The MM4 chipbreaker is engineered to produce manageable chip shapes in tougher workpiece materials, decreasing the likelihood of built‑up edge and improving surface finish. A 0.4 mm corner radius increases edge robustness, distributing cutting forces to extend in‑process stability during interrupted cuts and heavy feed conditions. Together, these geometric attributes translate into lower scrap rates and a higher first‑pass yield for components that require precise diameters and controlled surface quality.

Productivity gains through tailored application and repeatable performance

Adopting this insert supports a rational productivity strategy: the combination of grade and chipformer offers longer intervals between index changes and consistent dimensional control. The insert designation VCGT160404‑MM4 WSM01 indicates a standard ISO geometry that integrates easily into existing tool holders while delivering process security on rostfreier Stahl and the specified superalloys. For job shops and production lines where throughput and reproducibility are key performance indicators, the design reduces cycle variability and simplifies tool inventory management by aligning a single, robust grade to multiple hard‑to‑machine materials.

FAQ

Is this insert suitable for rostfreier Stahl machining?
Yes. The WSM01 grade is specified for ISO group M, making the insert suitable for machining rostfreier Stahl where toughness and thermal load require a coating and grade that support secure chip formation.

What advantages does the MM4 chipbreaker offer?
The MM4 chipbreaker provides controlled chip segmentation in tougher materials, improving chip evacuation and reducing the risk of built‑up edge, which helps maintain consistent surface finish and tool life for the described insert.

How does the rhombic 35° geometry affect cutting?
The rhombic 35° outline offers a versatile cutting angle that balances insert strength and access for turning; combined with the 7° clearance, it reduces flank contact and supports reliable dimensional control in radial and axial cuts.

When is a 0.4 mm corner radius recommended?
A 0.4 mm corner radius is appropriate where increased edge support is needed to withstand higher cutting forces or light roughing to finishing transitions; this radius helps the insert resist chipping while maintaining acceptable surface integrity.
