Consistent productivity through enhanced wear resistance

The combination of the Tiger·tec Silver coating and the WKP25S carbide grade provides improved wear resistance and a stable cutting edge, extending the service interval between index changes. Coated carbide technology reduces abrasive and adhesive wear typical in the machining of both steel and cast iron, which leads to fewer unplanned tool changes and more predictable batch processing. In production environments where cycle times and uptime matter, this wear behaviour translates into measurable gains in overall equipment effectiveness.

Reliable chip control for safer boring operations

The 5R‑E67 chipbreaker geometry is engineered to promote defined chip formation when performing internal boring and enlarging operations. A dedicated chip control geometry reduces the risk of built-up edge and erratic chip shapes, which helps to protect the machined surface finish and the tool seat. The insert’s P4840P‑5R‑E67 form ensures a consistent cutting interface in the toolholder, supporting stable cutting forces and improved process security in serial machining.

Practical compatibility and easy inventory management

Certified for ISO material groups P (steel) and K (cast iron), the insert covers a broad material range commonly encountered in general engineering and component manufacturing. As a coated carbide indexable insert in the Tiger·tec Silver family, the grade is particularly suitable for mixed-production shops that require a compromise between edge stability and wear resistance. The ISO-style designation simplifies tooling lists and spare-part handling, enabling straightforward replacement and fewer SKUs in stock while maintaining machining performance across varying workpiece materials.
