CNMU120608-D57S WKP25S milling insert by Walter Tools — Tiger‑tec Silver, D57T chipbreaker

The CNMU120608-D57T WKP25S milling insert is a rhombic 80° indexable cutter designed for robust machining of steel and cast iron with a Tiger‑tec Silver coated carbide grade.

• Tiger‑tec Silver coating for long tool life
• Grade WKP25S for steel and cast iron
• Rhombic 80° shape with 0.8 mm corner radius

High-performance grade and coating for reliable machining

The combination of the WKP25S grade and the Tiger‑tec Silver coating provides a technical advantage in the machining of ISO P (steel) and ISO K (cast iron) workpieces. The insert’s coated carbide base and advanced coating technology reduce abrasive wear and improve edge stability under the high thermal loads typical when cutting steels, resulting in more consistent cycle times and fewer insert changes. This translates to measurable efficiency gains in series production and helps maintain part tolerances with less rework.

Geometry tailored to precision and surface quality

With a Rhombus 80° shape, 0.8 mm corner radius and 0° negative rake, the insert is engineered for shoulder milling and finishing operations where a controlled cutting engagement is required. The specified geometry supports a predictable cutting behaviour: steady chip formation, reduced vibration and improved surface finish. In practice, this means repeatable dimensional accuracy on profiles and shoulders, reducing downstream grinding or polishing requirements and supporting leaner machining processes.

Chip control and process stability for productivity

The dedicated D57T chipbreaker is optimised for fracturing and evacuating chips when machining steels and cast iron, promoting safer chip flow and preventing re-cutting. Stable chip control lowers the risk of edge damage and burr formation, thereby extending the effective lifetime of the insert and cutting tool assembly. By improving process stability, the insert contributes to reduced machine downtime and better overall equipment effectiveness (OEE) in both single‑pass and multi‑pass operations.

Practical integration and application advice

Designated by the ISO code CNMU120608-D57T WKP25S, the insert fits standard CNMU toolholders and is suitable for conventional milling set‑ups in job shops and production lines. Its tolerance class M and the standardised form factor facilitate simple stock management and rapid replacement during tool changes. For application notes, cutting data and feed‑per‑tooth guidance tailored to specific steel grades or cast iron types, Metav Werkzeuge can provide documented recommendations and cutting parameters to help integrate the insert into existing machining cycles.
