VBMT160404‑MM4 WSM20S indexable turning insert, Tiger‑tec Silver, for stainless and heat‑resistant alloys — Walter Tools

A VBMT160404‑MM4 WSM20S indexable insert engineered for reliable turning of tough-to-machine stainless steel and high-temperature alloys, offering a balanced geometry for consistent surface quality and chip control

• Tiger‑tec Silver coating for heat resistance
• Stable MM4 chipbreaker for consistent chips
• Rhombus 35° form for versatile turning
• 0.4 mm corner radius and 5° clearance

Consistent machining through advanced coating and grade

The Tiger‑tec Silver coating together with the WSM20S grade provides elevated heat resistance and edge stability when machining stainless steel and superalloys. This leads to longer tool life and fewer unscheduled tool changes, which directly improves process uptime. The coated cemented carbide substrate is formulated to maintain a stable cutting edge under thermal load, so operators benefit from predictable wear behaviour and reduced rework.

Accurate surface finish and controlled cutting behaviour

The Rhombus 35° geometry combined with the MM4 chipbreaker and a 0.4 mm corner radius creates a cutting profile that supports smooth chip formation and reliable evacuation. The 5° clearance angle reduces rubbing and minimises built-up edge, improving surface quality on demanding materials. As a result, the insert enables stable finishing cuts with lower cutting forces and consistent part tolerances, which supports tight production specifications.

Application-focused performance for stainless and heat‑resistant alloys

Designed for machining group M (stainless steels) and group S (heat‑resistant alloys and titanium), this insert delivers high process security in serial production and repair work alike. The combination of coating, grade and chipbreaker promotes safe chip control in difficult-to-machine alloys, reducing cycle variability. For production environments seeking repeatable quality and reduced downtime, the insert represents a technical investment in productivity and component integrity.
