CCMT09T304-MW4 CCMT09T304-MW4 WKK20S indexable turning insert for cast iron — Walter Tools

A robust CCMT09T304‑MW4 WKK20S indexable turning insert optimised for efficient machining of cast‑iron components in industrial turning applications

• Tiger‑tec Silver coating for long tool life
• Optimised MW4 chipformer for short chips
• 7° clearance angle, 0.4 mm corner radius
• Rhombic 80° shape for versatile turning

Increased productivity through advanced coating and chip control

The combination of the Tiger‑tec Silver coating and the WKK20S grade delivers enhanced resistance to abrasive wear and improved edge stability when machining cast iron. The coated carbide substrate is formulated for the specific demands of grey and nodular cast irons, which typically produce short, brittle chips. The integrated MW4 chipformer supports consistent chip breaking, reducing interruptions and increasing machining uptime. As a result, cycle times are shortened and tool change frequency is reduced, supporting a more productive turning process.

Reliable surface quality and robust edge geometry

The rhombic 80° geometry with a 0.4 mm corner radius provides a balanced combination of strength and finishing capability: the radius reinforces the cutting edge for interrupted cuts while still enabling good surface finish on workpieces. The modest 7° clearance angle minimises rubbing and helps maintain stable cutting conditions over longer tool life. A tolerance class M ensures repeatable seat fit and positioning in standard toolholders, supporting process stability and predictable results in series production.

Versatile, application‑oriented design for shopfloor use

Designed as an indexable turning insert, the plate format (size 09, thickness T3) and the rhombic form make it suitable for a range of turning tasks, from roughing to finishing passes in cast‑iron components. The grade and geometry combination favours short, easily controlled chips, which helps to keep the machining area clean and reduces rework risk. The insert is compatible with standard clamping systems and is a practical choice where consistent chip control and tool life are priorities.

FAQ

What materials is this insert designed for?
The CCMT09T304‑MW4 WKK20S from Walter Tools is designed primarily for cast iron machining and is optimised for the abrasive wear and short chip behaviour typical of these materials.

How does the MW4 chipformer affect machining?
The MW4 chipformer produces reliably short chips in cast‑iron turning, reducing chip control issues and improving process continuity when using the CCMT09T304‑MW4 WKK20S insert.

Which toolholders are compatible with this insert?
The rhombic 80° format and tolerance class M ensure compatibility with standard indexable turning toolholders that accept CCMT‑style inserts; correct clamping and seat condition remain essential for optimal performance.

What benefits does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver coating improves abrasion resistance and edge life under the high‑wear conditions of cast‑iron turning, enhancing productivity and reducing tool change frequency for the Walter Tools insert.

Can this insert be used for finishing cuts?
Yes; the 0.4 mm corner radius and rhombic geometry balance edge strength and surface finish capability, making the insert suitable for both roughing and certain finishing passes in cast iron.
