WCMT06T308-FM4 WSM20S — Trigon 80° Turning and Boring Insert, Tiger‑tec Silver (Walter Tools)

A WCMT06T308-FM4 WSM20S trigon insert designed for turning and boring applications, optimised for stainless steel and high‑temperature alloys.

• Tiger‑tec Silver coating for thermal stability
• WSM20S grade for stainless steel and superalloys
• Trigon 80° form with 0.8 mm corner radius
• FM4 chipbreaker for consistent chip control

Greater process stability through optimized coating and grade

The Tiger‑tec Silver coating combined with the WSM20S coated‑carbide grade improves thermal resistance and edge life when machining demanding materials. This engineered surface treatment reduces adhesion and softening at the cutting edge, which leads to fewer edge‑related interruptions and a more consistent machining cycle. For workshops handling stainless steel and heat‑resistant alloys, this means longer tool wearing intervals and reduced operator interventions, supporting a steady production flow and predictable tool‑change planning.

Geometry that delivers reliable cutting performance

The insert’s Trigon 80° geometry and 0.8 mm radius provide a compromise between strength and accessibility: the larger approach angle increases insert strength for interrupted cuts, while the corner radius supports a robust cutting edge for stable finish passes. A 7° clearance angle and T3 thickness ensure correct seat engagement and stiffness in common toolholders. The FM4 chipbreaker was developed to produce controlled chip forms across a range of depths of cut, which helps to maintain coolant effectiveness and minimises the risk of chip entanglement, reducing rework and down‑time.

Application advantages and recommended use

This insert is intended for machining stainless steel (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), where heat generation and edge wear are critical. The insert’s combination of coating and geometry supports both roughing operations—where chip control and edge security are essential—and finishing passes that require good surface quality. For best results, pair the insert with a compatible indexable insert holder designed for trigon inserts and apply cutting parameters adapted to the workpiece alloy and rigidity of the machine; the result is improved productivity and consistent component quality with fewer unexpected interruptions. The WCMT06T308-FM4 WSM20S insert thus contributes to reproducible process outcomes in serial production.

FAQ

What materials is this insert suitable for?
The WCMT06T308-FM4 WSM20S insert is formulated for stainless steel (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), where thermal stability and edge strength are required.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker produces a controlled chip form that improves chip evacuation and coolant access, supporting continuous operation and reducing the risk of chip‑related interruptions when using the insert.

What advantage does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver enhances thermal resistance and reduces built‑up edge, which extends tool life and maintains cutting performance on abrasive or adhesive materials when using this Walter Tools insert.

Can the Trigon 80° form be used for both roughing and finishing?
Yes, the Trigon 80° geometry combined with a 0.8 mm corner radius offers the strength needed for roughing and the edge stability required for medium finishing operations with this turning and boring insert.

Is this insert compatible with standard trigon toolholders?
The insert’s Trigon 80° form and ISO designation WCMT06T308-FM4 WSM20S align with standard indexable insert holders designed for trigon inserts; correct seating and clamping according to the holder manufacturer’s instructions are recommended.
