VCMT110308-RK4 WKK20S indexable turning insert — RK4 chipbreaker, Tiger‑tec Silver for cast iron · Walter Tools

The VCMT110308-RK4 WKK20S is an indexable turning insert engineered for productive machining of cast iron components, combining a Rhombic 35° geometry with a chipbreaker tuned to brittle, short-turning chips.

• Tiger‑tec Silver coating
• RK4 chipbreaker for controlled chips
• Rhombic 35° geometry for flexible tool set-up
• 0.8 mm corner radius, tolerance class M

Increase productivity on cast iron components

The combination of a Tiger‑tec Silver coating and the RK4 chipbreaker delivers a pragmatic performance advantage when turning cast iron. The coated carbide grade provides improved wear resistance against the abrasive nature of cast materials, while the RK4 geometry shapes short, repeatable chips that reduce downtime from chip entanglement. For production environments this means a measurable increase in cycle stability and fewer interruptions for machine cleaning or reloading, supporting efficient batch throughput.

Achieve consistent surface finish and predictable tool life

A 0.8 mm corner radius and tolerance class M ensure repeatable edge strength and dimensional reliability. The moderate radius reduces the risk of edge chipping during interrupted cuts typical for cast iron workpieces, while the tolerance class supports accurate seat fitment and consistent cutting engagement. These technical choices translate directly into two practical benefits: a stable surface quality on finished parts and longer predictable performance per insert change, lowering overall machining costs.

Clear geometry and sensible handling for mixed‑fleet tooling

The Rhombic 35° form offers flexibility in toolholder setup and allows straightforward integration into existing turning tool families. The insert’s size and thickness codes conform to common system standards, simplifying inventory management and replacement. Its designation and grade are optimised specifically for the ISO K group, so tool selection is straightforward for cast iron applications and reduces the guesswork in mixed‑material production environments.

FAQ

What materials is this insert intended for?
The VCMT110308-RK4 WKK20S is formulated for machining cast iron (ISO group K) and is optimised for the abrasive wear and short, breaking chips common to these materials.

How does the RK4 chipbreaker benefit machining?
The RK4 chipbreaker controls chip shape and fragmentation when turning cast iron, reducing the risk of chip tangling and improving machine uptime.

Is the grade suitable for interrupted cuts?
Yes. The combination of a 0.8 mm corner radius and the coated carbide grade in the Tiger‑tec Silver family offers robust edge strength suitable for many interrupted cutting conditions.

Can this insert be used in standard toolholders?
The Rhombic 35° geometry and standard size coding allow integration into widely used turning toolholders, simplifying swaps and inventory handling.

What distinguishes the Tiger‑tec Silver series in daily use?
Tiger‑tec Silver provides enhanced wear resistance and thermal stability for demanding metalcutting tasks, which contributes to consistent performance and reduced insert consumption.
