CNMG120408-MW5 WKK10S Turning insert (Tiger·tec Silver) – for cast iron | Walter Tools

CNMG120408-MW5 WKK10S is a rhombic 80° turning insert designed for reliable, high‑performance cast iron machining in industrial turning applications

• Coated carbide Tiger·tec Silver
• Optimised MW5 chipbreaker for cast iron
• Rhombic 80° geometry with 0.8 mm nose radius

Efficient cutting in abrasive cast iron applications

The CNMG120408-MW5 WKK10S insert combines a Tiger·tec Silver coating with a specifically tuned grade for cast iron to deliver stable, repeatable cutting performance. The coated carbide substrate offers abrasion resistance suited to the short, brittle chips typical of grey and nodular cast irons, while the MW5 chipbreaker promotes predictable chip formation and evacuation. This combination reduces unexpected tool changes and contributes to a smoother production flow by maintaining cutting edge condition under demanding loads.

Geometry and edge preparation for consistent surface quality

The rhombic 80° geometry together with a 0.8 mm nose radius and a negative 0° rake provide a robust cutting edge able to withstand interrupted cuts and variable feed rates. These design elements translate into improved dimensional control and a reliable workpiece finish in serial production. Using an insert with this geometry simplifies toolholder selection and helps to maintain process stability when facing hard or abrasive cast iron grades.

Economic advantages through process stability and availability

Equipped with the WKK10S grade within the Tiger·tec Silver series, the insert is engineered for wear resistance and long service life in cast iron turning, which supports lower tooling costs per part over time. The insert’s profile and chip control reduce cycle interruptions and scrap risk, enhancing throughput and cost efficiency. For production environments seeking predictable tooling behaviour, this insert offers a balanced solution between cutting performance and lifetime economy.

FAQ

What materials is this insert suitable for?
The CNMG120408-MW5 WKK10S turning insert is designed primarily for machining cast iron (ISO group K), with a grade tuned to resist abrasive wear and handle short, breaking chips.

Which chipbreaker is fitted and why does it matter?
The insert uses the MW5 chipbreaker; this chip control geometry ensures predictable chip formation and evacuation when turning cast iron, improving process reliability and surface quality.

What are the key geometry details to consider for tooling setup?
This rhombic 80° insert has a 0.8 mm nose radius and a negative 0° rake; these features support robust edge strength and consistent dimensional stability in interrupted and steady cuts.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating enhances wear resistance and helps to maintain edge integrity under abrasive conditions common in cast iron turning, which contributes to longer tool life and fewer changeovers.

Is this insert suitable for heavy interrupted cuts?
Yes, the combination of rhombic geometry, 0.8 mm nose radius and negative rake provides a strong cutting edge that performs reliably under interrupted cutting conditions typical in many turning operations.
