DNMA150608-RK7 WKK10S — Indexable turning insert for cast iron, Walter Tools

A precision indexable turning insert, DNMA150608-RK7 WKK10S, designed for robust machining of cast iron components with a Tiger‑tec Silver coated carbide grade and an RK7 chipbreaker for stable, repeatable performance

• Tiger‑tec Silver coating technology
• WKK10S: grade optimised for cast iron
• RK7 chipbreaker for controlled chips
• Rhombus 55° geometry for flexible approach

High wear resistance for continuous production

The combination of the Tiger‑tec Silver coating and the WKK10S carbide grade delivers a marked improvement in resistance to abrasive wear, which is particularly relevant for the frequent, short, brittle chips encountered when machining cast iron. This results in longer edge life and fewer disruptive tool changes, which in turn supports uninterrupted production runs and improved overall economy. The RK7 chipbreaker further stabilises chip form, reducing the risk of built-up edge and helping to maintain consistent surface quality across serial runs.

Geometry that stabilises the cut and reduces rework

The Rhombus 55° shape and a 0.8 mm corner radius combine to offer a reliable edge strength and good access to a variety of turning profiles. The 0° (negative) clearance angle gives a robust cutting edge for interrupted cuts and heavy engagement, enhancing process stability under demanding conditions. Together these geometric features reduce vibration and edge chipping, which lowers scrap rates and the need for rework — a clear advantage for production environments focused on repeatability and uptime.

Practical benefits for cast‑iron applications

Designed specifically for group K (cast iron) machining according to ISO guidance, the coated insert minimises the common failure modes encountered with abrasive grey and nodular cast irons. The coating reduces adhesion and heat-related wear, delivering a predictable cutting behaviour and improved surface finish on the workpiece. This makes the insert a suitable choice for workshops and industrial producers manufacturing engine parts, pump housings or other cast‑iron components where process reliability and clean chip control are priorities.

Integration, handling and interchangeability

The insert’s ISO-style designation and tolerance class M ensure compatibility with standard DNMA toolholders and straightforward replacement in existing tool setups. The RK7 chipbreaker and the coated carbide composition simplify parameter selection for machinists, enabling quick tuning for feed and speed while keeping tool life consistent. For special production requirements, the DNMA150608-RK7 WKK10S can be specified as part of an optimised tooling strategy to increase throughput without compromising component quality.

FAQ

Which materials is this insert intended for? The DNMA150608-RK7 WKK10S insert from Walter Tools is intended primarily for machining cast iron (ISO group K), where its coating and grade provide abrasion resistance and predictable chip behaviour.

What advantages does the Tiger‑tec Silver coating offer? Tiger‑tec Silver on the WKK10S grade improves resistance to abrasive wear and reduces built‑up edge, which helps maintain cutting performance and surface finish when turning cast‑iron components with the Walter Tools insert.

How does the RK7 chipbreaker affect machining? The RK7 chipbreaker on this Walter Tools indexable insert produces short, controlled chips typical for cast iron, simplifying chip evacuation and enhancing process stability during continuous production.

Is the DNMA150608-RK7 suitable for interrupted cuts? Yes, the negative 0° clearance angle and robust geometry of the DNMA150608-RK7 WKK10S make it suitable for interrupted cuts and operations with variable engagement, offering improved edge strength.

How does the insert help increase process reliability? The combination of coated carbide grade, RK7 chip control and the Rhombus 55° form ensures consistent cutting behaviour, reduced tool wear and fewer changes, supporting reliable, repeatable machining cycles.
