VCMW160412-RK6 WKK10S – Rhombic 35° indexable insert for cast iron (Tiger·tec Silver) by Walter Tools

The VCMW160412-RK6 WKK10S is an indexable turning insert designed for productive machining of abrasive cast iron grades, combining a Tiger·tec Silver coating and an RK6 chipformer for stable, repeatable cutting performance.

• Tiger·tec Silver coated carbide grade WKK10S
• Optimised RK6 chipformer for cast iron
• 35° rhombic shape with 1.2 mm corner radius
• 7° clearance angle, 04 thickness code

Consistent wear resistance and reliable chip control for cast iron

The Tiger·tec Silver coating together with the WKK10S grade provides a pronounced resistance to abrasive wear typical of many cast iron alloys. The insert’s RK6 chipformer is engineered to manage short, breaking chips common when machining cast iron, reducing interruptions and protecting the cutting edge. The combination of surface treatment and substrate hardness means longer intervals between indexings, supporting a steady production rhythm and predictable tool life.

Repeatable accuracy and improved surface quality on turned parts

A rhombic 35° geometry with a 1.2 mm corner radius creates a balanced cutting edge that reduces vibration while producing consistent edge engagement. The moderate 7° clearance angle supports a positive cutting action that lowers cutting forces and helps maintain dimensional accuracy in serial production. Tolerance class M ensures the insert meets workshop demands for repeatability, translating into fewer rejects and smoother downstream processing.

Practical system benefits that boost productivity and lower downtime

The insert’s size and form factor make it compatible with standard indexable insert toolholders, enabling quick changes and minimal setup effort. The Tiger·tec Silver technology is focused on long running times under abrasive conditions, while the RK6 chip control reduces manual chip handling. Together these attributes contribute to more economical machining cycles, less unscheduled maintenance and a better overall throughput for cast iron components.
