WCMT06T304-FM4 WSM30S — Boring / reaming indexable insert / turning indexable insert by Walter Tools, Trigon 80° with 7° clearance

The WCMT06T304-FM4 WSM30S is an indexable insert designed for heavy-duty machining of stainless steel and heat-resistant alloys, combining Tiger·tec Silver coating with a Trigon 80° form

• Tiger·tec Silver coated grade WSM30S
• Suited for stainless steel and superalloys
• Trigon 80° geometry, 0.4 mm corner radius
• FM4 chipbreaker for secure chip control

High-performance grade for demanding materials

The combination of the WSM30S grade and the Tiger·tec Silver coating is engineered for stability when machining stainless steel and heat-resistant superalloys. The coated carbide substrate provides improved edge life and thermal resistance, which supports a predictable tool life even under challenging workpiece conditions. This indexable insert's specification emphasises controlled chip formation and reduced risk of built-up edge, translating into fewer interruptions and a steadier production output. The engineering focus is on achieving consistent surface quality and repeatable dimensional results when processing tough-to-machine alloys.

Geometry and chip control that protect productivity

The Trigon 80° plate form with a 0.4 mm corner radius and 7° clearance angle offers a robust cutting edge while maintaining the necessary clearance to avoid rubbing. The FM4 chipbreaker is tailored to break and evacuate chips effectively in interrupted or continuous cuts typical for boring and turning operations. These geometry choices reduce cutting forces and support stable cutting conditions, which in turn lowers the likelihood of tool chatter and improves overall process reliability. The insert’s thickness T3 and the specified plate size ensure secure clamping in most standard indexable holders for turning and boring.

Application guidance and process advantages

This insert is intended for operations where material workability is limited by toughness or poor thermal conductivity — specifically stainless steel (ISO group M) and superalloys/titanium (ISO group S). Where moderate to heavy cutting is required, the coated grade offers a balance of wear resistance and edge toughness. When implementing this insert, pair it with a rigid toolholder and appropriate cutting parameters for the material class; modestly increased feed and conservative speeds for superalloys, and optimised coolant use for stainless steel, will enhance performance. The result is improved process security, fewer tool changes and more predictable production cycles.

FAQ

What materials is this insert suitable for?
The WCMT06T304-FM4 WSM30S is suited for stainless steel (ISO group M) and for heat-resistant superalloys/titanium (ISO group S), reflecting the grade’s focus on thermal and edge stability.

How does the Tiger·tec Silver coating benefit machining?
Tiger·tec Silver on this insert enhances thermal resistance and wear behaviour, providing longer edge life and more consistent performance in the demanding conditions encountered when machining stainless steel and superalloys.

Is the Trigon 80° form suitable for boring operations?
Yes — the Trigon 80° geometry delivers a sturdy cutting edge angle appropriate for both turning and boring tasks, offering a good balance between strength and accessibility in internal operations.

What is the purpose of the FM4 chipbreaker?
The FM4 chipbreaker is configured to produce controllable chip shapes and to evacuate chips reliably, which reduces the risk of chip congestion and supports uninterrupted machining cycles.

Can this insert be used in standard Walter toolholders?
The insert’s WCMT designation and plate size are compatible with standard indexable turning and boring holders designed for Trigon 80° inserts; confirm seat and clamping specifications with Metav Werkzeuge for exact compatibility.
