SCMW120408-RK6 WKK20S — Turning insert, Tiger‑tec Silver for cast iron (Walter Tools)

SCMW120408-RK6 WKK20S is a square turning insert designed for efficient machining of cast iron components in industrial turning applications

• Square 90° insert for versatile turning
• Tiger‑tec Silver coated carbide for durability
• RK6 chipbreaker tuned for cast iron
• 0.8 mm corner radius for robust edge strength

Boosted productivity through advanced coating and grade

The Tiger‑tec Silver coating combined with the WKK20S grade ensures excellent resistance to abrasive wear, a critical factor when machining cast iron. The coated carbide substrate is engineered to maintain cutting-edge integrity across longer tool life, reducing the frequency of index changes and machine idle time. In practice, this means more consistent cycle times and a lower tool inventory turnover, which translates directly into measurable productivity gains on the shop floor.

Reliable chip control and stable cutting geometry for consistent finishes

The integrated RK6 chipbreaker has been developed for the typically short, brittle chips produced by cast-iron materials, improving evacuation and reducing the risk of built-up edge. The square 90° geometry and 0.8 mm corner radius provide a robust cutting edge that withstands interrupted cuts and variability in workpiece material. These features combine to produce repeatable surface quality and dimensional consistency, helping to meet tight tolerances without frequent rework.

Practical application advice and compatibility information

This turning insert is optimised for machining cast iron according to ISO material group K and is particularly suited to operations that demand stability and predictable wear behaviour. The insert’s geometry and chip control make it a practical choice for medium to heavy roughing and general finishing tasks on cast-iron components. For machining strategies, pairing the insert with stable tool holders and appropriate cutting parameters will further extend service life and improve process reliability. For technical queries or recommendations on cutting data, Metav Werkzeuge offers specialist consultation to match the insert to specific machines and cycles.
