DNMA150408-RK5 WKK20S indexable turning insert — Tiger‑tec Silver, RK5 chipbreaker, for cast iron | Walter Tools

An indexable turning insert, DNMA150408-RK5 WKK20S, designed for stable, high‑productivity turning of cast iron components in industrial machining environments.

• Tiger·tec Silver coating for enhanced wear resistance
• RK5 chipbreaker optimised for cast iron chip control
• Rhombic 55° shape for versatile turning applications
• 0.8 mm corner radius for improved edge stability

Maximise productivity when turning cast iron

The insert’s Tiger‑tec Silver coating and the WKK20S coated‑carbide grade are engineered specifically for abrasive cast iron applications. This composition promotes stable chip formation and reduces flank wear, which leads to longer cutting intervals and fewer tool changes. The result is measurable improvements in process efficiency and component throughput, especially in batch production and high‑volume turning operations where tool life and consistency directly affect cost per part.

Geometry that controls chips and protects the edge

Featuring a rhombic 55° platform and the RK5 chipbreaker, the geometry of this insert supports controlled, short chips typical of cast iron machining. The 0.8 mm corner radius increases edge strength and resistance to chipping, while the 0° (negative) rake provides a robust cutting edge for interrupted cuts or heavy engagement. These design choices combine to reduce downtime from edge failure and to maintain surface quality over longer tool life.

Consistent tool life and process security through coating and grade

The coated carbide grade in the Tiger‑tec Silver family offers a balance between wear resistance and toughness for abrasive materials. This provides predictable performance across different cast iron types and cutting conditions, improving repeatability in production. The insert’s coated carbide construction helps maintain cutting geometry under thermal and mechanical stress, supporting high process reliability and a steady surface finish on workpieces.

FAQ

What materials is this insert intended for?
The DNMA150408-RK5 WKK20S by Walter Tools is specifically suited to machining cast iron (material group K) and has been optimised for the abrasive wear and short, breaking chips typical of those materials.

How does the RK5 chipbreaker benefit production?
The RK5 chipbreaker on the DNMA150408-RK5 WKK20S controls chip formation to produce short, safely breaking chips, which reduces the risk of entanglement and supports consistent surface quality during cast‑iron turning.

What advantage does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver coating increases wear resistance and thermal stability for the insert, helping to prolong tool life and ensure repeatable performance in demanding cast‑iron machining tasks.
