CCMT09T304-MK4 WKK10S — Walter Tools turning insert, Tiger·tec Silver for cast iron

The CCMT09T304-MK4 WKK10S is a rhombic 80° indexable turning insert designed for efficient machining of cast iron, combining a coated carbide grade with a specialised chip control geometry

• Tiger·tec Silver coating for extended tool life
• Optimised for cast iron machining (K)
• Rhombic 80° insert with 0.4 mm corner radius
• 7° clearance angle for stable cutting performance

Consistent chip control increases productive cutting time

The combination of the Tiger·tec Silver coating and the WKK10S grade targets the specific challenges of cast iron, where abrasive wear and short, breaking chips are common. The MK4 chipbreaker is engineered to promote controlled chip formation, reducing frequent interruptions for chip clearing and lowering the risk of built-up edge. As a result, machining cycles achieve higher effective cutting time and a more predictable tool life, which supports stable production planning and fewer unscheduled tool changes.

Geometry and edge design for repeatable surface quality

The rhombic 80° insert geometry with a 0.4 mm corner radius and 7° clearance angle provides a balance between edge strength and accessibility for finishing passes. With a T3 plate thickness and tolerance class M, this design gives robust edge support under intermittent cutting typical in cast iron operations and improves repeatability across multiple indexings. The geometry supports consistent component finishes while maintaining a compromise between cutting forces and dimensional control in serial and small-batch runs.

Process reliability and easy integration into turning cells

As an indexable insert in the CCMT format, the component integrates into widely used toolholders for turning applications without the need for special fixtures. The coated carbide construction offers resistance to abrasive wear, contributing to predictable performance in abrasive cast iron grades. The product’s attributes promote process stability and support higher throughput with fewer tool interventions, making it suitable for workshops aiming to improve productivity while maintaining workpiece quality under varying production demands.

FAQ

Is this insert suitable for different cast iron grades?
The CCMT09T304-MK4 WKK10S grade is tailored for a broad range of cast iron materials and addresses abrasive wear and chip control specific to these grades.

What benefit does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances wear resistance and thermal stability, extending tool life and supporting more consistent cutting performance when machining cast iron.

Can the insert be used for finishing as well as roughing?
With its rhombic 80° geometry and a 0.4 mm corner radius, the insert is adaptable to both semi-finishing and finishing tasks, provided cutting data are adjusted according to the operation.

How does the MK4 chipbreaker improve productivity?
The MK4 chipbreaker promotes predictable chip formation in cast iron, minimising chip-related interruptions and enabling longer productive cutting intervals.

Which toolholders are compatible with this insert format?
The CCMT designation indicates compatibility with standard CCMT indexable turning toolholders; toolholder selection should match insert clamping and clearance requirements.
