TNMA160408-RK5 WKK10S — Dreieck 60° turning insert by Walter Tools (Tiger‑tec Silver, for cast iron)

A TNMA160408-RK5 WKK10S turning insert designed for reliable machining of cast iron, offering a coated‑carbide grade and a chipbreaker tuned to brittle, abrasive workpieces

• Tiger·tec Silver coating for extended tool life
• Optimised RK5 chipbreaker for cast iron chips
• Triangle 60° form for versatile turning geometry

Sustainably higher process stability when machining cast iron

The combination of the WKK10S grade and the Tiger·tec Silver coating delivers a balanced response to the abrasive wear typical of cast iron. The coated‑carbide chemistry is developed to resist flank and crater wear while maintaining a consistent cutting edge, which reduces unplanned regrinds and tool changes. As a result, the insert supports a more predictable production flow and contributes to reduced downtime. The chip control capability of the RK5 chipbreaker is especially relevant for the short, breaking chips produced from cast iron, improving evacuation and reducing the risk of built‑up edge.

Geometry and robustness that increase productivity and repeatability

The insert’s triangle 60° form and 0° (negative) relief angle provide a compact geometry that supports stable cutting forces and repeatable positioning in the toolholder. The specified corner radius of 0.8 mm helps balance edge strength and surface finish, permitting consistent component tolerances over longer tool life. The overall design and the A execution ensure compatibility with standard turning toolholders and allow straightforward indexing, which benefits series production by keeping set‑up times low and preserving part quality.

Practical handling, manufacturer quality and application guidance

Produced under the Walter Tools portfolio, this insert benefits from material and process knowledge aimed at industrial turning applications. The grade’s focus on cast iron machining ensures stable chip formation and reliable wear behaviour under typical conditions for that material group. For customers seeking application optimisation—or unsure whether this insert suits a specific casting grade—Metav Werkzeuge offers technical advice and machining recommendations to align cutting data and tool selection with the production task, supporting both efficiency and reproducible results.

FAQ

What materials is this insert intended for?
The TNMA160408‑RK5 WKK10S insert is designed primarily for the machining of cast iron, with the WKK10S grade and the Tiger‑tec Silver coating matched to abrasive, short‑chip casting materials.

What is the effect of the RK5 chipbreaker?
The RK5 chipbreaker is engineered to promote controlled, short chips when turning cast iron, supporting safe chip evacuation and reducing the likelihood of chip entanglement in the machining area.

How does the triangle 60° shape benefit turning operations?
The triangle 60° geometry offers a compact cutting edge that facilitates predictable cutting forces and stable seating in the toolholder, helping to maintain repeatable dimensions in series production.

Is the insert suitable for finishing as well as roughing?
The insert’s 0.8 mm corner radius and robust coated‑carbide grade provide a balance between edge strength and surface quality; selection for finishing or roughing should follow the specific cutting parameters and surface tolerance requirements.

Can Metav Werkzeuge provide cutting data for this insert?
Yes. Metav Werkzeuge can advise on cutting speeds, feeds and depths of cut tailored to the TNMA160408‑RK5 WKK10S and the particular cast iron grade in use to achieve optimal tool life and part quality.
