CNMG120408-MP5 WKK10S — Turning indexable insert, Tiger·tec Silver, for cast iron (Walter Tools)

CNMG120408-MP5 WKK10S is a rhombic 80° indexable turning insert designed for efficient machining of cast iron components in industrial turning applications

• Tiger·tec Silver coating for high wear resistance
• Optimised for abrasive cast iron machining
• MP5 chipbreaker for short, controllable chips
• Rhombic 80° shape with 0.8 mm corner radius

Maximise metal removal rates with a grade tuned to cast iron

The combination of the Tiger·tec Silver coating and the WKK10S grade provides a clear productivity advantage when machining cast iron. The coating reduces abrasive wear from hard graphite phases and maintains a consistent cutting edge over extended cycles, which translates into fewer insert changes and reduced spindle downtime. In practice, the MP5 chipbreaker promotes short, predictable chips that ease evacuation and reduce the risk of workpiece damage, supporting higher feed rates without compromising surface finish.

Robust geometry for interrupted cuts and heavy engagement

The rhombic 80° form and the 0° (negative) rake angle create a mechanically strong cutting edge suited to heavy engagement and interrupted cuts often encountered in roughing operations. The 0.8 mm corner radius balances strength and edge life while still allowing acceptable surface quality in semi-finish passes. These geometric choices mean the insert tolerates higher radial depths of cut and provides repeatable machining behaviour, improving process reliability in batch and single-piece production.

Consistent performance and simplified process planning

As a coated carbide turning solution, the insert supports a wide range of cast-iron grades identified under ISO group K. The coating and substrate pairing deliver predictable wear progression, making tool life estimation and process planning more straightforward. For machining centres requiring reproducible outcomes, the insert’s tolerance class M and standardised form simplify toolholder selection and tool management. For specification queries or tailored machining advice, Metav Werkzeuge supplies cutting data and recommendations to align insert choice with cycle-time and surface-quality targets.

FAQ

What materials is this insert designed for?
The CNMG120408-MP5 WKK10S is designed primarily for cast iron applications (ISO group K) and is tuned to handle abrasive graphite-rich workpieces.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating reduces abrasive wear on the carbide substrate, extending insert life and maintaining cutting-edge stability during extended turning cycles.

What chip control can be expected with the MP5 chipbreaker?
The MP5 chipbreaker produces short, controllable chips ideal for safe evacuation in turning operations, helping to protect the workpiece and tooling.

Is this insert suitable for roughing and finishing?
Yes — the 0° (negative) rake and 0.8 mm corner radius provide robust edge strength for roughing, while the geometry still permits acceptable surface quality in semi-finishing passes.
