DCMT11T304-MW4 WKK20S turning insert — Tiger‑tec Silver, optimised for cast iron, Walter Tools

The DCMT11T304-MW4 WKK20S is a coated carbide turning insert designed for productive machining of cast iron with emphasis on stable chip control and long tool life.

• Tiger‑tec Silver coated carbide grade WKK20S
• Optimised for abrasive cast iron machining
• Rhombus 55° geometry for secure clamping
• 0.4 mm corner radius and 7° clearance angle

Coating and grade engineered for abrasive cast iron

The Tiger‑tec Silver coating combined with the WKK20S carbide grade has been developed for the abrasive nature of cast iron. The coating reduces flank and crater wear by improving thermal resistance and reducing built‑up edge formation, which results in longer edge life and more predictable tool changes. For industrial turning operations where frequent interruptions are costly, the enhanced wear resistance translates into a measurable improvement in uptime and consistent surface quality on cast components.

Geometry and chip control for uninterrupted productivity

The Rhombus 55° form together with the MW4 chipbreaker produces short, controllable chips when turning cast iron, preventing entanglement and improving evacuation from the cut. The 0.4 mm corner radius stabilises the cutting edge for fine finishing passes while the 7° clearance angle helps maintain cutting geometry under load. This combination yields stable cutting forces, fewer rework operations and reliable component tolerances in series production.

Mechanical compatibility and handling advantages

With a T3 plate thickness and tolerance class M, the insert offers robust clamping security in standard heads designed for rhombic 55° inserts. The ISO-style designation facilitates quick matching with toolholders and reduces setup errors on the shop floor. The turning insert is a useful option for firms seeking straightforward retrofitting into existing toolholder inventories without the need for special adapters, supporting production flexibility.

Application focus and operational benefits

Specifically tailored for the K material group, the insert excels on grey and nodular cast irons where frequent short chips and abrasive wear define process requirements. The design promotes repeatable surface finish and dimensional stability across batch runs. For manufacturing engineers, the technical combination means fewer tool changes, consistent part quality and improved process reliability — valuable in both jobbing and high-volume environments.
