VCMW160408-RK6 WKK10S Rhombic 35° indexable insert — Tiger·tec Silver, RK6 chipbreaker (Walter Tools)

The VCMW160408-RK6 WKK10S is a rhombic 35° indexable insert designed for productive turning of cast iron components in industrial machining applications.

Tiger·tec Silver coated carbide Optimised for cast iron (ISO K) RK6 chipbreaker for reliable chip control Rhombic 35° geometry with 0.8 mm corner radius

Durable coating and substrate for abrasive materials

The Tiger·tec Silver coating combined with the WKK10S coated carbide substrate is engineered for the abrasive nature of cast iron. The coating improves thermal stability and reduces flank wear, which extends tool life and maintains dimensional stability over longer cycles. For operations that demand repeatable component tolerances, this insert delivers consistent performance by reducing the frequency of tool changes and unplanned stoppages. The result is a measurable improvement in process efficiency and lower overall machining costs.

Controlled chip formation and secure edge performance

Equipped with the RK6 chipbreaker and a 0.8 mm corner radius, the insert produces short, easily managed chips typical for grey and nodular cast irons. The chipbreaker geometry promotes breakage close to the cutting edge, preventing long, stringy swarf and reducing the risk of surface damage. With a 7° clearance angle, the cutting edge runs with reduced friction, improving edge life and enabling stable machining at industrial feed rates. These attributes support uninterrupted production and reliable component surface quality.

Compact geometry for versatile turning operations

The rhombic 35° form provides a compact cutting geometry that balances strength and accessibility in tight tool setups. The insert has an inscribed circle of 16 and uses thickness code 04, offering a robust seat in common tool holders while allowing the positive rake necessary for finishing and semi-finishing passes. This geometry is particularly suitable where a combination of strength and low cutting forces is required, enabling shorter cycle times without compromising surface integrity. Compatibility with standard toolholders simplifies tool management in mixed-production environments.

Practical benefits and process guidance

Designed for ISO group K materials, the insert supports stable chip formation and predictable wear behaviour across a broad range of cast-iron grades. Its application reduces dressing and regrinding frequency and contributes to higher net output per tool life. For best results, pair the insert with appropriate cutting parameters for cast iron and ensure the tool holder offers solid clamping to exploit the edge stability. If machining conditions vary, the insert’s coated substrate provides a safety margin against thermal spikes and intermittent cuts, thus safeguarding component quality and uptime.
