CCMT09T308-MW4 WKK10S – Turning insert with Tiger‑tec Silver coating for cast iron (Walter Tools)

The CCMT09T308-MW4 WKK10S is a rhombic 80° turning insert engineered for productive, abrasion‑resistant machining of cast iron components.

• Tiger‑tec Silver coating for wear resistance
• MW4 chipbreaker for controlled chip formation
• 7° clearance angle for stable cutting
• Rhombic 80° geometry for versatile turning

Consistent performance for abrasive cast iron work

The Tiger‑tec Silver coating and the WKK10S grade address the typical demands of cast iron: abrasive wear and frequently short, breaking chips. This combination is optimised to extend tool life under high abrasion loads while maintaining cutting-edge integrity. By selecting a coated carbide grade dedicated to group K materials, process windows become more predictable and the frequency of tool change‑overs is reduced. The result is improved machine uptime and repeatable productivity in both roughing and medium finishing operations.

Controlled chips and improved surface quality

The MW4 chipbreaker is designed to shape and evacuate chips reliably during chip-breaking cut conditions common with cast iron. Controlled chip formation reduces the risk of snarled swarf, lowers vibration levels and contributes directly to a more consistent surface finish. Together with the rhombic 80° geometry and a 0.8 mm corner radius, the cutting edge delivers robustness against impact and produces stable contact conditions at the tool tip, which benefits dimensional accuracy and reduces downstream finishing work.

Stable cutting behaviour and repeatability in production

A 7° clearance angle combined with a medium tolerance class (M) and a plate thickness T3 supports a balance between edge strength and accessibility in confined geometries. The insert geometry provides reliable seating in common toolholders and predictable wear patterns, enabling repeatable indexing intervals. For batch production environments this predictability translates into simplified tool management and consistent part quality across runs, especially where abrasive cast iron grades would otherwise shorten tool life.

Application focus and process security for cast iron components

This grade is particularly suited to the machining of cast iron (ISO group K) where abrasive wear and chip fragmentation are the main challenges. The insert’s design emphasises wear resistance and stable chip control rather than stainless steel or alloyed steel applications, which are not specified for this grade. In practice, the combination of a coated carbide grade, a targeted chipbreaker and a robust edge geometry helps to reduce manufacturing variability and supports cost‑effective throughput in demanding foundry and automotive components.

FAQ

What materials is this insert designed for?
The CCMT09T308-MW4 WKK10S turning insert from Walter Tools is designed for machining cast iron (ISO group K) and is optimised for the abrasive, short‑chip behaviour typical of those materials.

What does the MW4 chipbreaker provide?
The MW4 chipbreaker on this Walter Tools insert promotes controlled chip formation and safe evacuation of short chips, supporting stable cutting conditions and improved surface quality on cast iron components.

What are the key geometry values to consider for setup?
Key values are a rhombic 80° geometry, a 0.8 mm corner radius and a 7° clearance angle; these parameters influence edge strength, accessibility and the contact conditions at the tool tip.

Is this insert suitable for finishing operations?
Yes, the combination of a coated carbide grade and a controlled chipbreaker permits use in both productive roughing and medium finishing of cast‑iron parts, where stable chip control and wear resistance are required.

How does the Tiger‑tec Silver coating help in production?
The Tiger‑tec Silver coating increases resistance to abrasive wear and contributes to longer tool life under harsh cutting conditions, which supports higher process reliability in cast iron machining.
