RCMT1605M0-RK4 WKK20S Turning insert (Tiger·tec Silver) – for cast iron (Walter Tools)

RCMT1605M0-RK4 WKK20S is a round indexable turning insert designed for reliable performance when machining cast iron, offering a coated-carbide grade and a chipforming geometry optimised for abrasive materials

• Tiger·tec Silver coating for wear resistance
• RK4 chipbreaker for stable chip control
• Round insert geometry for profile versatility
• 7° clearance angle for reduced rubbing

Consistent edge life for abrasive cast iron applications

The combination of the Tiger·tec Silver coating and the WKK20S grade provides a robust solution for machining cast iron, where abrasive wear and short, brittle chips are typical. The coated carbide composition increases resistance to abrasive damage and helps maintain a sharp cutting edge over longer production runs, which translates into fewer tool changes and improved uptime. The specified RK4 chipbreaker is engineered to manage the fragmented chips common with grey and nodular cast irons, supporting predictable chip flow and minimising the risk of tool or workpiece damage during interrupted cuts.

Geometry that improves process security and flexibility

With its round insert format and 7° clearance, this insert offers a balance between cutting stability and geometric versatility. The round shape permits multiple effective cutting edges and is suitable for profiling and general turning tasks, while the positive clearance reduces friction at the flank, lowering heat generation and wear. The product’s M tolerance class signals consistent dimensional accuracy, which supports repeatable set-ups and reproducible results across batches — a decisive factor in medium- to high-volume production where process security is essential.

Application-focused performance and handling benefits

This grade is explicitly tailored for cast iron applications and therefore adapts to the typical chip break behaviour of those materials. The coated grade combination provides advantages in abrasive environments, enabling longer tool life and stable surface finishes without aggressive interventions. Handling and indexing remain straightforward thanks to the well-known RCMT insert format; maintenance routines are simplified and changeover times are reduced, contributing to an efficient machining cycle and lower overall production costs when compared with less specialised solutions.
