WCMT040202-FM4 WSM30S — Trigon 80° indexable insert for drilling and turning, Walter Tools

A WCMT040202-FM4 WSM30S indexable insert engineered for demanding drilling, bore‑enlarging and turning operations on stainless steels and high‑temperature alloys.

• WCMT040202-FM4 WSM30S by Walter Tools
• Tiger‑tec Silver coating for heat resistance
• Trigon 80° form, 7° clearance, 0.2 mm radius
• For stainless steels and heat‑resistant alloys

Optimised grade and coating for tough materials

The combination of Tiger‑tec Silver and the WSM30S grade provides a coated carbide solution engineered specifically for difficult‑to‑cut materials. The coating enhances thermal stability and reduces built‑up edge, while the substrate maintains the toughness required under interrupted cuts. For workshops processing stainless steels (ISO group M) or superalloys and titanium (ISO group S), this insert improves process stability and reduces downtime by supporting repeatable cutting performance and controlled wear patterns.

Geometry that improves stability and surface finish

Designed with a Trigon 80° profile, a 0.2 mm corner radius and a relief angle of 7°, the insert geometry balances edge strength and accessibility in axial and radial engagement. The FM4 chipbreaker supports predictable chip formation and evacuation under the high heat loads typical of these materials. Together, these features reduce vibration and enhance surface integrity, so the tooling contributes directly to consistent component tolerances and less rework in production.

Practical benefits for production and tooling strategy

Using this indexable solution shortens set‑up variation and supports higher process reproducibility. The coated carbide grade reduces the frequency of insert changes, which lowers handling time and tooling inventory pressure. In mixed‑material production environments where stainless steels and heat‑resistant alloys are machined, the insert’s balance of wear resistance and edge stability enables longer cutting windows and fewer emergency tool changes, improving overall throughput and reducing scrap rates.

FAQ

What materials is this insert suitable for?
The WCMT040202-FM4 WSM30S insert is suitable for stainless steels (ISO group M) and heat‑resistant superalloys and titanium (ISO group S), thanks to the WSM30S grade and Tiger‑tec Silver coating.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker on this turning/drilling insert promotes predictable chip formation and evacuation, improving surface finish and reducing the risk of built‑up edge when machining challenging alloys.

Can the Trigon 80° form be used for both turning and drilling operations?
Yes, the Trigon 80° profile offers a versatile geometry that supports both turning and bore‑enlarging operations where access and edge strength are required.

What does the 0.2 mm corner radius mean for component quality?
A 0.2 mm corner radius increases edge robustness compared with a sharper tip, reducing notch wear and improving dimensional stability on finished components.

Is this insert a coated carbide type?
Yes, the WCMT040202-FM4 WSM30S is a coated carbide insert from the Tiger‑tec Silver series, designed to balance hardness and toughness for long tool life.
