CCMT09T308-MM4 WSM30S turning insert, Tiger·tec Silver — designed for rostfreier Stahl and heat-resistant alloys (Walter Tools)

The CCMT09T308-MM4 WSM30S is a rhombic 80° turning insert developed for heavy-duty and difficult-to-machine materials, offering a balance of edge stability and chip control for modern production environments

• Tiger·tec Silver coating
• MM4 chipbreaker for controlled chips
• Suitable for rostfreier Stahl and superalloys
• Rhombic 80° form with 0.8 mm radius

Consistent productivity when machining rostfreier Stahl and superalloys

The combination of the Tiger·tec Silver coating and the WSM30S grade provides a clear productivity advantage when processing rostfreier Stahl and heat-resistant alloys. The advanced coating reduces thermal load and wear on the cutting edge, which translates into longer tool life and fewer indexings per workpiece. For production-oriented shops this means higher uptime and reduced tooling costs over time. The coated substrate supports a robust cutting edge that resists built-up edge and maintains dimensional consistency during extended runs.

Reliable chip control and edge integrity for safer turning

Built-in MM4 chip control ensures predictable chip breaking under a wide range of cutting conditions, improving swarf handling and machine safety. The 0.8 mm corner radius smooths load transitions at the cutting edge and reduces the tendency for notch formation during interrupted cuts. As a result, the insert promotes stable chip formation and reduces the need for secondary finishing, which benefits both cycle time and surface quality in serial production.

Geometry that balances strength and access for varied applications

The Rhombic 80° profile combines penetrating geometry with sufficient edge support to withstand moderate depths of cut. With a clearance angle of 7° and a plate thickness of T3, the insert is designed to offer a compromise between rigidity and cutting accessibility in confined tool holders. This geometry supports reliable performance in facing and turning operations where tool overhang or limited approach angles would otherwise restrict insert choice.

Material grouping and recommended use cases explained

The insert is optimised for ISO material groups M and S, meaning it is particularly suited to rostfreier Stahl (M) and heat-resistant superalloys or titanium (S). Materials in these groups generate heat at the cutting zone and can produce long, stringy chips; the WSM30S grade and the MM4 chipbreaker help to mitigate these issues by improving thermal resistance and chip breaking. For customers less familiar with ISO grouping: M = stainless steels; S = hot-work steels, superalloys and titanium. Selecting appropriate cutting data and coolant strategies further enhances tool life and process reliability.

FAQ

What materials is this insert suitable for?
The CCMT09T308-MM4 WSM30S insert is specified for ISO groups M and S, making it suitable for rostfreier Stahl and heat-resistant superalloys depending on geometry and cutting data.

How does the Tiger·tec Silver coating benefit performance?
The Tiger·tec Silver coating on the WSM30S grade improves thermal resistance and wear behaviour, which enhances edge life and process stability in demanding turning applications.

Which chipbreaker should be expected and what is its effect?
This insert uses the MM4 chipbreaker, designed to produce controlled, short chips in a wide range of feed and depth combinations, aiding safe chip disposal and consistent surface finish.

Can the insert handle interrupted cuts and heavier engagement?
The Rhombic 80° geometry together with the 0.8 mm corner radius provides robust edge support that tolerates moderate interruptions and heavier engagement better than sharper radii.
