CNMG120404-MU5 WSM20S Walter Tools — Turning indexable insert, Tiger·tec Silver, 0.4 mm nose radius

CNMG120404-MU5 WSM20S is a turning indexable insert designed for demanding machining of rostfreier Stahl and heat-resistant superalloys, delivering stable cutting with a MU5 chipbreaker in a rhombic 80° format.

• Tiger·tec Silver coating technology
• Optimised for rostfreier Stahl and superalloys
• Rhombic 80° form for stable cutting
• 0.4 mm nose radius for fine surface finish

Consistent machining performance for demanding alloys

This insert is engineered for repeatable results when machining rostfreier Stahl and high-temperature alloys. The combination of the WSM20S coated carbide and the MU5 chipbreaking geometry provides secure chip formation even under elevated cutting temperatures, reducing the risk of built-up edge and unplanned rework. Processors benefit from improved cycle-time stability and lower scrap rates due to the insert’s capacity to maintain a stable cutting edge under tough conditions.

Improved surface quality with a compact geometry

The rhombic 80° shape and 0.4 mm nose radius are chosen to balance robustness and finishing capability. The geometry produces a controlled contact zone on the workpiece, which helps to reduce vibration and yields a finer surface texture on the turned component. For operations where dimensional tolerance and surface integrity matter, this insert supports achieving tighter finishes without sacrificing productivity.

Extended tool life through advanced coating and grade

The Tiger·tec Silver technology, combined with the WSM20S grade, emphasises thermal stability and edge protection. This results in a longer usable life of the cutting edge in interrupted cuts and continuous turning alike. The coated hardmetal resists abrasive wear and thermal softening, enabling longer tool cycles and fewer tool changes—factors that contribute to lower cycle costs and a more efficient manufacturing flow.

Versatile application and straightforward specification

Available in the CNMG120404-MU5 format with a negative 0° rake, this insert is suitable for a wide range of turning operations including light to medium roughing and finishing passes in tough-to-cut materials. The MU5 chipbreaker supports reliable chip evacuation, while the M tolerance class and standard plate dimensions simplify integration with common toolholders. The specification makes it straightforward to select and deploy the insert within established turning programmes.

FAQ

What materials is this insert suitable for?
The CNMG120404-MU5 WSM20S insert is suitable for rostfreier Stahl and for high-temperature superalloys (designation S), as indicated by the WSM20S grade and Tiger·tec Silver coating.

How does the MU5 chipbreaker affect machining?
The MU5 chipbreaker promotes consistent chip formation and evacuation, improving process stability and reducing risk of built-up edge when cutting ductile, heat-generating materials.

What advantage does Tiger·tec Silver bring?
Tiger·tec Silver enhances thermal stability and wear resistance, extending the cutting-edge life of the WSM20S insert under demanding turning conditions.

Is the rhombic 80° form beneficial for strength or finish?
The rhombic 80° geometry offers a robust cutting edge for strength while permitting good access for finishing cuts, helping to combine durability with surface-quality capability.

Can this insert be used for both roughing and finishing?
Yes; with its MU5 chipbreaker and 0.4 mm nose radius, the insert is suitable for light to medium roughing and finishing operations in rostfreier Stahl and similar materials.
