CNMG120408-MM5 WSM10S indexable turning insert — Tiger·tec Silver, Walter Tools

The CNMG120408-MM5 WSM10S is a negative‑side, rhombic 80° indexable insert designed for robust turning in stainless steels and heat‑resistant superalloys, offering controlled chip formation and high thermal resistance.

• Tiger·tec Silver coating for heat resistance
• MM5 chipbreaker for consistent chip control
• Rhombic 80° form, 0.8 mm corner radius
• 0° negative free angle for robust turning

Process security when machining stainless steels and superalloys

The coated‑carbide grade WSM10S delivers a combination of thermal stability and edge integrity that supports predictable performance when machining challenging materials. Designed within the Tiger·tec Silver series, this grade is optimised for applications in stainless steels (ISO group M) and heat‑resistant superalloys or titanium (ISO group S). The material‑matched coating reduces built‑up edge and improves resistance to elevated cutting temperatures, which in turn lowers the frequency of tool changes and supports uninterrupted production cycles.

Consistent chip control and surface quality

Chip control is achieved through the MM5 chipbreaker geometry together with the Rhombus 80° plate form and a 0.8 mm corner radius. This combination produces short, controllable chips on interrupted cuts and continuous turning operations alike, reducing the risk of surface damage and stabilising cutting forces. The 0° negative free angle contributes to mechanical robustness, making the insert suitable for heavier cuts and applications where a secure tool edge is required.

Extended tool life and predictable economy

The Tiger·tec Silver technology focuses on wear resistance and edge stability to extend service life under demanding conditions. With optimised coating and substrate pairing, the insert offers a balance between toughness and hardness, which supports repeatable performance and predictable replacement intervals. The result is improved overall process economy through fewer tool interventions and steady component quality over longer machining campaigns.

Practical application notes and compatibility

The insert is supplied in the CNMG120408 format with the MM5 chipbreaker and is compatible with holders designed for rhombic 80° inserts. For stable results, select cutting parameters matched to the workpiece alloy and prioritise coolant or heat management strategies appropriate for stainless steels and superalloys. The insert’s specification supports a broad range of turning tasks from general finishing to moderate roughing, while custom cutting data can be provided on request by Metav Werkzeuge’s technical team.

FAQ

What materials is this insert suitable for?
The CNMG120408-MM5 WSM10S insert is formulated for stainless steels (ISO M) and heat‑resistant superalloys/titanium (ISO S), providing improved heat resistance and stable cutting edges in these groups.

Which chipbreaker should be selected for general turning tasks?
The MM5 chipbreaker integrated in this grade offers consistent chip control for a wide range of turning operations, suitable for both interrupted and continuous cuts.

How does the 0.8 mm corner radius affect the cutting result?
A 0.8 mm corner radius balances strength and edge definition, improving surface finish at lighter feeds while providing durability for heavier engagement compared with smaller radii.

Is this insert suitable for roughing as well as finishing?
Yes — the 0° negative free angle and robust grade make the insert appropriate for moderate roughing and finishing, depending on the selected cutting parameters and holder rigidity.

What is the product reference for ordering?
Order using SKU CNMG120408-MM5-WSM10S-WALTER, which identifies the CNMG120408 format with the WSM10S grade and MM5 chipbreaker from Walter Tools.
