CCMT120408‑MM4 WSM10S — Indexable Insert for Drilling/Boring & Turning, Tiger·tec Silver (Walter Tools)

The CCMT120408‑MM4 WSM10S is a rhombic 80° indexable insert in the Tiger·tec Silver family, designed for secure chip control and edge stability when machining stainless steel and high‑temperature alloys.

• Tiger·tec Silver coating for edge stability
• Optimised MM4 chipbreaker for secure chips
• Rhombic 80° form with 0.8 mm corner radius
• Suited to stainless steel and superalloys

Consistent cutting performance for difficult materials

The combination of the Tiger·tec Silver coating and the WSM10S grade delivers a balance of wear resistance and thermal stability that supports sustained cutting performance in demanding applications. The coated cemented carbide substrate moderates adhesion and reduces the tendency for built‑up edge on stainless steel, while the MM4 chipbreaker promotes predictable chip formation. This results in fewer interruptions for chip clearing and improved repeatability across production batches, which supports higher process reliability and reduced scrap rates.

Geometry engineered for repeatable surface quality

A rhombic 80° shape with a 0.8 mm corner radius and a 7° relief angle provides a robust cutting edge geometry that is tolerant to varying engagement conditions. The insert’s form permits versatile toolholder arrangements for drilling/boring and turning operations, while the corner radius helps to distribute cutting forces and improve surface finish on parts made from tough, work‑hardening alloys. The plate dimensions (inscribed circle 12 and thickness 4) give a stable seat in the toolholder and support consistent cutting depth control.

Practical machining advantages and recommendations

Designed primarily for machining stainless steel (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), the insert’s coating and chipbreaking geometry reduce edge wear and support longer tool life in interruption‑prone cuts. For best results, combine the insert with appropriate coolant strategies and validated holder geometry; the controlled chip form from the MM4 breaker simplifies evacuation in deep bores and narrow grooves. Application tuning—cutting speed, feed and depth of cut—should be selected according to machine rigidity and material batch; Metav Werkzeuge can provide cutting data and matching toolholder suggestions.

Productivity and cost‑efficiency in production

By improving tool life and reducing unplanned tool changes, the insert contributes to lower unit costs and less machine downtime. The Tiger·tec Silver technology emphasises process security and stable cutting edge behaviour, which supports consistent part quality and predictable maintenance intervals. For operations requiring high availability and repeatable surface outcomes, this insert offers a pragmatic balance between performance and productivity.

FAQ

Which materials is this insert intended for?
The CCMT120408‑MM4 WSM10S insert is intended for stainless steel (ISO group M) and heat‑resistant superalloys/titanium (ISO group S) thanks to the Tiger·tec Silver coating and the MM4 chipbreaker.

What advantages does the MM4 chipbreaker offer?
The MM4 chipbreaker provides controlled chip form and secure evacuation, reducing interruptions and helping to maintain consistent surface finish when machining difficult materials.

Can the insert be used for both drilling/boring and turning?
Yes, the rhombic 80° geometry and the specified thickness and size permit use in suitably configured toolholders for drilling/boring and turning operations.

How does the corner radius affect component finish?
A 0.8 mm corner radius balances edge strength and finish quality: it helps distribute cutting forces for longer edge life while supporting a good surface quality on work‑hardened alloys.

Is the Tiger·tec Silver technology beneficial for high‑temperature alloys?
The Tiger·tec Silver technology enhances thermal stability and wear resistance, which is particularly beneficial when machining high‑temperature alloys and materials that generate significant cutting heat.
