CNMG160616-MM5 WSM20S — Turning Indexable Insert (Tiger·tec Silver) by Walter Tools

The CNMG160616-MM5 WSM20S is a coated indexable turning insert designed for heavy-duty machining of stainless steels and heat-resistant alloys, offering stable edge life and optimised chip control for demanding turning operations.

• Tiger·tec Silver coating technology
• Optimised chip control MM5 geometry
• For stainless steels and superalloys
• Rhombic 80° insert, 1.6 mm corner radius

Durable, heat-resistant coating for demanding alloys

The Tiger·tec Silver coating and the WSM20S grade are engineered to resist thermal and mechanical stress during interrupted cuts and long turning cycles. Coating technology reduces flank wear and supports a stable cutting edge, which translates into predictable tool life and fewer regrinds. For workshops processing stainless steels and heat-resistant superalloys, this insert improves machining reliability by delaying crater formation and sustaining surface finish under elevated cutting temperatures.

Controlled chip formation for safer turning operations

The MM5 chipbreaker geometry has been developed to promote consistent chip segmentation and evacuation in materials that tend to form long, stringy chips. The controlled chip flow reduces the risk of chip entanglement and improves coolant access at the cutting zone, resulting in fewer interruptions and a safer shop floor. Practical benefits include smoother toolpaths, reduced secondary operations to clear chips, and enhanced cycle-time stability for series production.

Geometry and edge preparation that support repeatability

A rhombic 80° shape combined with a 1.6 mm corner radius delivers a balance between strength and cutting performance: the robust corner supports heavier feeds while preserving edge security, and the negative 0° relief provides a stable cutting attitude under axial loads. These geometric choices help maintain dimensional accuracy and surface integrity with each indexation, making the insert suitable for both roughing and medium finishing passes where repeatable results matter.

Practical selection guidance and application scope

This insert is specified for material groups M (stainless steels) and S (heat-resistant superalloys and titanium) according to ISO designation, making it a versatile choice when one grade must cover several hard-to-machine materials. The nominal size code and thickness are provided to match common toolholders; users should verify holder compatibility and cutting parameters with tooling specialists. For tailored cutting data and optimisation, Metav Werkzeuge can provide application-specific recommendations and feed/speed guidance to exploit the insert’s full potential.

FAQ

What materials is this insert designed to machine?
The CNMG160616-MM5 WSM20S insert from Walter Tools is specified for stainless steels (ISO group M) and heat-resistant superalloys or titanium (ISO group S), offering an application window for demanding alloys.

How does the MM5 chipbreaker help in production?
The MM5 geometry promotes consistent chip segmentation and evacuation, reducing chip-related interruptions and improving process stability during longer turning cycles.

What are the geometric advantages of the rhombic 80° shape?
The rhombic 80° shape provides secure cutting engagement and versatility between roughing and medium finishing; combined with a 1.6 mm corner radius, it sustains edge strength under higher feed conditions.

Is the coating suitable for high-temperature cutting?
Yes; the Tiger·tec Silver coating on the WSM20S grade enhances thermal resistance and wear protection, helping to maintain edge life in thermally demanding operations.

How to ensure compatibility with tooling systems?
Confirm holder compatibility with the ISO designation CNMG160616-MM5 WSM20S and the plate thickness code; for matching toolholder and cutting data, consult Metav Werkzeuge for specific recommendations.
