DCMT11T304-FK6 WKK10S — Turning insert, Tiger·tec Silver, Walter Tools

The DCMT11T304-FK6 WKK10S is a rhombic 55° indexable turning insert optimised for economical, high-abrasion machining of cast iron components

• Tiger·tec Silver for abrasion resistance
• FK6 chipbreaker for controlled chips
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius for repeatable finishes

Longer tool life through optimised coating and grade

The WKK10S grade, part of the Tiger·tec Silver family, is a coated carbide solution developed for abrasive cast iron applications. Its surface treatment increases resistance to abrasive wear and thermal loading, which translates to extended tool life and fewer index changes during production. Using this metallurgical combination reduces overall tooling consumption and supports predictable process intervals, delivering measurable cost-efficiency and improved uptime for batch and continuous turning operations.

Reliable chip control and consistent surface quality

The FK6 chipbreaker geometry ensures reproducible chip formation when machining cast iron (ISO group K), lowering the risk of long stringy chips and enabling safer automated handling. Combined with the rhombic 55° shape and a 7° clearance angle, the insert maintains a stable cutting edge and predictable cutting forces, which helps to achieve consistent surface finishes and dimensional stability. These characteristics support higher feed rates where appropriate, improving cycle times without compromising quality.

Geometry and dimensions tailored for precision and flexibility

A 0.4 mm corner radius offers a balance between edge robustness and achievable roughness values, while the standard insert size 11 and thickness T3 provide compatibility with a wide range of turning toolholders. The compact geometry suits both finishing and light semi-finishing operations in cast iron, and the insert’s tolerance class M supports repeatable positioning in indexable tool assemblies. This combination makes the insert a practical choice when switching between batch sizes or when integrating into flexible production systems.

Process security and predictable results in daily machining

The insert’s design focuses on process security: consistent chip breakage, stable wear characteristics and easy indexability contribute to reduced setup time and fewer production interruptions. For operations that demand repeatable outcomes, the WKK10S grade helps maintain cutting-edge integrity over longer tool life, supporting more reliable part quality and reducing the likelihood of scrap. Where machinability varies across cast iron grades, the insert’s abrasion-resistant coating and chip control mitigate common variances, aiding operational robustness.

FAQ

What materials is this insert designed for?
The DCMT11T304-FK6 WKK10S insert (Walter Tools turning insert, SKU DCMT11T304-FK6-WKK10S-WALTER) is optimised for machining cast iron and is classified for ISO group K applications.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the WKK10S grade enhances abrasion resistance and thermal stability, which leads to extended tool life and more predictable wear behaviour in abrasive cast iron machining.

Which chipbreaker should be selected for stable chip control?
This insert features the FK6 chipbreaker, which is designed to produce short, controllable chips in cast iron, improving handling and reducing risk in automated processes.

Can the insert be used for finishing passes?
Yes—the 0.4 mm corner radius and rhombic 55° geometry are suitable for fine finishes and light semi-finishing operations, offering a good compromise between edge strength and surface quality.
