SDMT120408-F57 WKP25S indexable milling insert — Tiger‑tec Silver, for Steel and Cast iron (Walter Tools)

SDMT120408-F57 WKP25S is an indexable milling insert designed for medium to high‑productivity operations in steel and cast iron machining.

*Coated Tiger‑tec Silver grade WKP25S
*Chipbreaker F57 for controlled chip formation
*Square 90° shape with 15° clearance angle
*Corner radius 0.8 mm for balanced strength and finish

Increase throughput with a wear‑resistant, coated grade

The coated carbide composition of the Tiger‑tec Silver grade WKP25S offers a durable cutting edge tailored for the thermal and abrasive conditions of machining steel and cast iron. The combination of a modern coating system and a stable substrate results in consistently low flank wear and longer tool life, which directly contributes to fewer tool changes and higher machine uptime. Users will benefit from improved process stability during both roughing and semi‑finishing operations, with predictable tool performance under increased cutting speeds and depths.

Predictable geometry for consistent part quality

A square 90° shape combined with a 15° clearance angle and a corner radius of 0.8 mm ensures reliable engagement and repeatable results across batches. The controlled geometry reduces vibration and supports a steady tool‑workpiece interface, improving surface finish and dimensional accuracy. Tolerance class M supports reproducible seating in standard cutters, which simplifies tool presetting and reduces variability between inserts.

Efficient chip control and reduced cycle times

The F57 chipbreaker is engineered to produce short, manageable chips when machining the defined material groups, helping to prevent entanglement and improve evacuation in slotting and peripheral milling. Better chip control lowers the risk of workpiece damage and tool interruptions, enabling tighter cycle planning and, consequently, a more economical production rhythm. The insert’s balanced design supports stable cutting forces, which in turn permits higher feed rates without sacrificing surface quality.

Application spectrum and process recommendations

Designed for ISO group P / K, this insert is suitable for unalloyed and alloyed steel as well as cast iron applications as indicated in the technical grade description. The coated grade is optimised for a broad workpiece material range and common milling tasks; it performs well in both continuous and interrupted cuts. For best results, pair the insert with a rigid cutter body and an appropriate coolant strategy or MQL setup to extend life and maintain surface integrity.
